I want to convert money values from a currency to another, for instance EUR to USD.

Requirements:

  • Run on Android
  • Open source (imperative)
  • Usable offline (exchange rates get updated from time to time, not too strict on that)

Bonus for a easy input of numbers without having to firing up the default software keyboard (which contains all letters whereas I only need numeral and decimal point).

    Note you can enter 50 EUR to USD in browser and you'll get the answer from Google, works in Android too. Of course it's neither open source nor usable offline.

  • I'm curious, could you explain why being open source is important? I would think that a quick comparison against another app/website would quickly show that it worked and I can't think of any security/privacy concerns unless it is asking for too many permissions. Commented May 18, 2014 at 13:58

    @MatthewRead: I don't trust code I did not compile myself. A currency converter will need to update its data from time to time, which means Internet permission, which means the app can report on me (and probably will, as most non-open source apps include statistics gathering clients like libGoogleAnalyticsServices.jar)

Android Currency Converter seems to be what I was looking for:

Android Currency Converter

A few drawbacks:

  • Not that many currencies
  • Maybe a better UI could be designed, even though I have no specific improvement ideas
