Splitwise is the best way to share bills and IOUs and make sure that everyone gets paid back.
Use Splitwise to split household bills with roommates, to figure out costs for a group vacation, or just to remember when a friend spots you for lunch. On Android, iPhone, or the web (Split expenses with friends :: Splitwise), you can view your balances, track spending trends, set up email reminders for bills, and much much more!
