Currency Rate Calculator

About this app

Convert any currency in seconds — free, offline, no sign-up. Whether you're boarding a flight, shopping from an overseas store, or just curious what your salary looks like in euros, Currency Converter gives you instant, accurate results without the clutter. Live rates, always up to date Exchange rates refresh daily from two independent sources — the European Central Bank via Frankfurter and ExchangeRate-API — so you always see reliable, current figures. Every rate is time-stamped so you know exactly how fresh your data is. Works everywhere, even without signal No Wi-Fi on the plane? Roaming switched off? No problem. Your last-fetched rates are cached on-device automatically, and a built-in snapshot of rates ships inside the app itself — so Currency Converter always shows real numbers, never a blank screen. 150+ world currencies From US dollars and euros to Thai baht, Nigerian naira, and Chilean pesos — all major and most minor currencies are covered. If it has an ISO code, it's in the list. My Rates — track one amount across many currencies at once Set a base amount (say, 500 USD) and see it converted into every currency you care about on a single screen. Swipe to delete ones you don't need, tap any row to update the amount. Ideal for comparing prices across countries or budgeting a trip. Save conversions for quick reference Bookmark your most-used pairs so they're one tap away every time you open the app. Clean, fast, lightweight The app launches in under a second and doesn't ask you to create an account, subscribe to anything, or hand over personal information. There are ads to keep it free — that's the only trade-off. Free. No account. No sign-up. No subscription. Just open it and convert. Currency Converter by Ack — simple tools, seriously useful.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
