Beanbook keeps your books where they already live: in ordinary Beancount text files, on your phone. It runs the real Beancount and Fava on the device, so the figures you see are the ones bean-check and Fava produce on a desktop. There is no account to create, no sign-in and no server run by this project. Your ledger is a folder of text files you own. <b>What you can do</b> • Read your ledger: a Home page with net worth and where the money went, a searchable Journal, and Balances for every account. • Show figures three ways, as Fava does: Units, At cost, or Market value. • Add entries and other Beancount directives with a form that shows the exact text before it is written. • Edit the files themselves, with every save re-read by Beancount before it is called saved, and an Undo for the last change. • Scan receipts and statements into PDFs and file them under an account. • Open Fava's Reports inside the app. • Mirror a project to a folder you choose, and back it up with an optional passphrase. • Use Beancount plugins and Fava extensions, and run your own Python scripts. • Home-screen widgets for balances and net worth. <b>Your data stays yours</b> • No telemetry, analytics, crash uploads or ads. • Local mode makes no network requests. • If you turn on Share on Wi-Fi, other devices can reach your Reports only while it is on, only on a private network, and only after signing in. • Nothing is sold, and there is nothing to subscribe to. <b>Two editions</b> The Expert edition adds plugins and packages that include native code, fetched only when you ask. The Play edition does without them. Both are free. Beanbook is an independent project. It is built on Beancount and Fava and is not affiliated with or endorsed by them. It comes with no warranty, as its GPL-2.0 licence states: keep backups of your ledger.
