LapPulse Timer

LapPulse is the ultimate lap timer for kart drivers — precision telemetry in your pocket.

REAL-TIME LAP TIMING Connect your RaceBox Mini via Bluetooth for 25Hz GPS-based lap detection with automatic start/finish line recognition. See your current lap, best lap, and live delta in real time on a heads-up display designed for the track.

3 HUD LAYOUTS Choose from Neon Grid, Racing Cockpit, or Clean Brutalist — each available in landscape and portrait orientation. Mount your phone on the wheel or dash and get the data you need at a glance.

LAP COMPARISON Compare any two laps side by side with synchronized speed and delta charts. Scrub through the data and see cursor positions move on the track map in real time. Find where you're gaining and losing time.

SPEED ANALYSIS Color-coded speed heatmaps overlay your racing line on a satellite map. Instantly see braking zones, corner speeds, and acceleration points.

TRACK MANAGEMENT Create and manage your favorite tracks with a guided editor. Set start/finish lines and sector boundaries with precision using draggable pins and visual trigger zones.

PERSONAL BESTS Track your PB progression across sessions for every track. See your improvement over time and celebrate new records.

SESSION HISTORY Every session is saved with full telemetry data, weather conditions, and tags. Filter, search, and review your driving history.

SHARE & COMPARE Export sessions as .lappulse files to share with teammates, or export CSV for external analysis tools.
