Calculator ∞ for Positive User Reviews
✓ Really useful all round calculatorBest calculator I have found for the iPad. It does the job and has advanced functionality for the odd occasions I need it. In my opinion it is much better than any traditional calculator as the different usage modes are separated out which means the keys are not overloaded with functions e.g. When I'm working with binary I am usually not interested in trig functionality. Also, love the graphing and root solving functionality for when I want to quickly check something..Version: 4.7.3
✓ Very helpfulA very useful app with both helpful and interesting features. There is though something missing, the conversation of base numbers. Even if it's just Hex, Binary and Denary please add it!.Version: 4.7.3
✓ Conversions out of calc app?I have enjoyed using this app. Now I enjoy it less due to your making the conversions aspect be on its own app. Why did you do this? It’s very inconvenient. If you’re just trying to create extra income you could at least make it a paid addition to the original app so I don’t have to use two separate apps to do what was possible with one..Version: 5.5.1
✓ Nice appThis is a very good app, with a steep learning curve. In casual use it seems to be free of bugs and other annoyances..Version: 4.7.3
✓ Best CalculatorThis is my favorite calculator. The algebraic approach is great, and equation solving is terrific. I just hope that future upgrades might include graphing - I'll be watching for it..Version: 1.1.1
✓ Very good calculator - FX83/85 equivalentThis calculator has similar functionality as a Casio Fx83/85 series of calculators but at a fraction of the price. Only improvement needed is between switching screens. I have stopped using the swipe technique and the functions I want are always on the other screen. Being able to define which functions you have on each screen would address this..Version: 4.3
✓ Really good calculator appI'm over 50, an engineer, I need a calculator like the one I used in my twenties akin to the Casio fx-991. This calculator app does the job, and some. Nice touch!.Version: 3.4.5
✓ Best calculator ever!This is easily the best calculator app for iPhone or iPad, and is well worth the asking price. This app does all I need and far more - i only just found out it does unit conversions, which is a huge bonus!.Version: 4.4
✓ Why did they change so muchI just saw the new look for the app yesterday. While I like the sleek look of the new calculator, the bars under the buttons are confusing and look bad, and need to have an option to turn them off. Also, I appreciated having a drop down for the conversions, instead of having to type them in, because now I don’t know what the calculator can convert. If these 2 things were added, this would be a 5 star calculator..Version: 5.5.1
✓ Versatile - Brilliant!From students to programmers, this has a vast and complete range of features. It compliments many tasks. Extremely handy and, as far as I've been able to tell, faultless!.Version: 4.5
✓ I love itI’m studying mechanical engineering at college and and I’ve sought an app like this because I needed it very much! Right now I find it and i’m so happy and I upgraded really fast. I’m really appreciate for it. and I have a request for maker of this app, that is I’d like to add Persian (farsi) language to this app because there are so many people here that they need it as my friend and my teachers too. so please add it❤️.Version: 4.8.3
✓ GreatBest calculator app I have ever used. Great functionality and usability. For me, no app has been able to replace my actual calculator, but this one comes close..Version: 4.4
✓ Very usefulI no longer need to bring my CAS home after school!.Version: 3.4
✓ Tried five calculator apps; this is the one I’ll useBought four other paid calculator apps before finding this one, including the two more-expensive apps that seem to top most reviews / ratings of iPhone / iPad calculator apps. More than the others, Calculator Infinity meets needs for a calculator that works seamlessly across disciplines; engineering, statistics and accounting (scientific too, not my need). Especially like that it clearly displays algebraic equations as they are entered - great for avoiding errors and for showing others what’s going on - and user functions are so easy to create and use. As a calculator that does absolutely everything it takes a bit of practice to use, and it’s unit conversion feature is more kludgy than others. However the other calculator apps purchased will likely be deleted from my devices soon; this one does it all well..Version: 5.2
✓ CalculaterVery good app!.Version: 4.7
✓ Great CalculatorThis calculator is brilliant and is very easy to use. It is an inexpensive scientific calculator and contains every function you need..Version: 4.1.14
