This is one of the best apps for expense sharing! Functionally very good, but the UI is a little difficult - but not to complain has all the features I needed. I just added the people in trips to my contact list (with email) After the trip export the expenses to them very easily. Great Job! Pros: Functionally Solid Email Expenses Free! Cons UI - Takes a little while to get used to Only Contacts can be added as Friend
