About 366.money
366.money is a web application for tracking personal expenses, income and transfers when your money lives in more than one currency and more than one country. The core features are free.
What it does
You keep every asset in one place — bank accounts, cash, and crypto wallets — and record what you spend, earn and move between them. Every balance is converted with live exchange rates, so your whole financial picture adds up to a single number in whichever currency you choose.
- 50+ fiat currencies and 80+ cryptocurrencies, mixed freely across assets.
- Unlimited assets — a bank card in one country, cash in another, stablecoins on an exchange.
- Transfers between currencies. Lock the rate, the amount sent or the amount received, and the remaining field is calculated for you.
- Analytics by category, with filters by asset, category and date range, and running totals.
- Mobile-first interface that can be installed on a phone home screen as a web app.
Who it is for
It was built for the situation where the usual expense trackers stop being useful: salary paid in one currency, rent due in another, groceries in a third, and part of your savings in crypto. If you have ever kept a spreadsheet with a column per currency, this replaces it.
How it works
- Create an account with an email address and a password.
- Add your assets — each with its own currency and starting balance.
- Record expenses, income and transfers. Balances and analytics update as you go.
What it costs
Everything described above is free, with no trial period, no limit on assets and no advertising.
A paid subscription is planned for features that rely on AI: entering operations by voice, and reading them from screenshots, bank statements and receipts. These features are not available yet.
