The Video Loop will be your car's black box. In the event of a crash or incident you will have captured it on your phone. The Video Loop app continually records video in a loop without filling up the phones memory, and once stopped you are able to view the last 15, 30 or 45 seconds. NOTE: Galaxy S not supported.
