About this app

Quantory is a budget tracker, car maintenance log, utility meter tracker, and intermittent fasting timer — all in one private, fully offline app. Track your expenses, log fuel and service costs for every car, record gas, electricity and water meter readings, and time your fasts. No account, no cloud, no subscription: every entry stays on your device.

💰 BUDGET & EXPENSE TRACKER
──────────────────────────
Track income and expenses across customisable categories. Add free-form labels to transactions, filter by label, and navigate by day, week, month, or year. Pie charts break down spending by category; line charts show daily totals over time. A collapsible category list lets you drill down into individual transactions without leaving the screen.

──────────────────────────
🚗 CAR MAINTENANCE & FUEL LOG
──────────────────────────
Keep track of every car you own. Log fuel fill-ups, services, repairs, insurance, road tax, inspections, and tyre changes — and set reminders so renewals never sneak up on you. Quantory calculates your fuel consumption between fill-ups, and a per-car summary shows what each vehicle is costing you, broken down by category.

──────────────────────────
🔌 UTILITY METER READINGS
──────────────────────────
Log meter readings for gas, electricity, and water. Quantory calculates your consumption between readings, tracks costs, and visualises your usage over time with bar and line charts. A yearly summary card keeps your totals front and centre.

──────────────────────────
⏱ INTERMITTENT FASTING TIMER
──────────────────────────
Start a fasting timer with a single tap. A circular progress arc shows your elapsed time against your target. The timer runs in the background via a persistent notification — it keeps counting even when the app is closed. Supports 16:8, 18:6, 20:4, OMAD, 5:2, and custom schedules. Session history tracks your streak, completion rate, and average fasting duration.

──────────────────────────
⚖ WEIGHT & BMI
──────────────────────────
Log weight entries and view your trend on a line chart. A BMI card computes your body mass index from your latest weight and your height (set in Settings), with a colour-coded classification badge.

──────────────────────────
📦 BACKUP & EXPORT
──────────────────────────
Export any module to CSV and share it with any app on your device. Take a full JSON backup of all your data and restore it at any time — useful when switching devices.

──────────────────────────
🔒 PRIVACY FIRST
──────────────────────────
Everything stays on your device. No account required. No data is sent anywhere. No analytics on your personal entries.

──────────────────────────
⭐ PRO UPGRADE
──────────────────────────
A one-time purchase unlocks data export, full backup & restore, and upcoming AI-powered insights. No subscription, no recurring charges — pay once, keep it forever.

What’s new

### Added
- Quantory may now invite you to rate it on Google Play after milestones like your 3rd completed fast or finished car task — at most once every 90 days, and never on errors
### Fixed
- The "update available" banner no longer appears during debug sessions (removed the debug fake-update simulation)
