v1.0.0Jul 2, 2026
- Initial release — live demo and downloadable, runnable foundation.
Expense Tracker
Three-second logging, and a month view that tells the truth.
Description, amount, category — done.
Budget, spent, and remaining at a glance.
Bars that show where it actually went.
Overview
Expense Tracker is built around one habit: log it before you forget it happened. Capture takes three fields, the month view rolls everything into category bars against your budget, and the math is computed from your entries — never typed in. Swap the categories, currency, or budget logic to match how you actually spend.
