Everything You Need to Track Foreign Currency Savings

Built for people who hold money in multiple currencies and want clarity on what they've earned — and what they've lost.

Multi-Currency

Track EUR, GBP, USD, CHF and any currency pair supported by the European Central Bank. Add as many accounts and currencies as you need — there are no limits.

Interest Tracking

Per-deposit interest calculation with daily accrual. See exactly how much interest each deposit has earned, broken down by currency and account.

Smart Signals

Know when exchange rates are cheap compared to your weighted average cost. Make informed decisions about when to convert, backed by your own data.

Rate Alerts

Set target rates and get notified when they hit. Never miss a good conversion opportunity because you weren't watching the market.

Works Offline

Full functionality without internet. The app caches everything locally using service workers. Exchange rates sync automatically when you reconnect.

100% Private

Your financial data is stored in IndexedDB on your device. It never leaves your browser. We cannot see it, we do not collect it, and we will never sell it.

How It Works

Three Steps to Complete Currency Clarity

No signup, no onboarding wizard, no credit card. Open the app and start tracking in under a minute.

Add Your Accounts & Currencies

Create accounts for each currency you hold — a EUR savings account, a GBP current account, a USD brokerage. Name them however makes sense to you. Set interest rates if applicable.

Log Conversions With Dates & Rates

Record each currency conversion with the date, amount, and exchange rate you received. The tracker builds your cost basis automatically and calculates your weighted average rate.

See Real-Time P&L and Recommendations

Watch your portfolio value, unrealised profit and loss, and accrued interest update in real time. Smart signals tell you whether today's rate is above or below your average — helping you decide when to convert.
