Hostels, snacks, the museum that cost a small fortune. The One Bill keeps the trip about the trip — and the math out of the group chat at midnight.
No credit card required. Souvenir hoarding entirely optional.
You probably know the drill. We just made the math part vanish.

Give it a name like "Mountain trip" or "Group sushi night". Add the people who will be in on it.

Everyone in the bill can add expenses live. Updates show up instantly for the whole group, no refresh needed.

See who owes who, in plain numbers. Settle up before anyone gets weird about it.
I used to lose friends over twelve bucks. Now I lose them for completely unrelated reasons.
