HP Prime Pro

There is no vibration for any key, so it is difficult to recognize whether the key is actually pressed. Please fix this. Upd. —— After using it couple of months, I think that the app is okay even without the key vibration functions.

In CAS mode do integrate from 0 to pi 1/sqrt(1-x^5) dx application crushes and after restart i see no expression i entered. On real device on the same example i see the warning, then calculation continues an does normal complex result

I do not recommend anybody to buy this graphic calculator. I have tried to use it for 3 months and it still crashes. Waste of money. The real thing, HP Prime Graphing calculator, is probably an excellent product, but the IOS version is very badly done software. I have IOS 12.1.2, iPhone SE. Buy instead following calculators which I use. FxMath Solver, Desmos and PocketCAS.

Awsomely powerful kit to be carrying around in your pocket. Works like a charm.

... Works fine after reset!

The HP Prime Graphing Calculator is a VERY capable calculator, problem solver, explorer and educator. Some minor bugs in version 1.0 but it is still a really nicely implemented app and a very useful calculator only surpassed by the physical device.

Over all I love the representation of the calculator, but that makes it rather annoying to attempt to program on the calculator without the external keyboard. That was one of the biggest drawbacks to the actual calculator. If HP would simply use the native keyboard or alternative keyboard it would be more useful. Update: It does appear that HP is leaving the calculator market as they have sold the business to Royal Consumer. It appears that Royal is also not interested in staying in the market and has transferred the application to Moravia. It appears that the demise of the HP calculator is complete.

The calculator works as it should and I haven’t had any issues so far. The app however scales its gui to fill the screen and it doesn’t look sharp. I would give it 5 stars if they improved this.The app is great.

I’m using a real HP Prime and this iOS version is more convenient and durable (the keys on my real calculator is kind of broken after 3 years). My real calculator is a G2 hardware version. Somehow it can’t properly plot Y=X^(1/3) in Advanced Graphing (X<0 is somehow not defined), but this iOS emulator and PC/Mac emulator are both correct with the domain. This is an emulator, but it’s kind of over emulated. Why not add system 26 keys keyboard support? It will be a lot easier to type in commands. Besides, I’m writing this review in 2024. The latest firmware version is released on 04.13.2023, but in the emulator it’s only 05.05.2021 version. Other than these it’s still a good emulator. It solves some integrals like ∫(1/(x^3-1),x,0,∞) that Texas Instruments and even Mathematica couldn’t.
