Measure live, save your runs, compare them.

The app times you in real time using GPS data – far more accurate than manual timing. A live graph shows your speed during the run.

0–100, 100–200 or a fully custom range. Switch between km/h and mph at any time.

Automatic split times every 50 km/h show you where your car is strong and where it loses time.

Built-in G-force meter with a live display. Every run also stores its maximum G-force and top speed.

Measure braking time and braking distance in a dedicated brake test mode.

Personal bests are compared automatically. Put two runs side by side with delta values and a map of both routes.

All runs are saved. Detailed statistics show the best and average per range as charts. Use tags and categories to filter your measurements.

Export runs as CSV, GPX or text and share saved measurements through other apps.

3-2-1 countdown with haptics, optional spoken speed announcements and a GPS accuracy indicator with color feedback. Plus light and dark mode.
