A weekend away can leave one person paying for the groceries, another covering the taxi and everyone trying to remember who owes whom. A group chat can preserve the receipts, but it does not do much to reconcile them. Potjar is an Android app for keeping that shared tally and working out a way to settle it.
The basic idea is a ledger for a trip, flat or dinner. You create a group, add its participants, then record expenses and who paid. The app calculates each person's balance and suggests payments intended to settle the group with fewer transfers. That last step matters: a list of individual debts can be harder to act on than a short set of payments between people.
From a receipt to a balance
Potjar offers several ways to divide an expense. An item can be split equally, assigned as exact amounts, divided into shares, or allocated by percentage. Those options cover common cases, from splitting a restaurant bill evenly to accounting for a household cost that not everyone shares in the same proportion.
The resulting balances are not the same thing as money moving. Potjar can record a settlement, and its suggested payments help people see what to pay, but the app does not process payments itself. It can include optional UPI or PayPal.me links that open a person's own payment app. The group still has to make and confirm the transfer outside Potjar, then keep the ledger current.
That separation makes the app a record-keeping tool rather than a wallet. If plans change, expenses can be edited or deleted, and settlements can be recorded. For people who prefer to keep a copy elsewhere, the description says groups can be exported to CSV, while JSON files are available for backup and restore. Summaries can also be shared as text or as an image card.
Offline by design, with a trade-off
Potjar is described as requiring no account, showing no ads and having no internet permission. The developer says it does not use analytics and that group data stays on the phone unless someone exports or shares it. That makes the product's privacy model simple to understand: the app is intended to work locally, and sharing or backup is a deliberate step rather than automatic syncing.
The same choice creates a practical constraint. There is no described shared, live group ledger that updates across everyone's phones. Someone needs to maintain the group record and pass around a summary, image or exported file when others need the information. That may suit one person managing a trip's expenses, but it is less convenient if every participant expects to enter costs into a single synchronized account.
There are also boundaries to the calculations. Each group uses one currency, with no exchange-rate conversion. A trip through multiple countries would therefore need a separate way to convert costs before recording them, or separate groups for different currencies. The developer describes the fewest-payment suggestions as supporting groups of up to 12 people, so larger groups should not assume the same settlement assistance.
Who should consider it
Potjar is free and runs on Android. It is currently in Google Play closed testing, so availability is a meaningful caveat for anyone hoping to install it immediately. The product's stated accessibility options include large text, light and dark modes, and right-to-left support, but its platform list is Android only.
For a small group that wants to split expenses without creating accounts or relying on an online service, Potjar is a straightforward concept: enter costs, choose how they are divided, review balances, and handle payment separately. It is a poor fit for groups that need automatic syncing, multi-currency accounting, or payments completed inside the app. Its usefulness depends less on elaborate finance features than on whether everyone is willing to keep one local record up to date.
