During the run
Know your time.
Every sprint.
A big, readable gauge you can take in at a glance, even with your phone in a dashboard mount. Launchly detects the launch itself through the accelerometer, so your timing does not have to be perfect.
- 0-50, 0-100, 0-150 and 0-200 km/h targets
- Automatic launch detection
- Split times at every threshold
- Dark and light mode
Why it is accurate
GPS + IMU.
Down to the tenth.
Most phones deliver GPS just once per second. That is five data points across a four second launch — nowhere near enough on its own. Launchly reads the accelerometer at 100 Hz and fuses both signals, then refits the whole curve against every GPS anchor once the run ends.
- GPS Doppler speed, not position deltas
- 100 Hz accelerometer, gyro-corrected for car pitch
- Kalman fusion during the run, least-squares refit after it
- Start and finish moments interpolated, roughly ±0.05 s
The curve beside you is a real run, exported from the app.
After the run
This is what
you did.
Every run is stored with its full speed curve, G-force trace and the conditions it was set in, so you can go back to any launch and see exactly what the car did — not just the number it ended on.
- Speed chart with split markers
- G-force trace and peak G
- Dry, damp or wet conditions per run
- Every run kept, on the device
Your garage
Bring your
whole garage.
Every car, bike or van you drive, each with its own photo and licence plate. Dutch plates pull their registration details in automatically. Every run is filed against the vehicle that did it, so your times never get mixed up.
- A photo and licence plate per vehicle
- Cars, motorcycles, vans — anything you drive
- Dutch plates looked up automatically via the RDW
- Personal bests kept per vehicle
Gauge styles
Pick the dial
you want to watch.
Four faces, switchable per run. Classic is the readable one you can take in at a glance; G-Force swaps the speedometer for a live accelerometer readout showing exactly how hard the car is pulling.
Drag the dials to browse them, or pick one above.
