App Continually Crashes – HP 12C Platinum Calculator Review

I have used this app for years. This app is not being properly updated by the developer; this product crashes when making amortization calculations. My iPhone VR and now 12 have experienced the same issues; the developer’s web site does not provide support or even an option for communication relating to this app. Assuming there are compatibility issues relating to an Apple update that was never addressed. I have tried everything from reinstalling the app It used to be good!
