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.

Please do not post negative reviews. Contact me instead using http://www.proximux.com/iouoi/support. This application takes a lot more effort than iFart, Fart for Free and such gimmicky applications. A little encouragement would go a long way.

Thanks for track payments feature

Thanks for finally adding the track payments feature. Will contact you with some suggestions but overall great addition.

3/5 stars

ability to email entire balance due for a contact

if i lend a guy $100 and later he pays me back $50 and then perhaps i lend him $20 again , i should be able to email him the entire list of transactions and a balance due, not just 1 transaction at a time. currently if i have 5 transactions with a person, all need to be emailed separately and then he has to figure out in the end how much to pay me or what I owe him.
Application should provide feature to email a 'contact' saying something like :

U owe me -
$100 Rafting-vacation 5/2/2010
$20 Starbucks 9/2/2010
$120 Total
I owe you -
$50 Payback 5/3/2010
$50 Total

Balance Due - $70 - U owe me

People...makes sense?

4/5 stars

Quality App

Basic, straightforward app that is adjustable enough to be useful. It looks like a winner. I would like to see autoback up feature to a cloud and/or task-calendar app auto syncs.
