AllRPNCalc Calculator for Positive User Reviews
✓ Must have RPNI grew up using RPN, and have no interest in ever learning algebraic entry, so this app is a lifesaver..Version: 4.0

✓ Superb In Every Way!I missed having an HP 12C emulator on the iPhone (had one on my Palm). Some how I missed this calculator when looking in the App Store and instead purchased one of the other 12 C emulators. It was ok, but the keys were small, it was slow loading and there was a delay in pressing the key and seeing the response. Then while browsing the App Store one day I found AllRPNCalc for a much cheaper price. It is the best calculator app for the iPhone in my opinion - the keys are large and clear, the display is wonderful. I love the red and green coding used in the display. The key click sound is not annoying as it is on some of the other calculators. Unlike other iPhone calculators this one is fast and accurate. Plus, besides getting a financial calculator that is true to my old 12C, it includes features from other HP RPN calculators from the past. Buy this calculator, you will be very happy. It is reasonably priced, takes up very little memory and the developer has proven to be very fast at fixing bugs..Version: 0
✓ Still the best RPN Calculator app out there!I grew up with an HP 35 and moved to the 11c. This app is superior to HP. So much more capability and usable functions. I have been using this RPN calculator since it came out many years ago and I love it! Great for engineering calculations, conversions and financial. This is a great product for a die hard engineer that grew up on RPN! Thanks for keeping it going!.Version: 4.2
✓ Still the best RPN calculatorVersion 3 has added features; it is just as stable--perfectly stable; never crashes, no problems--as the earlier versions. A great application in every way and a bargain compared to any other RPN calculator in the App Store or stand-alone..Version: 0
✓ Comprehensive and easy to useHave been using RPN calculators since mid 70's. This is thorough, seems complete, straight forward, logical, and easy to use..Version: 4.0
✓ RPNUse it all the time. Excellent app..Version: 4.0
✓ Great RPN calculator!Beautifully implemented, with all the usual functions and many unexpected bonuses (e.g., currency conversions, 12c-like financial functions, stat plots with regression lines, etc.).Version: 4.2
✓ Love this appReally nice if you’re used to RPN calculators. I use it daily..Version: 4.2

✓ It's like having my HP back in my handLive it. RON logic is the way to go..Version: 4.0
✓ UserI like this implementation of RPN. Would be nice if there were a native iPad version — that somehow took advantage of the larger screen..Version: 4.2
✓ Hp-12c +++++For those of us who grew up using Reverse Polish Notation, RPN is built into our hand. This little calculator app is easy to use, and has many more features than the HP-12C. Weight and volume conversion is often really useful, and it's easy here. Currency conversion! Get updated conversion rates with a couple taps. I've been using this great app for about 7 generations of iPhones..Version: 4.2
✓ Excellent app.If you are used to RPN calculators, this is the app for you. I used an HP 48G for years and struggled with online calculators. This app. Was an answer to my concerns. Works like a 48G..Version: 4.0
✓ Outstanding RPN calculator...If you like HP calculators, this app should serve you well. I have been using this calculator for years, and it remains one of my all time favorites. It takes a successful HP calc and adds several useful features: unit conversions, currency exchange rates. I also value its ability to perform scientific and financial calculations. I have tried and used more than 20 calculator apps. Some do offer features not in this one. However, it is in my top two calculator apps. So glad the developer has updated this app to be compatible with current iOS versions. Hope other legacy app developers will do the same. The fear of losing this one kept me from being willing to update to the latest iOS. UPDATE: Been using this great app for years, and it never lets me down! Kudos to the developers who have kept this app working throughout all the many iOS changes by Apple..Version: 4.2
✓ Excellent CalculatorOnce you’ve learned RPN, you can never go back. This calculator is very easy to use and super reliable. If you know RPN, you’ll be very happy. If you want to learn, this calculator is a great reason to make the jump..Version: 4.2
✓ Go-To CalculatorA super all-in-one tool. I’ve used it every day for years. The conversion tool is especially helpful..Version: 4.2
✓ Great app - just what I neededThis does everything well, providing you do not want graphing. great finance stats and conversions. easy to use the best app I have bought..Version: 4.0
✓ Great RPN calculator!I used to work for the HP calculator division that pioneered RPN. Trust me. This is beyond a full featured RPN machine. Well thought out. Great job! Each version is even better than last. Now at v4.1. Very happy customer..Version: 4.2
✓ EXCELLENT calculator, constructive feedback belowI was looking for an HP32 equivalent, but found that allRPNCalc was better than the real HP calc (except no programmability). The keys are good size, the response is fast, trig accuracy seems good (tan(pi)), register display is nice extra not found on real calc, and on-line update of currency conversion rates are unique to networked calculator. However, some of the currency conversions are inverted wrt arrow keys, e.g. Japanese Yen or Swiss Franc to US dollar. Some of the common conversion rates used for news are opposites, and maybe the online feature used here is not taking that into account. Please fix this. Also, dedicated x^3 and cube-root-x is not necessary given y^x and xth-root-y. 2 limited programmable keys would have been nice. I always use dB's, so 10*log10(x) and 10^(x/10) would have been my choice there. Thanks for a great app..Version: 0
