With Snapzy, you are able to use your Samsung Gear as a remote trigger and viewfinder. See what the camera on your phone sees, right from your wrist. For well-timed selfies, use the "delayed shot" feature to make sure you have time to get ready for the shot, once you have checked that the photo will be perfect.
Also, Snapzy is handy when you need to inspect something that can be hard to reach. Behind the washing machine, under the car? No problem - just enable the flash on your phone and see what the camera sees - right on your wrist!
