AA keeps track of who owes whom in a group, and leaves it that way. Nobody settles up at the end: whoever owes the most takes the next bill, so there is always a reason to meet again. Record what you paid and who was there. AA works out each person's share and updates what everyone owes. Multi-currency Track costs in more than twenty currencies and read the total in any one of them. Works offline Add expenses with no signal — they upload themselves once you are back.
