Due to API change, most 3rd party app die. Some app like Atom still work, but I doubt it will stay any longer. I do try some open source app for desktop, it work fine with my API key (rtv, troddit). I am going to get source code of an open source code, and self build my app with my API key. I would like you recommend me some open source Android app that easy to build. I am not mobile developer, but I have some developer skill, a Ubuntu user.
