I’ve used an HP 12C for 20 years to calculate amortization payments for loans. This app either shuts off completely or gives an error 5, 9 out of 10 tries of entering the data and hitting the pmt key. How can the calculator be so great and the app be such junk?!

This app s totally useless! Hit clear, it crashes. Hit PMT, PV and it crashes. I wouldn’t keep this app on my phone even if it was free!

Won’t do simple financial calculations. Constant crashes. Provides incorrect answers. Can’t believe hp would put something this flawed on the market. Very disappointed!!

Can’t believe this expensive app is still without updates, OMG I’m really disappointed... more than 6 months not working

After updating my iPhone and iPad to iOS 14 the app does not work for basic payment calculations and the app closes randomly. I’ve owned both the 12C and the 12C Platinum physical calculators in the past and I am now forced to use someone else’s app. HP please update your app!

You can’t clear or it crashes. You can’t do mortgages because you get Error 5. A very expensive waste of hard drive space.

This app was supposedly created by HP. I would love to use my phone and/or iPad with the 12C app rather than have to carry around a separate calculator. Whenever I open the app, it immediately crashes. Then again, then again. Usually after the second or third launch, the app will actually work. It’s incredibly frustrating and it makes the user look incompetent in front of a client. The 12C is a professional tool and it needs to function properly.

Jan 2021-This app is almost useless now. Crash and error or so frequent. I understand iOS updates probably interfere somewhat but this is ridiculous. Error 5 and crashes.

everytime i open the app and try to do a problem, at the end of the problem the app just shuts down & exits out. does it on my iPad and iPhone. Very pathetic considering you pay for this app. DO NOT PURCHASE.

I have been using an Hp 12C for 25 years. I was excited to download the calculator to my phone. I’ve only had the app a few days but it is glitchy as heck. I can’t calculate anything without it closing out of the app. I’ve uninstalled the app and reinstalled and that doesn’t seem to fix the problem.
