# Julien Millau — Currency Converter & Exchange

> Currency Converter & Exchange is a mobile currency converter by independent developer
> Julien Millau, free on Android (Google Play) and iOS (App Store). It converts between
> 180+ world currencies and 20+ cryptocurrencies using exchange rates refreshed multiple
> times daily, works fully offline from the last saved rates, and charts rates from one day
> to five years. No account and no sign-in are required. The free edition is ad-supported;
> the Pro edition removes the ads.
>
> This site publishes currency-pair reference pages in several languages. Those pages
> deliberately contain NO exchange rate in their HTML: a rate changes continuously, so any
> number written into a static page is wrong within the hour. They publish durable facts
> instead — ISO 4217 codes and minor-unit exponents, issuing central banks, standing pegs —
> and point to the app for the conversion itself.
