You and your friends or co-workers just finished sharing a nice dinner and now it’s time to pay the check. One person gets out a pen and starts divvying the bill by hand on a napkin.

Convenient and helpful

No need to dread the end of the meal and how to split the ticket. This app does it all for you.
With this app you can split the bill evenly among friends, or adjust it for situations where everyone wants to pay their exact share. There's an IOU list conveniently linked to your contacts and a new name can be added from the IOU screen. It might be nice to have a "favorites" or "recents" screen here. Also, the "resolve" feature is convenient, with the ability to send a reminder email to the contacts. Really like the international currency options which of course makes this app great when travelling abroad. This app is a great organizer and a handy tool to keep track of everyday expenses. A stress reliever.


From the developer

Please send suggestions, questions or enhancement requests via e-mail, so I can respond to them and so I am sure to see them. (Support e-mail address is on the Help screen). Thanks!

To the person who suggested partial IOU payments, I've added that to the list of things to consider for future updates. Note that you can simulate this functionality now, in the meantime: If you've entered a loan of $100 to someone, to take a partial payment of $25, add a new transaction, hit "Borrow", enter $25, and add a note like "partial payment". Now it will show them owing you $75. You can email the entire thread as a receipt. I know it's not exactly what you're looking for, but it should hold you over for now.

Easy and Convenient

I usually hate it when people put me in charge of divvying the bill when we eat out (don’t even get me started on taxes and tips), but thanks to this app, I don’t mind doing it anymore. Who Owes What makes it really easy to determine how much each person should pay. Oh, and my officemates love this app, too! We go out to happy hour every week, and we take turns footing the bill. Who Owes What keeps track of whose turn is it to pay, which is a very convenient feature. Highly recommended!