✓ The only one you need.I found a bug and they fix it. Very easy to use and include a huge converter. Very complete, I recommend. 10/10!.Version: 5.1
✓ Strong AppIt is a good calculator.Version: 4.5
✓ Good but NotGood but the fact that when you use photos to make it a bit easier , you see you’d probably do something easy like 1+7. The first test one works so you’d do something complex like x=3+4 3+x, it would still show 1+7. No matter what you do it shows 1+7. You change your mathematical question to 0+0, it still showes 1+7! What a waste of money!.Version: 5.6.1
✓ Final calculator you’ll ever needAs a long time land surveyor who has worked in the engineering fields from electrical engineering to structural engineering to civil engineering this calculator has done it all for me. I have built highway bridges to miles of highway with this app. I have used it also to teach my kids geometry, trig, and algebra using it. The price is same as a casio fx-115es plus i use which u can use on state exams. Ive used every calculator out there from old hp48s to hp 35s to graphing calculators of all sorts. This one like i said is worth evry penny..Version: 5.6.3
✓ Great app10 years ago you'd have had to buy a vastly expensive graphical calculator to do a quarter of what this one does... Excellent and powerful..Version: 3.3
✓ Very good and feature-complete, with one star offThe star off is for the (undeclared in the marketing) in-app purchase necessary to use a feature, namely the OCR/handwriting recognition. The charge isn’t even the issue, services cost money, but it shouldn’t be on potential customers to find this out after getting the paid app..Version: 5.9
✓ Great calculatorFor day to day and scientific & engineering needs this is A+++.Version: 4.7
✓ Full blown TI-like calc on iOSI used the free version for a year or so and bought pro when on sale. Best decision hah! The pro version of this calc can do basically anything. There are even some calculus level functions I’ve only ever seen on big TI calcs like the 89. I love that it can be a side app on the iPad Pro next to another app, and its size is adjustable without UI problems. Great for multitasking. Only criticism is that I can’t set it as my default calculator app (Apple problem). Also, could use a GUI update, feels a little 2013 when it comes to the graphical assets..Version: 5.8.7
✓ Better than Apple's for sure.Some asthetic improvements would be nice. Can't find randians for trigonometric functions though..Version: 4.8.3
✓ Love the new interface design.Love the new interface design..Version: 5.5.5
✓ Best calculatorI'm so glad I bought this. Good for simple calculator, matrix algebra, equations solving, even simple integral and derivatives. Bought this 4 years ago, still use it today.Version: 5.2
✓ Best CalculatorAs a maths teacher I have looked at quite a few calculators. This is by far the best one as it has "write view" as standard..Version: 3.1
✓ Wow!I am so impressed with this calculator. I’ve been using the free version for awhile but the paid version is something else. So useful and by far the best calculator app I’ve used..Version: 5.5.5
✓ BrilliantAn excellent calculator, the closest you'll get to a Casio on a phone, easy to use and with heaps of functions!.Version: 4.4
✓ WorksUsed for years and functions like a calculator..Version: 4.1.11
✓ The best calculator app and technical support money can buyI was in need of a calculator that could solve engineering power supply resistor values and stumbled on this app. My questions to technical support were answered within an hour and explained in detail very well. I highly recommend this calculator..Version: 5.0
✓ Ideal for scientists & mathematiciansBrilliant app. Provides a huge range of scientific & mathematical capabilities making calculations a breeze. This is the most advanced calculator and the easiest to use that I have ever tried..Version: 4.4
✓ Smart calculatorThis calculator is amazing. Unfortunately, university has a no smart phone policy which means I can not use this calculator app during tests. So i still have to have a traditional scientific calculator. If your company has any suggestions or remedies that might help persuade the university policies to change this unfortunate circumstance, I encourage you in doing so..Version: 4.4
✓ Wonderful math calculator, with history!This math app performs all math functions efficiently and accurately. Easy and logical entry formats. I am most pleased with two features: (1) entries in logical notation and (2) unlimited history of entries and results. Just scroll back to see each entry and resultant calculations, with revisions possible at any point in a long string. Thanks!.Version: 5.8.1
✓ GoodDas ist gut.Version: 5.9.2
✓ Amazing calculatorThis is by far the best calculator on the app store. It's got many handy features and is easy to use. Unlike many other calculators, this one actually displays the equation at the top clearly..Version: 1.3.2
