XChange - Currency Converter

Convert between 100+ world currencies (plus crypto) instantly, with rates sourced from the European Central Bank and community-maintained open data. XChange works offline too: once you've loaded rates, conversions keep working using the last cached values, so you're never stuck without a number just because you lost signal. FEATURES • 100+ currencies, including major world currencies and major crypto • Works offline using cached exchange rates • Fast, clean, single-screen conversion, no clutter • Add and remove currencies to match what you actually use • No ads, no account required, nothing to sign in to PREMIUM (optional one-time unlock) • Multi-currency calculator: add and subtract amounts across different currencies • Unlimited currencies (free version supports up to 5) PRIVACY XChange doesn't collect, store, or transmit any personal data. There's no account, no tracking, and no analytics SDK. That also keeps it small: the whole app is under 5 MB. See our privacy policy for details. Exchange rate data is provided by frankfurter.dev (European Central Bank) and the open-source fawazahmed0/currency-api, both free and publicly accessible.
