ACCELERATION TIMING After you tap Start, timing begins automatically the moment you pull away and stops when you reach your target speed. See your result at a glance. Beyond 0–100, you can also measure 0–200 or 0–300. CUSTOM TARGET SPEED Choose a target speed of 100, 120, 150, 180, 200, 250, or 300. The default is 100. PRECISE GPS MEASUREMENT Speed is measured in real time with your phone's GPS. No extra hardware needed — just put your phone in a mount.
