How fast does your car really hit 0–100? Tap Start, hit the gas, and let GPS time it for you. 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. BIG, EASY-TO-READ SPEED Extra-large digits show your current speed so you can read it in a glance. KM/H OR MPH Switch between kilometers and miles to suit your preference. SPEED CURVE CHART See your whole run as a curve and check how each stage of the acceleration performed. HISTORY & ICLOUD SYNC Your latest 10 results are saved automatically, so you can compare before and after mods or across different road conditions.
