Fring is extremely excited (as you can see in the video below) to announce their Android app into the Market. Fring is the first to offer video calling for Android (you can also make free calls and chat using many of your favorite social applications). The app is currently available for all Android devices running 1.5+. However, for the full effect you’ll need a phone with a front facing camera like the HTC Evo. Hopefully, a larger number of future Android phones will include the dual cameras.
This app is quite similar to KnockingLive, but with the extremely important feature of including audio capabilities.
