LapperSnapper knows where you are. When you arrive at a circuit and start a session, the app matches your GPS position against its track database and sets everything up for you.

What track detection does

• Names the session after the circuit automatically.
• Uses the real start/finish line for lap detection, so lap times are consistent with the timing board.
• Connects the session to your history at that track, powering personal bests and progression.

No setup is required at known circuits. If you're somewhere the app doesn't recognise — a brand-new track or a temporary layout — it still records and detects laps from your driving.

The coach briefing

When the track is recognised and you have history there, the briefing tells you — on screen and by voice — the one thing most worth working on: the corner where you've been losing the most time, and how much is on the table there.

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 corner in view.
