To those who haven't done so yet, it's always a good idea to make it easy for people to translate your applications. You can apply for hosting your applications' translation efforts for free at Weblate or Transifex as long as you show them the source code is available (which doesn't seem to be a problem looking at this thread!). This lets anyone translate your applications online, without requiring them to know how to work with GitHub or the likes.

The more languages your applications are available in, the more useful they will be!
