The app lets you see what your camera sees, giving you a live preview for positioning the camera and framing your shots. You can playback your videos, view your photos, browse and delete files on the Micro SD card, and even share them via email, text, and social media sites. The app also gives you instant access to the GoPro Channel to see other videos shot by GoPro cameras, and can even update your camera's software.
