Currency Converter: Live Rates

The fast, clean currency converter that works even when your Wi-Fi doesn't. Convert any amount between 150+ world currencies in seconds — dollar to euro, pound to yen, rupee to dirham, and hundreds more. Rates are sourced daily from the European Central Bank (Frankfurter) and ExchangeRate-API so you always see accurate, up-to-date exchange rates. And because a bundled snapshot ships inside the app, the converter keeps working fully offline — no signal, no problem. FEATURES • LIVE EXCHANGE RATES — daily rates from the European Central Bank and ExchangeRate-API, two independent sources for reliability. • WORKS OFFLINE — last-fetched rates are cached automatically. A built-in fallback snapshot means the app always shows numbers, even on a plane or in a basement with no data. • 150+ WORLD CURRENCIES — all major fiat currencies covered: USD, EUR, GBP, JPY, CAD, AUD, CHF, CNY, INR, AED, MXN, BRL, and many more. • FAST CURRENCY CONVERSION — type an amount, pick your currencies, done. No menus to dig through, no clutter. • MY RATES — pin a base amount and see it converted into all your favourite currencies at once. Great for travellers comparing prices in multiple countries. • SAVE CONVERSIONS — bookmark the currency pairs you use most for one-tap access. • CLEAN, MODERN DESIGN — lightweight, zero bloat.
