## What is Launchly?

Every run. Every launch. Down to the tenth.

Launchly measures your acceleration time — 0-50, 0-100, 0-150 and 0-200 km/h — with precision that goes far beyond a basic GPS stopwatch. Pick your car, floor it, and see exactly what it did.

WHY LAUNCHLY IS DIFFERENT
Most phones only deliver GPS updates at 1 Hz. Launchly fuses GPS Doppler speed with 100 Hz IMU data (accelerometer + gyroscope) to fill the gaps between fixes. The result: sprint times accurate to the   
hundredth of a second, even on devices with slow GPS.

FEATURES
  • Measure 0-50, 0-100, 0-150 and 0-200 km/h
  • Split times captured automatically within a single run
  • Live speed gauge in multiple styles (PRO)
  • G-force chart for every run (PRO)
  • Garage: manage multiple cars with photo and license plate
  • Compare with friends on a leaderboard
  • Export your GPS log for your own analysis

PRIVACY FIRST
Measuring 0-100 km/h is completely free, no account required. Your runs are stored on your device — they are only uploaded if you sign in to share times with friends.

For anyone who wants to really know what their car can do — on the road or the track.

Imperial units: switch to mph and run 0-60 mph as its own finish line.

A rebuilt friends leaderboard with a podium, grouped per person and per car.
