Expense Manager is a fast, private expense tracker for Android, iOS and the web. Your ledger lives in on-device SQLite behind a PIN — there's no backend, no account, and nothing ever leaves your phone.
Built for the 5-second entry you make many times a day — then powerful enough to slice a year of spending by category, tag and date.
Every entry is stored in on-device SQLite. There's no backend to breach and no account to leak — the app works fully offline, forever.
A PIN gates the whole app, with optional fingerprint or Face unlock and a short grace period so quick app-switches don't nag you.
One tap on the FAB, a Debit/Credit toggle that recolors live, a numeric keypad and smart category defaults. Duplicate a recurring expense in two taps.
Thirteen preloaded categories plus your own, and free-form tags on every entry. Colour-coded chips keep the ledger scannable at a glance.
Combine a category, multiple tags (restrictive AND) and free-text search to answer questions like "how much coffee at work this month?"
Monthly totals, a by-category breakdown, spend-over-time bars and a custom total-by-tags query — so the numbers actually tell you something.
Export a full-fidelity JSON backup or a CSV of entries, and import legacy history back in. Your data is portable because it's yours.
Built with Expo & React Native — the same app runs on Android, iOS and the web, with a clean light and dark theme on all three.
Delete gives you an instant Undo, entries stay recoverable for 30 days, and dates never drift — an expense on the 4th is the 4th, in any timezone.
This isn't a privacy policy promise — it's how the app is built. There is simply no server for your spending to be sent to. Nothing to opt out of, because nothing is collected.
Designed mobile-first around one idea: recording an expense should feel effortless, and reading your ledger should feel instant.
Toggle recolors the amount live; only title, amount and category are required.
Monthly totals, category breakdowns and a custom total-by-tags query.
Category + multi-tag AND + search, combined — answered in real time.
