go on, break it

This is the real app, on somebody's sample ledger.

Nothing here is saved, and this page cannot save. It runs on an in-memory copy of the database, so closing the tab takes your changes with it. Press N to add a transaction, pick the euro account and watch what happens to the currency. Starting a ledger of your own, importing a CSV and exporting your data are what the paid app adds — we would rather say so now than after you have typed in a month of expenses.
