GoPro has launched a free companion app for their rugged mountable HD cameras. The Android app provides access to the whole suite of settings, and offers a live preview of what the camera sees, which should help with framing when you're about to leap out of an airplane, wingsuit to the slopes, land on a snowboard, pop a backflip off the first jump, and chug a Mountain Dew mid-air.
Before getting all extreme, be sure your phone is running Android 4.0 and up and that your GoPro camera is loaded with the most recent software. Also, the Hero 3 cameras aren't compatible just yet. though updates are on the way. For the time being, only Hero 2 cameras with Wi-Fi BacPac accessories work.
Any GoPro owners out there? What do you use the camera for? Will a mobile app really help things along?
