TI-Nspire™ CAS for Negative User Reviews

GoodThere's a lot of great functionality that you won't find elsewhere but it will need tweaked a lot from user feedback before its a top app. Unfortunately, with a company as big as TI and no updates since January, I'm concerned they'll just leave it and count on their niche market to recover their investment. It's a powerful app, but YOU WILL find something you either can't figure out or that doubles the time of your input because its so difficult to do..Version: 3.4.4

Incredibly difficult to figure outNot intuitive at all. Even after reading the 'manual' and multiple website help pages, I still can't figure this app out. I'm probably just too stupid to use it. The TI-83 and Voyage 200 both worked for me for years without any problems. I've written many programs over the years for both of those calculators, and also for the Mathematica and Maple Windows applications. So when I bought the TI-Nspire app, I was expecting either a graphing calculator app (like the TI-83 or Voyage 200) or a math program (like Mathematica or a Maple). Unfortunately this app is neither. In fact, I'm still not sure what this app is. :-(.Version: 4.4.0

CrashGreat calculator but it crashes when it is run on iPad Pro 11-inch.Version: 4.5.0

TerribleMade me fail my math test. Lame af.Version: 4.5.0

MrDespite the high price tag, seeing the app was by Ti I got very excited. I was particularly looking forward to quality graphing capabilities. In short I'm disappointed, particularly with the 3D graphing as spherical and cylindrical expressions aren't allowed. In fact graphs can only be input in function form i.e. subject = expression. Graphing two equal expressions, often extremely convenient, isn't an option in this app. I was pleasantly surprised with the geometric construction facilities but that's not what I got the app for. Also the nifty ability to change 2D polynomials and trig functions by 'physically' manipulating their graphs while impressive isn't very useful for me and isn't applicable to polar expressions. To summarise this app is quantity over quality, clunky as opposed to slick and intuitive and does't really take full advantage of a tablets abilities. However there are lots of applications to utilise so three stars..Version: 3.4.1

Where is the financial solver?This is a great app but needs work. Where is the finance solver?.Version: 4.5.0

Interface needs work, but great CAS system.I have the TI-Nspire CX II CAS handheld. However, I figured that I would get this app in case it ever got lost or stolen. For $30 USD, I do not recommend this app until Texas Instruments updates it to support modern iPadOS multitasking. (The ability to have this app open with another at the same time) It makes it an absolute pain to use as I have to constantly switch back between my notes app where my math work is and the CAS, sometimes multiple times during the same problem. I strongly prefer using the physical handheld device over this app..Version: 5.2.1

Doesn’t work on iOS 13On iOS 13 (or is that iPadOS 13?) the app crashes as soon as you tap on the table of contents to move off Page 1.1 of any workbook..Version: 5.1.1

AkKeeps crashing please fix.Version: 4.3.1

Great version of the calculator, just missing iCloud Drive supportIt would be a much better solution if it supported iCloud Drive in addition to DropBox as I will never use DropBox and iTunes sharing has been removed. Otherwise I am impressed with the provided functionality. The greatest thing about the calculator is that it takes advantage of the iPad rather than attempting to mimic the interface of the actual calculator. This alone makes this version much better than the actual calculator. Too bad the calculator does not take advantage of the full screen size..Version: 5.2.1

Clumsy interface, doesn't play well with google driveThe math is spectacular, but the lack of attention paid to getting stored programs into the program harm its reputation.Version: 4.1.1

Doesn’t look like real NspireThis makes it nard to learn as the videos on the web are so different. Also it only works in when the ipad is held sideways, while the real calculator is held upright. Took 5 minutes to discover that one must click “New” to even see anything that looked like a calculator. So far I am sorry that I spent the $30..Version: 4.5.0

Doesn't fully support iOSThis programs does not fully support iOS despite its significant cost. Hopefully, they change this in the future..Version: 4.4.0

Tremendously Difficult to FollowUnable to get correct documentation on very expensive application.Version: 5.1.4

Great but...There’s still no support for the ipad pro 2018.Version: 5.1.1

Powerful, but hard to useAs a first-year college student studying engineering, I use math apps every day on my iPad. I was about to buy the TiNspire (or however they spell it) CAS graphing calculator, but then I saw this app, so I thought I'd give the app a try before purchasing a $130 calculator. For the price that I paid, this app is worth it. It does almost everything that I need it to do. However, the app isn't very easy to use. The 3D graphing is the part that I need most, and it is unfortunately the hardest part of the app to use efficiently. It only allows me to enter equations in the z(x,y)= format, and I was hoping that it would allow me to enter equations in formats such as x^2+y^2+z^2=1 (the equation for a sphere). Despite my disappointment in the app's 3D graphing capabilities, it is a very powerful app nonetheless and will help me when I get stuck on math homework. Additional note: Unfortunately, the app's power may be a little too much for my iPad to handle, as the app has crashed occasionally for me. I'm using an iPad 3. If the crashing is fixed and the 3D graphing is improved, this app would deserve 5 stars..Version: 3.4.1

