Track your cash, simply.

A lightweight cash book for Android. Organize transactions into books, categorize and search them, back up your data whenever you want — all without an account, and without your data ever leaving your device.

Features

Books

Organize transactions into as many named books as you need, each with its own running balance and totals.

Cash in / cash out

Every transaction is amount, type, date/time, an optional note and category, and an optional photo attachment.

Filter & search

Filter by type, category, or date range, and search notes live as you type.

Categories

Starts with a predefined set of categories and lets you add your own.

Backup & restore

Export all your books, transactions, and categories to a single .xlsx file whenever you like, and restore from it on any device.

Light & dark themes

Follows your system's light/dark setting automatically, with a manual override in Settings.

Fully offline, by design

Cash Flow needs no internet connection to work. There's no account, no cloud sync, and no analytics, telemetry, or crash reporting of any kind — your data stays on your device unless you choose to back it up yourself.
