Hi, I am the developer of this app. It is handy tool to evaluate financial terms when lending or borrowing money. It free, lightweight, fully native. Pure math. Interest 4 - App info is currently processing and/or the app is not yet fully available for sale on the US App Store.
Very simple app but is very useful. Getting a loan and paying its monthly bill will be easier. This will surely help a lot of people.
