I love this app. You have to put a file on the sd card for hero 2 and 3 but its simple. Copy and then paste it. I use the hero 3 black to remotely take pictures and video and now I can view them without opening the case and download them right into the photos. Only thing that stinks is that its a little slow but much better than opening the case and hooking it all up.
