Step 1
Start a list
One for a trip, a house or a night out, in its own currency.
Step 2
Add what was paid
Split it equally, by exact amounts, or item by item from the receipt.
Step 3
See who owes whom
The balances settle in as few payments as possible.
Step 4
Settle up
Add how you'd like to be paid back, and mark each payment as done.
