Great price! Thanks!

I own a note secured by real estate. Can anyone recommend an app that will help me to keep track of payments and interest. The payments will be irregular at varying intervals with a final balloon payment in a specified number of years. A local credit union will do it but require a small fee that I can avoid.

Thanks to everyone who submitted suggestions. We have some great possibilities!

In for 1. Smoked garlic just has to be good! Thanks!
