Ring has some UI problems but I hope it'll get better. It's open source and a company in Montreal contributes a lot to its development.

The big problem right now is the scope of the app. They want to do too much at the same time (text, voice and video).

Anyway, I like the effort and I hope it succeeds.

It's exactly the same scope as the most successful person-to-person communications app yet, Skype.