✓ You have to pay for new featuresI love this app. It’s an amazing app and a great calculator. However the new UI is very strange. It used to be set up in a much better way, but it looks much more aesthetically pleasing now then it did before. It makes sense why they changed it. However my problem lies with me not being able to use the camera function without paying a EVERY MONTH. It doesn’t make sense why they would make you pay for it when apps like Photomath exist. I get that you need to use a third party software that must cost a lot to borrow, but c’mon. You guys should try to develop the best software out there. I gotta say all your other functions are amazing. If you develop your own amazing one then you wouldn’t really have to charge us for it. I get that this way is easier, but no one is actually going to buy it unfortunately. They already payed a decent amount for the app. Great idea to have a photo mode, but sadly poor execution..Version: 5.5.2
✓ CalculatorExcellent calculator.Version: 5.9
✓ ExcellentThis is easily the best calculator app I've found for the iPhone. I don't use anything else now..Version: 4.4
✓ Top CalculatorI use this app all the time. Had a few different "paid for" calculator apps, and this has been the best..Version: 4.6
✓ Calculator infinityOverall good. A calculator with a touch screen - very good!! Suggestions for improvements: 1 An improved retrieval for "last calc or result " . At present it's a bit clunky 2 improved ability to program the app. At present it is limited and a bit clunky Overall I definitely recommend this app😊👍.Version: 4.4
✓ Love this app!Can there be an update to the numbers on the screen? I like how I can type a ton of numbers, but instead of them going on forever in one line I think it would be better if they could wrap around on the screen and continue underneath the first line of numbers to the second line and so on!.Version: 5.5
✓ AmazingVery happy with this app.Version: 5.5.6
✓ Great app but one flawThe modulus operator does not give you the correct result when you have a negative number as the first operand. For instance right now if you do -5 mod 4 you will get -1 which is incorrect. The correct answer is 3. Other than that this app has been great. Used I use an iPad Pro for all my note taking and it so nice to just swipe from the right and boom there’s my calculator. Best calculator app other than this modulus issue..Version: 4.8.3
✓ Horrible updateThis new User Interface has destroyed the seamless experience that this calculator offered before. Key strokes have a lag which causes the calculator to miss the some of the keys that were pressed. The History list now requires you to press insert when you want to make changes in an equation you used before. I can’t even explain how much this update has made it difficult to continue using this calculator. Developers should be fired for trying to fix something that didn’t need to be fixed..Version: 5.6.2
✓ This calculator is actually good, the results are accurateSomebody just mentioned that the result was inaccurate. First, for the trigonometry part it is accurate since it is using the radian unit, not degree unit. I think all results are accurate as far as I tested it. Also, somebody complained issues like when he inputed 1/1.31, the result had been turned into 100/131, that is because you use the fraction mode, not decimal mode. Don’t give wrong reviews due to your lack of knowledge..Version: 5.8.3
✓ Excellent calculator, excellent valueBest money spent on a calculator ever. Doesn't have some advanced functions (like plotting) but considering the price, I couldn't ask for more. Very stable with no bugs so far..Version: 4.3.1
✓ AwesomeGreat app - does everything I need and more.Version: 4.6
✓ Great! A+Great calculator for algebra don’t know about the others functions as I only use it for algebra but it certainly was worth the seven dollars it cost me works great for any equations and the like A+++++.Version: 4.6.2
✓ Outstanding!Remarkable work! Thank you!.Version: 5.7
✓ SmithkLove this calculator. Does everything I need for minor math and engineering ..Version: 4.6
✓ Works Great!Pretty incredible for the price, works for several simple and complex types of functions intuitively and easily. I haven't used one of the expensive TI graphing/scientific calculators in many years (before the invention of the smartphone hahaha), but unless those do a specific function 100x's more efficiently that I have to do 100+ times daily, I can't justify adding a clunky piece of hardware that I can just simply do with my phone. Highly recommended!!!.Version: 4.6
