Pay Off Debt: Debt Calculator

So I absolutely love this app. I tried several and I just wanted something simple to write out my debts that I owe as I am doing the snowball method from Dave Ramsey, and this app I can easily write them all out and see them easily. I love opening it and have it quickly accessible to remind myself to stay on track and keep my goals in sight. Super easy to use and again I love the simplicity.

Too basic did not give much help

The app requires a payment amount, but it can fluctuate with line of credit and credit cards depending on balance. I tried putting it high payment amounts and minimum amounts but it kept giving me an error. It should either let u put in that it is based on balance or skip it and calculate it based on the interest and balance.
