Crashes frequently. The CLx button, when in portrait mode, will crash the app every time.

This is the worst app I’ve ever paid for. I’d like to get my money back

App opens but touching any button causes app to immediately close.

Just annoying. The 15C app doesn’t crash like this, so I rarely use the 12c anymore. Please fix this.

Do not buy, errors in TVM calculations

Constantly crashes. Had to delete app and reinstall. Works for a few calculations and then app freezes or exits and you have to start all over again. DO NOT BUY this app!!

Errors when trying to calculate a mortgage payment. Emulation does not work like the financial calculator. Yes, I compared it to my HP12C Platinum. It would have been nice to also have a working app on my phone. Don’t spend money on this app. I am very disappointed and dissatisfied.

This app fails when calculating payments on a mortgage. I works the first time after download from the App Store, then fails with Error 5 after this. Very poorly done and no support.

App keeps crashing. Issues with loan calculations. Don’t waste your money on this, not reliable.

When I originally purchased this App, it ran flawlessly. With each iOS update, this App’s functionality deteriorated! Now, whenever I use the “CLx” button the App crashes. To add insult to injury, I cannot even run basic amortization functions or “CFo” functions. In the world of commercial real estate, when Excel is unavailable, the 12C is necessary for quick CRE calcs. I am appalled that HP is NOT supporting this App yet are forcing 12C loyalists to purchase the other 12C Gold App for another $14.99. I demand to be refunded for my original purchase!!
