Split shared costs cleanly across a trip, a household, a dinner — and settle up in the fewest transfers possible.



Anyone in the activity can add an expense. Balances update the moment they hit save.
The math finds the shortest set of transfers that clears every debt.
No matter which currency you use in the trip, you can always convert to your home currency.
Pick a name for your trip, set base currency and pick a theme — forest for hikes, sea for beach houses, city for weekends away.
Invite them by email if they use BalanceSplit, or add them as nicknames if they don't. Both work; balances still calculate.
Each expense is one row: who paid, how much, what for. Split it evenly, or pick specific participants when it's not an all-hands cost.
BalanceSplit computes the minimum set of transfers and shows who pays whom. Share a copy of the split with your team mates.
The activity card takes the palette of what you're actually doing. It's cosmetic, but it makes a long list of trips instantly scannable.
The paid tiers raise the ceiling on how much you can track — the settlement algorithm and every feature work identically on Free.
Prices shown in USD; your local price is set by Apple and Google and appears in the app when you upgrade. Invited participants never pay — they only pay if they later create their own activities beyond the Free limits.