✓ Excellent Scientific CalculatorI have had a fascination for calculators since I bought a slide rule in 1969 when I was 16. My first electronic calculator was the Texas Instruments TI-2510 in 1974. Since then I have had several calculators that have increased in the number of functions and complexity. But this is the most capable and comprehensive calculator I have ever had and have no hesitation in recommending it..Version: 5.2
✓ Good CalculatorI gave it four; but would have given it 5 if had more stat's applications. Nevertheles, I would recommend it to anyone who wants a good calculator on their phone or iPad..Version: 4.3
✓ I love how active the development and evolution of this app isI do not need a calculator on my phone or iPad regularly but I find that when I do need something more a bit robust than the built in calculator on my phone or need an app at all as one is not included on the iPad that this is one of the first I turn to. It makes sense and is well designed..Version: 5.5.3
✓ Where is my calculatorI was happy with the standard look and feel of the old calculator, like on my phone . Why change the basics. When I want more I will look for it. This is bad product enhancement..Version: 5.5
✓ The Statistics Mode is a beastMade my job much easier..Version: 5.6.1
✓ Very comprehensiveSmarter than I am.Version: 5.8.7
✓ Fantastic functionality (pardon the pun)This calculator does all kind of neat stuff. Without restating its functions (the app description does that well), I can say that as a scientist, engineer, and pilot, this calculator exceeds my very demanding expectations in so many ways. It makes beautiful graphs that are traceable and zoomable. It works with equations with ease, even complex ones. Calculus and statistics are no problem (again, pardon my pun) for this thing, too. I’d love it if it had a built in E6B, but other than that, it has everything! I totally recommend it to students, teachers, and professionals in STEM! Great work devs!.Version: 4.8.3
✓ Fantastic CalculatorComprehensive range of functions. Easy to use and edit. Even does integrals, solves equations (e.g. Cubics) and simultaneous equations..Version: 3.1
✓ Works wellGreat calculator but takes a bit of getting used to. Would recommend..Version: 4.6
✓ Both editions are amazingStarted out with the free Calculator # and later upgraded to the full version. Both calculators are powerhouses of phone apps that are a must have for anyone who ever needs any kind of calculator on their device. The apps are very intuitive and extremely well made, and support a wide array of options making life so much easier. Highly recommend to everyone..Version: 5.1
✓ Woops dunno what happened to last rating...Very good calculator from beginner to advanced. Love the extra answer conversion thing that converts units. I'm not very mathematical but it's a great easy calculator and I am doing an electrical apprenticeship and it's helping me breeze through it. Glad I bought it..Version: 4.1.14
✓ New bugs but great updateThe new update has had me run into about 3 bugs that made me need to reset the app and there are also a few things that I can’t seem to properly hit as the buttons are now much smaller. Maybe put the button sizes back and add some more slides for the buttons? I’ve had this app for 4 years now, paid for it, and have used it a ton since. I know you guys worked hard on this but these issues are not what I paid for for this app..Version: 5.5
✓ New interface is crapI thought I was the only one who had a problem with the new interface, but it turns out that a lot of users also have the same problem. The interface of this calculator was what attracted me to it and made me buy it in spite of the fact that I had other paid-for calculator apps that are more expensive. Now the interface is horrible and time wasting. At least give the option of being able to switch to “classic” at will.Version: 5.6
✓ Great calculator!Some suggestions: Keys on the main keyboard page (flat, dark mode) have gray backgrounds witch is great, but what about the other extended keyboard pages?! Did the designers forget them?! Zero key is one of the most used keys on most calculators and so the zero key is one of the largest. But here, it’s not only the same size, but also is just above the menu key and you should be careful to not touch the menu key by mistake. The menu bar color (blue) is not matched with the overall dark design. Maybe a gray and darker color would be great. Even an auto hide option for menu bar would be awesome. Thanks for this great and powerful calculator!.Version: 5.8.7
✓ ExcellentAs a part time Maths degree student this is the perfect accomplice to digital copies of my study text - as good as the 'staple' Casio calculators. Could do with landscape view as an alternative to having to swipe for additional menus but overall excellent..Version: 4.4