✓ AllrpncalcVery excellent rpb calculator. highly recommended..Version: 4.2
✓ AllRPNCalc is best one out thereI've tried most of the HP calcs for iphone. This is the most intuitive interface and includes super helpful conversions, including currencies. Love it. Thanks for updating!!.Version: 4.2
✓ Love itI've been using my HP15C and RPN since longer than my current students have been on the planet. This was one of the very first apps I purchased when I got my phone a few years back. Great app. Thanks to the developer for the free update. Highly recommended..Version: 4.0
✓ Best and most comprehensive financial calculator on the marketHighly recommend.Version: 4.2
✓ Awesome RPN calcI’ve been using this app for quite a while and love it!! Thanks!.Version: 4.2
✓ Great RPN Calc!Calculations are spot-on and this developer has been kind enough to provide free updates for many years now... Which makes it well worth buying. I've tried others and I still like this one the best. Very easy to use yet it has the depth and breadth you'd expect. I use it frequently for mortgage calculations and amortizations..Version: 4.2
✓ Best oneDoes it all, excellent interface and operations.Version: 4.2
✓ Super duper awesome in all the right waysComprehensive features, intuitive settings, and a natural user interface. Well thought out and developed calculator. Thank you!.Version: 4.2
✓ Best Calculator AppI was so relieved when allRPN updated to 64bit. It's one of my most used apps, there is not a better straightforward calculator I have seen, and I went through a few. It handles everything that can be thrown at it. Initially it took some time to get used to RPN, but now it is second nature. Can't recommend this app enough.Version: 4.2
✓ AllRPNCalc - the bestI have bought very few apps for my phone. The purchase of allRPNCalc is the exception. I spent a few dollars on this several years ago and it is the best use of money for an accessory ever. A powerful RPN calculator, that does everything I need and more. It is regularly updated to keep it in sync with all the updates iOS undergoes. I highly recommend this app to anyone that needs an RPN calculator. You will not find better..Version: 4.2
✓ I have bought several, but I use thisI like RPN calculators, own three real HPs (17B, 32S, 49G) and own a few emulators and others for the iPhone including well-reputed general purpose or scientific ones. With experience, this one currently outclasses the others of its type. It is not a clone of any particular commercial calculator but it has a broad range of functions, is easy enough to use and is very flexible. This is an economical, efficient, general purpose RPN calculator and I recommend it in that class..Version: 0
✓ Great RPN calculatorI use it all the time!.Version: 4.2
✓ Love itExcellent app. So convenient. I don't have to carry my HP17 anymore.Version: 4.0
✓ Works great, exceptI’ve been using this app for many years and find it great as a financial and general calculator. I calculate loan payments routinely. It has always worked great. However , recently I looked at an amortization chart and could not exit the chart. Stopping and restarting the app did not clear it. I had to restart iOS to get back to the main page. Please fix!.Version: 4.2
✓ RPN RulesRPN rules and this is the calculator to do the job.Version: 4.2
✓ Great rpn calculatorCouldn’t do without it.Version: 4.2
✓ Great calculator !I’ve been using this app for years, ever since I lost my HP41. I only got it as a temp, but it quickly became full time. If you like using RON, you can’t beat it. Plus, it’s got a lot of features my old HP didn’t. I find the conversions very helpful (cu yds - cu in, km - mi, etc).Version: 4.2
✓ Very very good Calculator(14-Sep-08) If you prefer the RPN entry method you will like this calculator. The keyboard layout makes sense and the functions are well organized into separate menus. Switching display modes is simple, for example, to select "4 decimal places fixed" simply press the display mode indicator at the upper left until it reads "Fix" and then press "4." You can view the contents of all registers (except the triangle solver) via the help menu icon. Key clicks can be turned on or off for quiet locations. The unit converter is intuitive, making good use of the iPhone/iTouch UI methods. And... the factorial (gamma) function operates correctly, with "-0.5 n!" giving the proper result... many calculators get it wrong or throw an error. This app gets nearly everything right. Some minor cleanup of the look (move the help button to top center and extend the static number & four-function keys) and a 64-bit capability in the programmer's functions will merit a perfect 5 stars, but really: for a first release this is superb..Version: 0
