People seem to complain about the app a lot too...the biggest gripe being that you can't preview the camera view (like with the GoPro app) to make sure the camera is properly aimed. Instead you have to record some, watch the vid on a computer, adjust, repeat. etc. I remember doing this on the older gopro and it was always a pain. I wonder how easily it rotates...can it accidentally be bumped, changing the angle or does it lock in?
