Family Accounting Tool

opensource

The personal accounting tool that me and my wife are using on a weekly basis since 2011. Its main feature is the distinction between money reservoirs (like a wallet) and accounts (like 'Jens' or the 'common account').

It is a PWA compliant web-app that works offline and syncs offline edits with the server when connectivity returns. It does so by storing all data in an in-browser database (Loki JS) and performing all queries locally.
