Launchwell is the 0 to 60 GPS timer that tells you how far to trust its own result. Measure 0-60 mph or 0-100 km/h with your phone's GPS and motion sensor, offline, with no account and no ads. SAFETY FIRST Use Launchwell only on a closed-off course or private land where it is legal and safe. Mount the phone in a holder before you start, set everything up while standing still and never operate it while driving. Obey all traffic laws. You are responsible for how and where you drive. STARTS BY ITSELF • Auto start: put the phone in its holder, wait for the green light and just drive. The motion sensor notices the moment the car begins to roll, no tapping at the start line. • Standing start and rolling start: 60-100, 80-120 and 100-200 km/h, or 30-60, 50-70 and 60-130 mph. • Split times 0-50 and 0-100 km/h (0-30 and 0-60 mph) in the same run. • Quarter mile timer: 60 ft, 1/8 mile and 1/4 mile with trap speed. Optional 1 ft rollout like at the strip. • Braking distance 100-0 km/h (60-0 mph). • Voice readout: the app speaks your result, so you never have to look at the screen. AN HONEST GRADE FOR EVERY RUN A phone is not a professional timing box, and we say so. After each run Launchwell shows how good the data was: GPS update rate in Hz, satellites, speed accuracy and a grade A, B or C with the plus or minus in seconds. A slope check using altitude warns you when the road was not flat. Accuracy depends on your phone's GPS chip and the sky above you, and results can differ from the dyno or the drag strip. SHARE AND CHALLENGE • Timeslip card: every run as a picture in the style of a drag strip timeslip, ready to share. • Duel link: send a "beat my time" link to a friend. No server, no sign-up on either side. GARAGE AND TUNING LOG (PRO) • Several cars with best times, compared with the manufacturer's claimed figures. • Tuning log: note what you changed and see whether the times followed. • Speed-time chart and a side by side comparison of two runs. • Full run history, leaderboards for every distance and CSV export. FREE FOREVER • Unlimited 0-60 mph timer and 0-100 km/h from a standing start • Auto start, accuracy grade, voice readout and slope check • One car and your last 10 runs • Timeslip card (with Launchwell name) and duel link LAUNCHWELL PRO (7 DAYS FREE TRIAL) All additional times (rolling starts, 0-200 km/h, 60 ft, 1/8 mile, quarter mile timer, braking), chart and comparison, unlimited garage with tuning log, full history, leaderboards for every distance, CSV export and timeslip cards without the name.
