Beastgrip Pro: Turn Your Phone Into Mobile Video Rig
Compatible with iOS, Android and Windows phones
This is a rig system for your phone that lets you take better video by adding stability, mics, lights, and lenses.
Kyle Russell of TechCrunch says "Nearly every aspect is modular or expandable. Depending on what you need to shoot, you might put your phone on a tripod for smoother shots, add a directional mic for better audio during interviews, or swap out lenses to capture wide-angle footage or to get better distance shots without hurting quality as with digital zoom."
