Splitterator app for iPhone and iPad
Splitterator is for groups of people who spend money toward a common goal. Perfect for roommates, holiday gift shopping, parties, trips with friends, and anything thing else you can think of!
Just pick who spent money, how much they each spent, and Splitterator will tell you how much each person owes the other people in the group in order to even out the bill. Its that simple! Once the amounts have been calculated, you can then even send IOUs, Payment Requests, and Notifications to the whole group using your email!
