Mis leading

My search was for a HP BA-II like the one I purchased for my iPad & iPhone. This is NOT a HP it is phony junk. Deceptive search. !5 dollars wasted.

One Flaw/Feature Causes Problems

The app seems fine otherwise, but not being able to hit “enter/return” to receive the answer is unintuitive to me. Also, everytime I close the app it forgets all the data/settings, such as the number of decimals to use, etc.

It would also be nice to be able to resize the application window, and have the app icons adjust accordingly.

These changes would definitely make it a 5-star app.

It makes math errors

When you use the ammortization worksheet function, it does not correctly calculate interest and principal information.

In addition, you have to click the numbers, rather than typing them, but the MUCH bigger concern is the fact that this calculator does bad math.

For example, if you borrow $150,000 on a monthly mortgage at 7% for 30 years, how much interest will you have paid? I don't know because this calculator thinks it is only $810. Ok, so I actually know, because my TIBAII+ gives me the correct answer. Thank goodness my TI got it right even if Vicinno's app did not.
