Great concept. Couldn't wait for app like this after losing scanner and a company at tracks where bought another went out of bus. Wanted it for watching on TV and listening to scanners too though. Agree Needs ability to delay the scanner since iS always a lap or several ahead of TV depending on track. Also the All Scan feature should have a visual update of the number of the car whose channel is being broadcast. Those 2 features would make it indispensable. Probably won't keep it without them.
