Payla

Payla keeps track of what a group spends together and works out who owes whom. You can create a group for a flat, a trip, a couple or a club, invite people with a QR code or a link, and log expenses as they happen. Bills can be split equally, by percentage, by shares or by exact amounts, and a receipt photo can be attached to any entry. Friends who haven't installed the app yet can be added as virtual members.

Every change syncs to the whole group in real time, and expenses can be entered in any major currency. When it's time to settle up, Payla calculates the smallest number of transfers needed to clear every balance. Saved IBANs turn each bank transfer into a copy-and-paste job. Payla Pro adds personal monthly budgets, group spending charts and exportable reports.
