I have latest ios8.1.3 on iPhone 5C. When I open this app it is frozen. For a paid app I expect better performance than this. Worked perfectly (apart from annoying key stroke noises) on my 4S.
Please fix HP????
Calculations are correct
I can’t understand why no one (even HP) have corrected the review by gride286, about 3 years ago (2016) titled “INCORRECT CALCULC...” gride286’s problem is that on one calculator, the PMT was calculated assuming that the payment was made at the start of the period (g>BEG), and on the other Calculator the payment was made at the end of the period (g>END>). This choice is hard to miss as a small “BEGIN” shows in the screen. Generally, such as a lease payment, payments are made at the end of the period, but some financial transactions such as receiving an Annuity, the payment might be made at the beginning of the period. Otherwise, a great app, exactly like the physical 12C I have had and used for 30 years.
Update fixes long standing issues
Thanks for the update HP! Now the vibrate on key press is an actual haptic feedback instead of old style vibrate, so I’ve re-enabled Key Vibrate in System Settings -> HP 12CP, and the app now correctly loads the previous state.
Looks like it’s introduced another bug though where the app can crash when you press CLx... I’m sure you’re getting the crash reports so hopefully this will be fixed soon :)
Thanks again! The only calculator app I use on my iPhone when I don’t have my actual 12C with me...
