StillOwe

Split something you paid for.

You get one link to paste in the group chat. StillOwe does the asking after that, so you never have to bring it up twice.

Beach house, three nights

This appears on every message, so people know who is asking

The whole amount, before splitting

One person per line. Add an email after a comma if you want StillOwe to remind them.

Everyone is split evenly. If the total does not divide, StillOwe says exactly who takes the extra cent.

StillOwe sends at most four reminders for a share — around day 3, 7, 14 and 30 — and they get further apart, never closer. Anyone can stop theirs in one tap, and saying an amount is wrong stops them immediately and for good.
