About this converter
Free currency converter with live rates from exchangerate.host (ECB-based). Works offline with cached rates and a safe fallback.
Where do the exchange rates come from?
Rates are fetched from exchangerate.host (ECB-based). If the network isn’t available, the app falls back to your last cached rates so you can keep converting.
Does it work offline?
Yes. Cached rates are stored locally on your device and used automatically when live updates fail.
How often are rates updated?
The converter auto-refreshes about every 60 seconds. You can also click Update Rates anytime.
Are results accurate and do they include fees?
Conversions use mid-market rates from the provider with full internal precision; the displayed value is formatted for your locale. Bank spreads or transfer fees are not included.
Can I save or reuse currency pairs?
Yes. Use Save Pair to keep favorites; the app also tracks Recent Pairs.
Both are private and stored via localStorage.
