Convert between 32 of the world's major currencies using live, mid-market exchange rates. Built for travelers, expats, and anyone who needs a quick answer without the clutter.
LIVE RATES, TWO INDEPENDENT SOURCES
Rates are pulled from two providers: the European Central Bank (via Frankfurter) and ExchangeRate-API. If one source fails, the app automatically falls back to the other — and always shows you which source is currently live. Stale numbers are never presented as fresh.
Historical trends are drawn from European Central Bank data where available. For the small number of currency pairs the ECB does not publish, the chart falls back to an estimated trend and labels it "Sample" on screen, so you always know which is which.
WORKS OFFLINE
No signal? The app caches the last successful rate table and keeps converting with it, clearly labeled "Offline · Data as of [time]". You always know whether you are looking at live data or cached data, and how old it is.

PRECISION YOU CAN VERIFY
Conversions run in decimal arithmetic rather than floating point, so results round the way you would expect. Intermediate precision is kept to 5 decimal places by default and can be raised to 8. Currencies that have no minor unit — the Japanese yen, Korean won, Indonesian rupiah, and Vietnamese dong — are handled with 0 decimals automatically.
PRIVACY
The app collects nothing. No accounts, no sign-in, no analytics, no tracking, no ads. Your favorites, currency pair, and preferences are stored only on your device and never leave it.
IMPORTANT
Rates shown are indicative mid-market reference rates provided for information only. They are not investment advice, and they may differ from the rate your bank or card issuer actually applies, which typically includes a margin.
