Core Features

Built so that tracking money never feels like a chore

No tedious categories. No clunky spreadsheets. Open it, log it, close it. Watch the trend grow over time.

Switch books on the fly

Renovation, Europe trip, daily household — every kind of spending gets its own ledger. Tap once in the top-left to swap, no overlap.

Project + records, two layers

Break renovation into "Elevator / Tiles / Appliances" projects. Multiple records hang under each. Budget / Paid / Left updates live — overspend is impossible to miss.

Search + sort

Fuzzy-search by project name or note. Sort by date or budget, ascending or descending. Find "how much did I last pay for tiles?" in two taps.

PWA · works offline

Add to Home Screen and it opens like a native app. Service Worker caches assets — works on the subway, in elevators, on flights.

Light & dark themes

Cream-white + amber by day; midnight-blue + sunset-gold at night. Auto-follows your system or flips with a tap. Eyes happy, math also happy.

Email sign-in · cloud sync

Once logged in, everything syncs to the cloud — switch device, pick up where you left off. SQLite-backed storage with local cache: safe and snappy.

Real Screens

For every project,
see how much is left

The header tells the whole story: Total budget / Total paid / Remaining. Every project card mirrors that structure. The red "Left" is your nudge to send the next payment.

Add a project with an "initial payment" baked in — no need to log it twice
Auto-stamps a ✓ Paid Off badge once the budget is hit
Sub-records: track multiple installments under each project — amount, date, note all kept
One toggle hides all sub-records — switch between summary and detail any time
First-screen ready on mobile, gracefully responsive on desktop