✓ GoodIt’s pretty great, but a vital function is missing or maybe I can’t find it. You aren’t able to input previous results (from more than one calculation prior) into a new calculation, no way to paste numbers either. One review says they can’t calculate fractions but you can indeed convert decimals to fractions by pressing the bottom right button on the main screen.Version: 5.2
✓ Almost PerfectGreat Calculator, well thought through, the only issue is selecting the conversion units needs some stabilization . But all in all a great app. I would recommend it to anyone.Version: 4.7
✓ Full of featuresA complete calculator with lots of features that are easy to get to.Version: 4.1.14
✓ Great appCould be more user-friendly by providing a more detailed instruction manual..Version: 4.2
✓ Not a fan of the interfaceI’ve had this calculator app for several years and have loved. So far, I like most of the new functionality of the updated version, but the new interface is not so great. The keys are small Anne unresponsive. Pulling up previous calculations is not as intuitive as before. If it stays like this, I will definitely be looking for a new calculator app soon. The unresponsiveness of the keys is making this app unreliable and unusable. Please fix it soon..Version: 5.5.1
✓ GreatNo really, it's great. I'm not just writing this because the app keeps pestering me for a review....Version: 4.1.14
✓ Infinity calculatorExcellent calculator. iPhone version great too. Loads of different functions for every problem..Version: 4.2
✓ Best calculator appGreat app, easy to use but immensely powerful. Highly recommended..Version: 3.0
✓ Great calculatorThis is the BEST of all of the calculators that I have tried. So many functions That I do not need to use. A fun calc anyway..Version: 3.1
✓ Infinity calculatorExcellent. Very useful. Comes in handy so many times..Version: 5.9
✓ Nice. Needs landscape mode on iPhoneReally nice calculator and more. My only frustration is having to swipe keys left and right for basic trig functions etc. A landscape orientation with smaller buttons would seem to be what's needed. iPad layout is nice. But even the iPad mini is too big to cart around as a calculator, for me. Anyway, it's otherwise very good indeed!.Version: 4.4
✓ FantasticI'm a y11 methods student in Australia and this app would've been able to do anything that we've been doing effortlessly and while being easier to use than the casio class pad. It's a must have for any math student. Effortless, powerful and easy to use absolutely brilliant I wish I found it earlier..Version: 4.5
✓ Change it backI hate to be one of those people who only rates something when they’re dissatisfied actually I think I gave this calculator a great rating when I paid for it. Changes were made a few weeks ago and now it doesn’t work all the time. A calculator needs to work all the time because I don’t have a need for two calculators..Version: 5.5.7
✓ Good calculatorFantastic and easy to calculate lots of complicated method with clear diagram, however I cannot use in my exam with my phone.....Version: 4.5
✓ Super UsefulI was searching for a good scientific calculator to help out with my uni math subjects. After trying out a variety on the app store, this is the one that I like the most..Version: 5.2
✓ Latest upgrade is a big downgradeAnother example of breaking a successful app for no apparent reason. If it’s not broken why “fix”it?.Version: 5.5
✓ Great!!Now I have my super calculator 🤓.Version: 4.1.14
✓ Easy to Use and EfficientThe way this calculator allows you to enter calculation formulas in forward form (e.g., sin 45 instead of 45 sin; -1 instead of 1-), and how it understands notation shortcuts such as 4 pi = 4 times pi makes entering calculations much more efficient and much less error prone than traditional scientific calculators. You also see a scrolling display of your total calculation entry (instead of the display refreshing with each intermediate calculation value). This helps you to check that you entered a long calculation correctly. Highly recommended..Version: 5.1
✓ What I’ve been looking for.This calculator is well worth its money. It has so many useful features that it’s insane how little this costs. Also, this calculator has the one feature I’ve been looking for, and that is to be able to input a variable anywhere into an equation and it will solve instead of the long process of rearranging the equation to solve it. Also has a great converter, and other useful modes..Version: 5.1
✓ Excellent calculatorExcellent calculator, Just a couple of thoughts you need to be able to edit the x and y ranges for the graph and not keep then fixed, for example plotting sin(x) on the graph, the x range is -360 to 360 the y is -1 to 1 or even have an auto fit button, for most graphs people will know the x range that it is to be plotted over, calculate the results and then display. That way we don't have to change the graphs to 100sin(x) just to see them. Also make use of the nice hires displays and have a thinner line or select line thickness and a landscape mode for the graph..Version: 4.3
