TripKitty: split travel costs without an account.
view on the app store ↗ ios · iphone & ipad
Log it. Split it. Done. TripKitty is built for group trips — no account, no subscription, no adverts, and everything stays on your device. At the end, one clear answer: who pays whom, with as few transfers as possible.
An expense in about three taps
Type an amount and save — that's usually the whole entry, thanks to smart defaults: the payer defaults to whoever paid last, and everyone active on the trip is a participant unless you say otherwise. Category chips (food, shopping, drinks, accommodation, fuel, other) and a refund toggle for deposits or cancellations keep the log tidy without extra typing.
Fair, even when it's not a straight split
A person can be given a "factor" — a child counting as half a share, say — and a long press overrides a single expense, for the guest who only joined for two of three nights. Private items on a shared receipt, like one person's own round of drinks, can be split out so only they pay for it.
Settling up, precisely
TripKitty's settlement algorithm guarantees at most n−1 transfers for a group of n people, worked out deterministically with exact integer-cent maths and largest-remainder rounding, so the totals always add up exactly. A settlement card shows who pays whom, with a done-checkbox — and an undo — for each transfer.
- Record payments between people so the final settlement stays accurate
- WhatsApp text export and a full PDF export of the settlement — both free
- Automatic backup to your own iCloud Drive, plus manual file export and import
- One currency per trip — euro by default, Swiss francs selectable
- First trip entirely free, including unlimited people, expenses, PDF export and backup
TripKitty keeps score of who owes whom — it does not process payments itself and is not a financial services provider; settling up still happens through your own bank transfer or payment app. Digitalbucht is the sole proprietorship of Emil Deak, based in Wülfrath, Germany.
Data and privacy
The app uses the camera and photo library for receipt photos. There is no server of its own: trips are automatically backed up to your personal iCloud Drive folder if iCloud Drive is switched on, and the provider has no access to that folder. A trip can be shared as a file, for example over WhatsApp; importing someone else's trip file brings its names and expenses onto your device too, but nothing is sent back to the provider. No adverts, no tracking.
