Track detection and the coach briefing
Last updated Sep 25, 2026
LapperSnapper knows where you are. When you start a session, the app matches your GPS position against its track list and, at a circuit it recognises, sets things up for you.
What track detection does
- Names the session after the circuit automatically.
- Uses the circuit's surveyed start/finish line for lap detection, when the track list has one, so lap times are consistent with the timing board. Today only South Garda Karting has one; everywhere else the line is set where your GPS first locks.
- Connects the session to your history at that track, powering personal bests and progression.
No setup is required at known circuits. The built-in track list is still small, so at many tracks the app won't recognise the venue yet — a brand-new track or a temporary layout too. It still records and detects laps from your driving; see No laps were detected in my session if laps go missing.
The coach briefing
The coach briefing is a Pro feature — it needs a Pro subscription, a track the app recognises, and session history there. Track detection and basic lap timing stay free for everyone; only the briefing itself is Pro.
When those line up, the briefing names the track and the track area most worth focusing on by voice ("Today's focus: the corner in track area 3"), and a Focus line on screen shows how much time is on the table there during the session.
It turns your previous sessions into a plan for this one: instead of just driving laps, you go out with a target. During the session, the HUD keeps the focus area in view.
Track areas are numbered by LapperSnapper, by matching nearby corners across your sessions — they aren't the circuit's official turn numbers. The briefing draws on the same cross-session Race engineer findings you see in your track history.
