Save $$$$ app for iPhone and iPad

Use this app to determine a savings plan in one of two ways: by computing how much will be accumulated by saving a particular amount period (day, week, or month) over a given amount of time, or by computing how much must be saved each period over time to achieve your savings goal.

Periodic amounts invested will be compounded into the future (or discounted to the present) at a periodic rate derived from the annual interest rate chosen.

Make small changes in the amounts or interest rates and see how much they influence the results. The magic of compound interest over the long haul really makes a difference.
