DivvyIt keeps track of shared expenses when youre out with friends and tells you the quickest way to settle up.
Simply enter in expenditures as they happen and when youre ready to settle up itll calculate who still owes what and to whom.
Instead of simply averaging out costs over a whole group of friends, DivvyIt records who actually participated in a particular expense as well as who paid for it. This makes sure that when youre ready to settle up, each person is only responsible for the expenses that they were actually a part of.
