FEATURES IN DETAIL
----------------
[ Entry ]
Tap a large category, enter the amount on a calculator keypad, pick a wallet, date and note. The quick-entry box takes several items in one sentence and guesses the category. Undo a delete with one tap.

[ Receipt scanning ]
Photograph a receipt or pick one from your library. The app reads the total and date on your device and fills them in for you to check.

[ Calendar ]
Daily totals on every day. Tap a day for details, swipe to delete, search by note, category or wallet.

[ Reports ]
Income, expenses and net cash flow by month or year, a category pie chart and tips on where to cut back. Plus yearly, per-category and all-time reports and a 12-month balance trend.

[ Budgets ]
Set a limit per category and an alert threshold (for example 80%). The app warns you before you go over and never blocks you from logging.

[ Wallets, goals, recurring entries ]
Cash, bank accounts, e-wallets and credit cards, each with its own balance; transfers are not counted as income or expense. Create saving goals and contribute over time. Rent, salary and subscriptions are set up once and logged on the right day, or the app asks you to confirm.

[ Shared family book ]
Create a shared book (Pro) and invite family with a code or QR (up to 5 members). Everyone logs and sees the same book; shared expenses are split evenly and the app shows who has paid what. Invited members do not need Pro.

[ Privacy & security ]
Your data lives on your device. Lock the app with Face ID, Touch ID or a passcode. Sign-in is optional; when sync is on, data travels over an encrypted connection.

[ Backup & export ]
Back up to a file and restore when you change phones. CSV export is free; Pro exports Excel with monthly and category summaries, plus PDF reports.
