A few useful answers
Currency Converter FAQ
Where can I see available currencies?
Search the available currencies in Callie. Availability depends on the exchange-rate data; a currency list is not a guarantee that every rate pair is available.
Are the rates real-time?
Callie uses public Frankfurter exchange-rate data. It is not a live trading or real-time market app.
Can I use cached rates offline?
After one successful update, Callie can continue converting with the last successful cached rate snapshot.
Is this for crypto?
No. Callie is focused on public currency exchange-rate data, not crypto conversion.
