HP 12C Platinum Calculator

Crashes or shows error 5 after TVM calculations on both iPhone and iPad. Was good before. Deleting and reloading app corrects this !

Help the app no longer works and the calculator crashes when I use it. Please please fix

It works well, I had to reset it first because of an error and crashes, and now I have a fantastic 12c on my phone and tablet. Thanks, devs.

I love my HP-12CP app but the latest update is causing it to crash every time I tap the clx key. If I do a reset it’s fixed again for a while but starts crashing again later. Please investigate and fix. Thanks

Don’t know why but since last year (2019) the app closes every time I try to clear the cache. How can I be refund once it’s not working?

Was my go to calculator until this. Please get it working again (iOS 13.3.1)

I purchased this HP12c for GBP11.99 but a different basic version has been uploaded on my iPhone....disappointed, feel cheated 😁

I have been a long term user of HP financial calculators. I also purchased a cheaper app from a competitor, but I wanted the real 12c version from HP. I bought it, but I regret it because of the obnoxiously loud clicking noise on each key stroke. I just don't understand why. The original hardware did not make any noise, so why did the decide the app needed it. It makes it unusable.

Very pleased with purchase of the HP12c but please tell me how to turn off the key 'click' it is too noisy and distracting! Would also appreciate a graphics update for compatibility with the iPhone retina display.

It is a great app apart from one thing: how can the sound clicks be turned off?
