Oh mygastos!

The group tab for trips, rent, and every dinner where someone said “I’ll get this, just pay me back.” Log who paid. OMG! tells everyone who owes who.

Example tab: a Boracay trip for four friends, and who pays whom at the end.

Three steps. Zero spreadsheets.

  1. Start a group.

    Name it after the trip, the house, or the group chat. Everyone joins from one invite link.

  2. Log who paid.

    Amount, who paid, who shared it. Done before the bill folder comes back.

  3. Settle up.

    OMG! works out who pays whom, in the fewest transfers. Nobody opens a calculator.

12 IOUs in. 3 payments out.

On the Boracay trip, all four paid for something, so on paper everyone owes everyone. OMG! nets it all out: Ana gets paid back, everyone else sends one transfer, done.

ABCD
Before: everyone owes everyone
ABCD
After: three transfers to Ana