CrashesCrashes frequently please fix your app.Version: 4.5.0

Absolutely hate the interfaceWhy can't they have the calculator on the side like in the windows version? This app was such a waste of money. I purchased it to show my students how to use their CAS, however, it's pointless as nothing is the same as on their CAS... I need it to be the same... Take a leaf out of CASIOs classpad version!!! So much better!.Version: 4.5.0

Request for update/feature or fix for bugsI like the app very much, however, there is this little problem that's bugging me and slowing me down. Every time I switch apps, I have to re-open the calculation sheet. Can you fix this problem so that when you open the calculator it is where you left it?.Version: 4.5.0

TI for teachersDon’t download this app if you are a teacher b/c it cannot fill that role. Otherwise it works fine as an over-priced calculator..Version: 5.0.0

TerribleObviously TI do not value user experience. The previous interface change with iOS 7 was bad enough, this is just unbearable. How do they expect us to clearly make out the thin icons on he very lightly coloured blue background? BEWARE THIS UPDATE..Version: 3.11.0

Frequent crashingThe app crashes within 2 minutes of use. Very frustrating when typing in complex long equations just to have it crash and erase my progress. This app would’ve been 5 stars if it didn’t crash. But with it crashing this often it’s a complete waste of time..Version: 4.5.0

Difficile d’ouverture à partir de l’cranL application ne s’ouvre pas correctement Gros problème de fonctionnalité.Version: 6.0.0

Constantly reading clipboardWhy an app for a calculator needs constant access to my clipboard is beyond me and a massive invasion of privacy..Version: 5.2.1

Crashes on startupThe app crashes if you try to open anything, so infortunately it is completely unusable. Hopefully they can fix it..Version: 5.2.1

No Multitasking SupportLet’s be honest: I have a calculator on my iPad to do homework on my iPad. To do this, I need two windows so that I can both see my work and do the calculations. You can’t do that with this app. Sure, you can overlay another app on top of it, but when you do that, the in-app keyboard crashes, making the app totally useless. It’s a great calculator, but without the ability to have two windows, it’s pretty useless. I requested a refund from apple, but they won’t grant it..Version: 4.5.0

Keeps crashingCrashes when I try to highlight the previous line. Frustrating..Version: 4.3.1

Great! BUTThis app is amazing for calculations, creating graphs, solving systems etc... BUT it keeps crashing! It is very annoying when I'm in the middle of a complex problem and the application crashes. Please fix..Version: 4.5.0

Updating my reviewA while ago I wrote a much more positive review of this app, quite a long time ago. The app works alright, it has all of the features of the TI-Nspire calculator. Although, none of the features that I recommended have been added and they are getting much more needed as time goes by. The app still doesn't have split view support, which makes this pretty much unusable since I use split view constantly. Along with that, this app still hasn't been updated to use the 12.9 inch iPad Pro screen, which just makes everything more difficult to do. Everything from typing to navigating the UI could be so much easier if you made use of the larger screen. I'm still hoping that one day we will get these features and when that day comes this app would easily be 5 stars. But as it is there is just so much that needs to be added..Version: 4.3.2

Awesome - with a fatal flaw?I had been migrating my engineering work from a beloved TI V200 (essentially a TI 89 Titanium with a QWERTY keyboard) to this app, but now wonder if it was premature. The latest upgrade appears to have erased the several dozen user-defined variables I had entered. If this is to be expected with each future upgrade, then I shall have to go back to the V200. I was hoping to not have to carry around another gadget. Maybe another app will offer the units feature with persistent user-defined variables, or TI will address this issue? Otherwise, this app was the closest functional match to the V200, and the only one with the same ease of units conversion..Version: 3.10.0

Good functionality with poor interfaceIt would have been nice if the user interface was the same as the actual calculator, but for some bizarre reason, the developer chose to make something that bears absolutely no resemblance to the TI Nspire, or any other calculator for that matter. It pretty much uses a glorified iPad popup keyboard as the main input, which, to put it mildly, is very clumsy. Since part of the purpose of this app is to be able to use and learn the calculator when you don’t have it with you, it makes no sense to have designed the app the way they did. What is really odd, is that the in PC version of this app the interface is almost exactly the same as the Nspire, so why they didn’t do that here is beyond me. Despite all that, It’s a powerful calculator and it’s great having a CAS on the iPad. Overall, it is a great tool despite the frustratingly awkward way you have to work with it..Version: 4.5.0
