A detailed look at what FX Europe can do

🏛️

Official ECB Exchange Rates

FX Europe uses exchange rate data published by the European Central Bank. The ECB publishes reference rates for around 30 currencies against the Euro every working day at approximately 4:00 p.m. CET.

These are reference rates — the same data used by banks, businesses, and governments across Europe. No proprietary rates, no hidden markup, no "our rate vs. the market rate" confusion.

Important: ECB reference rates are for informational purposes. They're not transaction rates — your bank or exchange service will have its own spread. But they're the best neutral benchmark available.

🔢

Currency Converter & Calculator

The main screen shows all ECB-supported currencies with rates per 1 EUR. Tap any currency pair to open the calculator for a specific conversion.

  • Bidirectional conversion — enter an amount in either currency and get the result instantly
  • One-tap currency swap — switch base and target currencies without navigating away
  • Locale-aware formatting — decimal separators, grouping, and number formats match your region
  • Flag-based currency selection — tap the flag icon to pick any supported currency

Non-EUR pairs (like USD/GBP or PLN/CZK) are calculated via the EUR cross rate. This is standard practice and clearly noted in the app.

📴

Offline Support

Exchange rates are cached on your device automatically. When you're offline — no Wi-Fi, no mobile data, airplane mode — the app falls back to the last successfully fetched rates.

This makes FX Europe genuinely useful while traveling. Underground in the Prague metro, on a flight across Europe, or in a building with no signal — you still have a working currency converter.

The app shows when rates were last updated, so you always know how fresh the data is.

📱

Home Screen Widgets

Add currency pair widgets to your home screen for at-a-glance rates. See EUR→PLN, GBP→CZK, or any other pair without opening the app.

  • Available on both iOS (WidgetKit) and Android
  • Tap a widget to jump directly to the calculator with that pair pre-loaded
  • Rates update automatically when new ECB data is available
  • Country detection suggests relevant default pairs based on your location

Premium feature: Widgets are available to premium users. Free users can try the app and upgrade for a one-time payment to unlock widgets and remove ads.
