GapMeter: Following Distance

Everyone knows the two-second rule. Almost nobody can actually measure it. GapMeter uses your iPhone's rear camera to show, in seconds, how far you are behind the vehicle ahead, and tells you with a sound when that gap is closing fast. Mount your phone, tap Start, and drive. You don't need to look at the screen. HOW IT WORKS • Mount your iPhone on the dashboard or an air vent, rear camera facing the road. • A one-minute guided setup levels the mount and learns your vehicle. • Tap START. GapMeter finds the vehicle in your lane and shows your following time in seconds, with the distance and your speed. • When you are closing in quickly, an alert tone plays over your music or your car's speakers without interrupting navigation. • When you stop, you get a clear summary of the drive.
