A few days ago I started developing a module for angular.js apps to translate the app content's. There are still a lot of things to do, to make this module uberspectacular, but you can already use it in your apps.
After publishing this module the first time, it turned out that there are already similar modules on the web (which I didn't know of). I took a look at them and each is following a different approach. Nevertheless, I kept developing my module since its following another approach and which currently fits to my needs.
It'd be great if some of you guys find this interesting and want to help out :) Pull requests are very welcome!
Cheers!
