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.

It does what you would expect it to. I would possibly add the ability to remember what you last entered.

Put in loan total, # of years, and interest rate, and it tells you the loan payment. Would be nice for number nerds like me if it gave more details like total interest paid, and if it had more options like allowing me to pay additional principal per month and calculating the effect that has on the loan.
