undeer is an offline-first money app for tracking spending, splitting trips, and running shared family budgets. No account required, and your data lives on your device first. Log money three ways Type it, say it, or snap it. Say "coffee, 45" and it's in. Point your camera at a receipt and Fundeer reads the merchant, the items, and the total. The things you log most stay one tap away on quick-add buttons and shortcuts. Split trips without the spreadsheet Start a trip, invite the people on it, and everyone logs as they go. At the end, one screen shows who owes whom, simplified down to the fewest payments. Equal splits, exact amounts, shares, or percentages, in as many currencies as your trip needs. Trip Mode Flip one switch when your trip starts and everything you spend โ€” typed, scanned, spoken, or imported from your bank โ€” attaches to that trip automatically. Each trip gets its own report: total spent, daily spending, and where the money went. Shared family budgets Share a budget with your family and track everyone's contributions and shared expenses in one place, with roles and permissions per member. Balances update live for everyone in the group. Bring your history with you Import a statement from your bank as OFX, QFX, QIF, or CSV, and map the columns yourself if the format is one we haven't seen. Existing backups from Money Manager, Monefy, Dime, and Quicken come across too. Catch up on what changed One Activity screen gathers what happened across your trips and shared budgets: new expenses, settlements, invitations, budget warnings, and role changes. Tap a notification and it opens the exact expense, budget, or settlement it was about. Analytics that earn their space Three views, one tab. Overview scores your month on savings rate, budget control, consistency, income flow, and balance. Breakdown shows every category and every day. Forecast projects how the month ends from your own habits. Rearrange the cards so your dashboard shows what you actually care about. FIRE planning Set your target number and retirement age, then watch your projected path to financial independence. Budgets and savings goals Set a monthly limit per category and see how much room is left. Create savings goals with deadlines and watch the progress add up. Offline-first, synced across devices Everything saves locally and is there instantly. When you're online, your changes sync across devices, and shared trips and family budgets stay in sync for everyone. Private by default Lock the app with Face ID, Touch ID, or your device passcode. The screen blurs the moment you switch away. Analytics and crash reporting are opt-in, and turning them off actually turns them off.