✓ Very useful!Very well payed out and incredibly useful!.Version: 4.6.2
✓ Very GoodExcellent calculator with lots of functions. Totally recommended..Version: 4.4
✓ A must haveRecently, updates have been aggressively plenty and nothing noticeable was broken in the process. UI changes are not an issue for me though there is a risk of bloating but I trust the developers are smart..Version: 5.5.7
✓ A very impressive calculator ideal for equationsOne of a few calculators that let you basically type in a full equation and then just gives the answer. Very impressed with the features and style if this fully equipped calculator.. I like the way you can click on your calculations and insert more calculations at any point so no worries if you miss type or miss a portion. Not sure if necessary to buy the upgrade as can not really see any useful improvements over the free version. However, happy to buy to support a developer of such a good app'.Version: 1.2
✓ A nice calculator with all the features you could wantBrought this about 5 years ago and it is still good and gets updates for new devices..Version: 5.8.2
✓ Uncalculable AwesomenessLooking for a comprehensive, slick, useable calculator - small price to pay for a well executed tool..Version: 5.1
✓ Amazing calculator!This calculator is purely amazing. It has more operators then you will ever need, it’s quite accurate, and can prove to be very useful in a large variety of situations! Unlike all those other calculators, which are severely limited compared to this. I’ve trusted this calculator for a year or two now and it continues to serve me well to this day. (Thank you for bringing back the carbon layout! You guys are awesome!).Version: 5.5.2
✓ Excellent CalculatorFor engineering students. In case you left your calculator at home, don't worry, you have got this app..Version: 4.6.2
✓ Great calculator!I'm just starting to restudy high school maths at the higher level and this app seems to be just the ticket :).Version: 3.2
✓ The updated version is excellentThe later version is outstanding. Lots of functions that go beyond the needs of any individual. Great effort..Version: 5.5
✓ Perfect for a science studentGreat calculator!!!.Version: 4.7.3
✓ Love this appHave been an avid user since high school, and it's served me well through MIT and beyond. One suggestion regarding the latest update though. I'd reccommend some sort of color change for the whole button when you press it. On the light and dark themes, only the number changes, and this is impossible to see when you're pressing the button, so it's hard to get that instant feedback. Silver theme fixes this, though, so no real complaints here! Keep doing what you're doing fellas. It's working!.Version: 5.6.2
✓ Excellent appA one-stop, does everything calculator that suits school kids to professionals..Version: 4.6
✓ Best Calculator Watch on App Store!!!!!Does the basic things like simple operations and complicated things like graphic functions. It’s easy to use and has a nice dark theme, which I use. My only suggestion is to create an Apple Watch app of this calculator: that can do quick and simple operations. Hope you guys can continues to support this app and make enhancements to it because it feels sluggish at times..Version: 4.6.2
✓ Fantastic if you have a rectangular screenPlease use safeAreaLayoutGuide and drop the custom status bar. It’s the only thing stopping me from giving a 5 star rating..Version: 5.8
✓ Best calculator appHave been using for over a year and have been very impressed..Version: 3.4
✓ Excellent productI've enjoyed learning how to use this product..Version: 5.1
✓ The best calculator everThis is the best calculator that I have ever seen. Very reasonably priced and the best investment I have ever made. Please consider including context help with references to computing examples..Version: 4.2
✓ Better than my $200 calculatorTotally worth the money. I will be using this my whole life. The new step by step solutions is awesome. I will have to get used to the new UI, but it looks great. The amount of effort put into this calculator from parsing, calculation, display, to ideas is just perfect. I love that I get exact answers to problems that my $200 calculator can only approximate. Well done developers, seriously a work of art..Version: 5.5
✓ GoodThough like it, the new screen is not user friendly. Moreover, the memory keys can not be found easily..Version: 5.5.8
✓ Almost PerfectI've always loved all of the features and the ease of use. I particularly love the look and feel of the new update. Being able to see history of calculations on the screen is much better. However the numbers are as on the edge as possible so on an iPhone (with the slight border and rounded edges) half of the first number keyed in is not visible. It's manageable but also incredibly annoying particularly when it's a 1..Version: 5.5
