As its name suggests, Socialcam is very social. You can follow other users or tag those who appear in your videos. Like other apps I tested, you can also respond to videos, "like" them, or share them with others. If you want, Socialcam will automatically push all these actions to Facebook and tweet about the ones you like on Twitter. And the app has more ways to share your videos than any other I tried. So many choices can make the app's interface feel too crowded, though.
