GPS 20Hz
The u-blox M10 module samples position 20 times per second, guaranteeing 50ms temporal resolution per lap — more than enough to distinguish hundredths of a second between sessions.

Intelligent analysis
AI Coach
At the end of each session, the AI analyses your laps and identifies where you are losing time: late braking, non-optimal trajectories, wrong apex points. Concrete feedback, not just numbers.

FAQ
Frequently asked questions
How does beta access work?
Fill in the request form. We evaluate each application based on the usage profile and will contact the selected candidates within 48 hours. Beta testers receive the device at a special price in exchange for structured feedback.
Do I need the device to use the app?
No. The app works with your phone's built-in GPS. The LapCoach device significantly improves accuracy by raising the GPS frequency from ~1Hz to 20Hz — the difference between ~5m and less than 1m of positional accuracy.
Which cars and motorcycles are supported?
LapCoach works with any vehicle. It requires no electrical installation — it mounts with velcro or zip ties in any position.
Which circuits are supported?
91 tracks preloaded worldwide — Italy, Europe and beyond. More are added with every update. And if your track is missing, you can add it manually directly from the app.
How is the device firmware updated?
Via the app over direct WiFi — no computer needed. The app notifies you automatically when an update is available.
Where do you ship?
We currently ship to Italy. Free shipping above €59.
