The Afterparty Calculator is your go-to utility to quickly and safely share expenses with friends and family to see “who owes who” after a wild night out or a weekend in. Built to be used on the fly, you can use TAC to organize group bills whether it’s roommates splitting bills, splitting your weekend getaway, or organizing your Sunday brunches between friends.

TAC offers many features such as fast loading, grouping people for any splitting situation, backing up expenses so you can access them from any iOS or iPadOS device by logging in, and storing many attachments such as receipts for each party.
