TabSplit allows users to keep track of their "social debts". So if you go out and share a tab it’s easy to split it up between your friends and know who has paid the tab and who owes you the remaining money. Current features include:

Tabs (Split up itemized bills between friends - e.g. restaurant bills - in this android app you can take a picture of a bill, split up the items and later digitalize the items on the website tabsplit.net) Payments (Record loans to your friends) Joint Payments (Group investements, e.g. if you share the hotel bill)