✓ Very good!You have a choice. Either buy a calculator for $80-$100+ or some chump change for a comprehensive calculator. This team has created a largely inclusive app for just about any equation you could need. It's worth it. Plus too, if you mess up, you can back space to correct it. You can do that with the stock calculator iPhone has. You have to start over....Version: 4.6
✓ Awesome Calculator!An awesome tool for regular calculations and higher math! Can even do Summations (which I love soo much :) ), Integrals, Limits and even Imaginary Numbers!.Version: 4.3
✓ Awesome calculatorLove it, easy to use.Version: 4.6
✓ ExcellentVery technical calculator,different and easy to use..Version: 3.4
✓ CalculatorExcellent product, have used it for many many years..Version: 5.5.2
✓ Good ApplicationThis is arguably one of the best calculators on the App Store, however the interface could be made to be more approachable..Version: 5.1
✓ Suits me to a TDoes very well, simple to use and powerful..Version: 4.7.3
✓ Update ruined the app for meLike others have said— The upgrade made the numbers really small, and various buttons don’t work—I really noticed the buttons when I tried the conversion area. Almost nothing works there. The app is no longer intuitive. It’s like using an old scientific calculator that requires a teacher to use. When I checked out the “user manual” in the menu bar, I couldn’t find instructions for the converter. Disappointing to pay for something I use often and now doesn’t work for me..Version: 5.5
✓ Excellent appVery reliable and handy app for statistics that I used for.Version: 5.2
✓ Calculator: great productFinally delivers functionality I used to be get with my old physical scientific/programmable calculators. Great....Version: 4.6
✓ The new UI version no Torque convert?After updated to the newest version I just realized it is getting difficult to do the units convert, before we could just select unit to convert right now we have to actually type the units to do it, and do we missing the torque convert? I couldn’t find the unit with torque..Version: 5.5.2
✓ Great calculatorIt is a great calculator with many features and an clean aesthetic. I only wish that you made a simple/flatter icon so I could have this on my home screen..Version: 5.8.3
✓ UI is a bit strange but it works well enoughIve been using this app for few years now and still cannot get used to the UI - color scheme, buttons look like toy story, general layout of functionality, etc. If you set this aside it is a nice app with lots of features..Version: 5.6.2
✓ Good, could be betterGreat multipurpose calculator. Only knocked off a star because it was pestering me to rate every minute. Would also like to see some calculus functions introduced. Then I believe this app would be the best all round calculator..Version: 3.4
✓ Great appDoes everything I need and much more..Version: 4.3
✓ Upgrade from best to worstThe latest upgrade is a drastic decline in a quality calculator. Tap a number and it is not entered in to the formula. Instead, I have to hold a number in order for it to be included in the formula, most of the time. There seems to be new, and potentially exciting features, but the low functionality of entering numbers/symbols does not encourage me to explore them. Don’t use this calculator..Version: 5.5.8
✓ Greatest Scientific Calculator on App StoreThe user interface is as good as it’s going to get for a digital scientific calculator better than most analog ones. I’m giving 5 stars because it excels at providing smooth input of operations; however I’ve yet to use many other features, I still think it’s a very solid app. I’ve never written a review on the App Store before, alas here it is. This is the best bang for your buck calculator, I’m a student, for what it’s worth..Version: 5.6.3
✓ Great, only minor things missingDefinitely the best calculator app I’ve come across, only wish that it had fractions instead of the division operator and eventually the possibility to change the app icon....Version: 5.1
✓ Ruined by the updateIt was much better before the update.Version: 5.5.1
✓ Really good!It is worth every penny I invested in it. It is a bit complicated at first but you will quickly be able to understand how it works. It has a mod of features. 10/10.Version: 4.3.1
✓ Well DesignedStill familiarising with the app but it is well designed and intuitive..Version: 4.6
✓ An excellent calculatorDoes precisely what it says. Well worth the small price..Version: 3.4.5
✓ FernGreat calculator.Version: 5.5.1
✓ Proper calculator - works wellI tried a few calculators for the iPad which were frankly rubbish but this one is the business. The user interface is fine but could be slightly streamlined - but it’s worth the money..Version: 4.8.3
