Seems the HP Prime calculator has become abandonware on iOS. Crash problems remain for months/years that have been fixed (or don’t exist) on the actual calculator. Example from user manual: exp2trig(exp(i*x)). Crashes every time. Many other examples as noted in iOS store page user comments. Much frustration & low ratings. Paid $25. Expected better from HP.
Any comments from HP?

Hi!, @Kcnicho :
Try, Reset, the virtual Calculator and then, put in CAS Mode, as ...
Note : The result, is OK.
From User Guide ...
Returns an expression with complex exponentials rewritten in terms of sine and cosine. exp2trig(Expr)
Example: exp2trig(exp(i*x)) gives cos(x)+(i)*sin(x)

Thank you for the suggestion.
It appears your screen shots are from the PC calculator emulator. Unfortunately, the iOS version has no similar menu with a reset option. I'll try uninstalling and re-installing.
iOS calculator was in CAS mode. Just tried again and it instantly crashes. Tried on an actual physical HP Prime I own, and it gives the correct results.
Just seems that the iOS version (even though fairly pricey at $25 for the "pro" version) gets little attention as far as updates and fixing problems. Very sad, as it could easily be THE BEST virtual calculator in the app market.

Thank you Cheron-Z
I have tried deleting the HP Prime (pro) app from my iPad, and re-loading it from scratch, using all default settings. Still immediately crashes when I try to calculate exp2trig(e^i*x) in CAS mode. Verified this works on "real" calculator, as well as the PC emulator.
using iPad Pro 12.9 inch, 2nd generation, iOS version 12.1.3
Thanks for your help

Just checking back in. Haven't seen any activity recently.
Any updates? Is the iOS crashing issue being worked on, or is it even "in the queue"?
I've seen a few other posts on other forums with the same issues, so I'm pretty sure it's not just me.
Please let us know how things are going out there. Active communication with your customers goes a long way.

I use real HP Prime at home, Android HP Prime Pro on my phone with android 5.1, IOS HP Prime on iPad Pro 12.9 with latest IOS, and windows Virtual HP Prime.
On my own I have had problems with Android version of HP Prime, but with the latest update the problem gone.
But on iPad the problems in CAS still persists. Any operation in CAS mode can make application to crash.
One of my simpliest example is as follows:
right after fully reinstalling HP Prime Pro on iPad
x- unassigned variable.
solve((pi-x)^2=1,x) crashes application
All other platforms emulators and real HP Prime do the right answer +-1/pi
It looks like the latest updates of IOS do not taken into account and IOS version of HP Prime Pro is simply incompatibe with the latest versions of IOS. I think this can be verifyed by setting the IOS HP Prime Pro on device with old IOS version and check the same tests there. Unfortunately I do not have any device with the old IOS onboard. If anyone can test this please reply.
