IOU | UOI - I Owe U Owe I

Do you remember who borrowed your boxed DVD set of "Godfather"? Or, who took your copy of "Da Vinci Code" that you had to stand in line for an hour to be autographed by Dan Brown? How about the missing shovel - was that next door Joe or Mike who lives across the street?

IOUOI is unlike any other application on the App Store - its lets you easily track all your borrowing and lending activities.

Great update

App Ratus

Thanks for the update with the bug fixes

Pretty cool


I tested every free IOU app there is. Like 7 of them. I ended up keeping this one. It was a tough choice between this one and "Owed" because owed allowed two things this app doesn't have:
1. An app badge telling you how many things are still loaned out
2. A due date setting
I chose this one because I figured the developer can easily add those faster than owed can add the things it's missing.
Hopefully those two features will come soon. I'm willing to pay for them as well.

Just what I need!


I've been looking for this kind of app for a while. Did research and was even willing to pay for an app as long as it had what I needed but didn't have to cause this is free. It has a way to make/receive partial payments on a loan which is awesome cause I really needed that.
