Hi guys, I'm going on a five week trip with some friends - and it would be REALLY great to have an app to help us keep score of who owes who. I've found this app for the iPhone: The Essential Travel Utility - Road Trip Arbiter iPhone App by Talkndog Mobile but none of us have an iPhone - we're all Android and Nokia. Is there a similar app for the Android system? I already have an IOU app, but as you can imagine it only works on directs loans. help me have a care and I.O.U-note free summer.
