LoanCalc

won't launch, it just crashes

Doesn't work. Just crashes when launched.

If you need to calculate the payments on a simple interest loan, this is want (and all) the app does. Sometimes simple is good.

Crashes constantly

This actually helped me with a loan I currently have with one of the members of my family. Quick and easy! Highly recommended.

A little more context would be helpful (such as a Percent Sign on the Rate box. Also, a little plain looking, but gets right to what the app says it does.