✓ Don't leave home without itI consider the program of the MOST valuable ones on my iPhone...and wouldn't leave home without it. My wife doesn't understand why I need RPN for routine math, not to mention financial calculations, trig functions and statistics...but I do! When a recent "update" glitch, now resolved, left me without the program for several weeks, I realized how much I missed it, as I found myself trying to open it several times a day. Ultimately, getting it again operative, once I found the instructions on the developer's website, proved ridiculously quick and easy. A particularly nice feature for the Financial section is its nearly automatic generation of a full amortization or depreciation schedule. The one feature I would like to see in the next version would be operation in both the current vertical but also, the horizontal mode, the latter the way one uses the fabled HP11C and HP12C, which I have in the hardwired versions, but which I no longer carry, as allRPNCalc makes them superfluous, rather like a DC-3 in an Airbus 380 era..Version: 0
✓ Best RPN CalcI grew up using the HP42s, which I loved. I have the phone app for the HP42 also but I use this app as my go to app. Easy to use with all of what I need within a few strokes..Version: 4.2
✓ Better than HP!Didn’t think I’d ever say this, but this calculator is better than HP’s. Of course, it doesn’t have all the cool stuff built into a 15, for example, but for what it does it’s very thoughtfully designed and works conveniently well. I also like all the trivia and background sprinkled throughout the documentation, FAQ, etc. Not only is this a very well-designed and useful calculator, but it also educates you on some of the history and science behind implementing floating point math in a binary machine. I’m a very happy customer..Version: 4.2
✓ One of the bestI looked around for quite a while for a good RPN calculator. Then I found this one! I have it on my first page of apps. It's my goto calculator. Very satisfied..Version: 4.0
✓ Best RPN calculatorThank you for the update. The look of the interface is beautifully done and the app will live on! Been using this app for years and it was breaking my heart that it might not survive the next iOS update. I think all of the changes are excellent, and yet the look and feel of the calculator are maintained. Thank you, and keep up the great work..Version: 4.0
✓ Love itThis calculator is a real buy at this price. I love all the choices and the ability to get foreign currency quotes. I used to use RPN notation and then lost my HP calculator. This machine is really slick. I couldn't live without it..Version: 4.0
✓ Best ever calculatorLove it. Use it everyday. Get it now if you like RPN.Version: 4.0
✓ AllRPNcalcI bought this about 6 mths ago, and use it every day. Reverse Polish input becomes second nature, it has heaps of functions, and I like the 18 memories available. It is the most useful calculator I have bought. The latest upgrade caused the app to fail to load and this was a big problem because I needed it for end of month financial work. I sent an email to the developer round midnight and had a reply and a four minute fix in about one hour! That is REAL service. Get this app! Great calculator and backed up by real people with real concern for your needs. Maximum number of stars awarded here. Thank you..Version: 0
✓ Great program!This is a great RPN app! It works very well and the developer support is exemplary! I had an issue with iOS 11 update and the response to my inquiry was swift and simple. Way more than I’d expected for a $6.00 application. Others should emulate this fine example! Well done Mr. Brock, thank you..Version: 4.2
✓ Latest version still BEST CalcGreat app with the feel and reliability of my old HPs. I still go to this calculator first because it is fast and reliable and easily handles complicated calcs. Latest OS updates are great too..Version: 4.2
✓ My "go-to" calculator!This has been my calculator since I first switched from a Palm TX to an iPhone (long, sad story). I have bought a couple of HP emulators which I still use when nostalgia gets the better of me, but this calculator is still the one I use on a daily basis - it's got it all and goes beyond anything my beloved HPs could possibly deliver, even with all the program packs on the planet… This latest version is (on reflection) an improvement. I'm finding myself miskeying far less often (always a problem with glass keyboards), and the few changes actually work quite well once you get used to them. If you want a do-it-all RPN calculator, give this one a try. It's well worth it. ( Now 25/5/2018 and I wouldn't change a word of the above review!) (Now 3/8/2019 and I wouldn’t be without this app!).Version: 4.2
✓ The best!!Hands down, the best calculator anywhere. If you’ve ever used an RPN calculator this is the one you need. If you haven’t used an RPN calculator, you should learn so you can use this one. Absolutely the best..Version: 4.2
✓ Had it since the original. Use it. Love it.This has been one of my most used apps over the years. It's had very few if any updates - because it hasn't needed them, until this latest OS release. I was sad to see a notification that this RPN calc wouldn't work anymore. I'm now happy that this new updated version came out. My only suggestions are to make the stack longer and to add 'mils' in the conversions..Version: 4.0
✓ ExcellentBeen using for years. All the functionality plus more. Never a crash..Version: 4.2
✓ Beautiful UpgradeThanks for upgrading this highly useful app and making it even better. The graphics are beautifully crisp and the the added ? key improves functionality even more. It was a loss when the calculators that ran these apps disappeared and we are fortunate to have someone who is obviously passionate about keeping this legacy alive in the new digital era. Well done..Version: 4.0
✓ AwesomeBest smartphone calculator out there!.Version: 4.2
