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.

I just want to easily connect this to my connectivity kit and move over my backup from my actual calculator.

Can’t believe this is still designed for the old iPhones with buttons. It’s hard to and everything is too small. If it was updated to fit the new iPhones it could be zoomed in more making it much easier to see.

NEEDS UPDATING. BADLY. A vertical mode with responsive resizing for iPad Pro multitasking is MISSING. BRING IT UP TO SPEED. Allow for more streamlined UI and connectivity tutorials.

Please update the app to be optimized for iPhone 11 Pro Max phone.

HP Prime is the best calculator out there and runs circles around anything from TI if you know how to use it. This updates reflects the 5/5/2021 firmware update of the real calculator. This app faithfully replicates the calculator’s functionality. The only missing feature is the ability to synchronize programs with the real calculator or the pc emulator that is probably related to iOS sandboxing restrictions.

How do you load . hpprgm files into the app prime pro?

I did a calculation producing ~2.64. I have the angle setting to degree. I used the ATAN function with Ans/10 as the argument and the calculator gave the answer as ~2.64e-02 which is clearly wrong. So I repeated with ATAN(2.64/10) and got the answer 14.81º which I checked using a handheld calculator.

Just downloaded pro version. App is stuck in the language mode, shifting between the various languages. What do I do?????
