Features

Trip planning meets clean settle-up.

One app for the planning chat and the post-trip reckoning — without forgetting which currency was which.

Itinerary + budget side by side

Each leg of the trip — flights, lodging, activities — carries its own budget and shared costs.

Multi-currency, sane FX

Auto-fetched rates with manual override. Every line item shows both the local price and the trip currency.

Weighted shares

One person skipped the rental car. Another shared the suite. Custom shares per expense — without spreadsheets.

Live balances

See who’s up, who’s down, and what a fair next-round looks like, in real time across the group.

One-tap settle on arrival home

We compute the minimum number of transfers, so a group of five doesn’t finish with twenty Venmo notifications.

Offline-first

Works on a mountain, in a metro, on the wrong side of an international roaming charge. Syncs when you’re back online.