✓ Infinity calculatorVery pleased with the calculator, but there is very little help available which makes it really difficult to use the advanced features!.Version: 5.9.2
✓ Simply the best scientific calculatorI have used many scientific calculators on the apple market. This is by the far "The Best" scientific calculator on the Apple market. This scientific calculator application has many functions and features from basic, to complex calculations. Excellent for algebra, calculus, exponential equations, factorial and many more. I use this scientific calculator application frequently from every day uses to problematic equations. The only issue Is the help feature. The help is very vague on all key functions. That's it..Version: 4.6
✓ New update made it harder to use, but is still qualityI had used this calculator often due to its drastic improvements over purchasable individual calculators, to the point where this has become my go-to calculator. However, the new update has changed the layout in such a degree that I can no longer reliably use the graphing function and now have to use a third party method if I want q computer to quickly generate graphs for equations. The ability to scroll nicely between your previous answers is a godsend, including the ability to copy and paste, which is a massive improvement over any other calculator I have seen previously. I rarely if ever use the step-by-step function, but if I am feeling rather lazy I will use the algebraic solver which surprisingly works very well. I will continue to use this calculator as my main source of computations, but the graphing function needs significantly changed..Version: 5.6.3
✓ Bang on...!!!Lots of features, does what it says on the tin! Great app....Version: 4.7
✓ Awesome!A very good app!.Version: 4.7.3
✓ IntuitiveThis thing can do next to everything. I have an upgraded version and it is a lifesaver. This thing gave me a way to check my work in Linear Algebra, Physics, Calculus 1 & 2, EE classes and more. Its mobile user interface far surpasses desmos’s and can do far more. The navigation takes a second to get used to, but the amount of functions are totally worth it. Must have for engineers, and even better on iPad.Version: 5.9.6
✓ Excellent calculator !Been using It for months now. Replacement for a sci/eng calc (48s emulator). Does the job, lots of functions, friendlier interface. Just had to get used to non-RPN data entry....Version: 4.3
✓ Good, 1 suggestionGood calculator, very useful for uni and when I forget a scientific calculator. One small suggestion would be to add an option to prevent the screen from locking. It’s a little annoying when I’m making notes then have to unlock again and again..Version: 5.0
✓ Really bad new layoutThis version really sucks can’t do conversions anymore Need the old version back.Version: 5.5
✓ Hands down best Calculator app out there!Thank you for the iPhone X update! Also if anyone out there is looking for a good scientific calculator, you found it. Look no further, this is the best. Srsly, I tried them all, this is THE BEST. (Wolfram alpha and Desmos can do some neat things, but this is the easiest to use, most universal gadget you can find.) Just buy it, it's like half the price of a coffee nowadays....Version: 4.7
✓ Math Has Been ConqueredAs a dyslexic, I also have issues doing math in my head so of course I need a calculator for speed and accuracy. However, THIS is my calculator of choice out of the hundreds I have bought and tried. It covers everything from basic to advanced needs. and is even bundled with a great unit converter. They’ve also listened to my suggestion and added in number groupings. Lovely update, it also introduced tons of amazing new features!.Version: 5.5.4
✓ Great jobGreat job.Version: 5.6.6
✓ Bad OpticsThe new design is not good to use, the old design was much, much better, please change it..Version: 5.5
✓ Does what it says on the tinThis is just a really nice app to use. I have a large expensive graphing calculator, computers with the language R installed for maths and stats but also an iPhone so when I just need a calculator, this app comes out..Version: 3.3
✓ Top calculator on the App StoreTop calculator on the App Store.Version: 5.5
✓ This is a great productI tried most scientific calculators before buying this one. Well worth the money and does everything I want in an easy to use manner. Bill.Version: 5.5.8
✓ Finally the perfect calculator!I finally found the perfect calculator for my needs! It does everything I need! I really like the tap engine function too, which makes it more "real" on touch. Only thing that is annoying is the blue button on the down left corner that goes over the "zero"... I would love to remove it to have a cleaner view..Version: 4.6
