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.

Great app but recent update causes crashes

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

TVM not working after latest iOS update

Crashes or shows error 5 after TVM calculations on both iPhone and iPad. Was good before.

Deleting and reloading app corrects this !
