Finance Tracker
2026 Logging an expense in three seconds Prototype
A personal finance app for Android and iOS. Logging what you spend should take about three seconds: open the app, type the amount, tap a category.
Why I made it
Most budgeting apps want you to categorise a long list of bank transactions after the fact, and I never kept up with that. This one is built around entering things as they happen, with no account and no network needed. I ended up not using it day to day, so it stopped at a working prototype.
A few decisions
- Money is stored as whole øre (integers), never as floats.
- Rent and salary post themselves and are kept out of the day-to-day spending figure, so one big payment doesn't make the daily average useless.
- Entries are append-only with a UUID and soft delete, so syncing between devices would be simple later.
