Help!!!!

I bought this app because I have been looking for an app that is similar to the HP 17b. Man was I wrong. I have messed with this app for an hour and can not get the financial calculator portion of this app to match my HP 17b.

Does anyone know where to find a user friendly app that has true financial calculator capability?

Everything I find simple calculates a loan payment or the calculations are wrong.
