LapperSnapper

Find the time you're leaving on track!

LapperSnapper turns your GPS and logger data into the one answer that matters: which corner cost you, and why. Everything runs on your phone, between runs. No laptop, no upload, no waiting on a server.

CORNER-BY-CORNER, NOT JUST A LAP TIME
• Auto corner detection...every turn found from your GPS line, no setup, any track
• Per-turn time lost, ranked by cost, with the apex-speed deficit vs your best
• Speed and running delta by distance, two laps overlaid, synced to the map
• The g-g traction circle, how much grip you're actually using, from GPS alone
• Race Engineer coaching that tells you which corners to work next session

BRING YOUR OWN GEAR — ONE ENGINE BEHIND ALL FOUR
• AiM MyChron 5 / 5S / 6 — straight off the logger over WiFi, no cable to a PC
• RaceBox — drop in a .ubx capture
• GoPro — load the .mp4, LapperSnapper reads the GPMF telemetry track
• No hardware at all — just your phone's GPS, with a live predictive-timing HUD while you drive

EVERYTHING ELSE IN ONE APP
• Racing line on the map, colored by speed
• Ultimate lap and sector times
• Per-channel charts — RPM, speed, and more
• Video overlay player, plus export a lap clip with telemetry burned in (audio kept)
• Per-track history and personal bests
• Share any lap as a link

YOUR DATA NEVER LEAVES YOUR DEVICE
Analysis happens on your phone, not our servers. No account required for the free app, and it keeps working with no signal in the middle of a paddock. That's not a setting — it's how it's built.

FREE, FOREVER
Import from any source, full session analysis, lap comparison, the traction circle, and coaching on your biggest time-loss corner — no account, no card.

GO PRO WHEN YOU'RE CHASING TENTHS
Coaching on every corner, unlimited history, the live predictive HUD, video export, and cloud sync across devices. Try it free for 14 days — no card to start.

TEAMS — FOR ACADEMIES AND ANYONE COACHING A ROSTER
Eight drivers on eight phones is eight problems. Teams puts the whole roster on one engine.
• One roster — up to 15 active drivers, one owner, up to 4 coaches
• A real profile per driver: race class, kart number, guardian and contact details, your notes, and their whole history with you
• Young drivers need no account — add a name and start logging. They can claim the profile later, and every session comes with it
• Download the karts on one device and tag who drove; drivers with their own account share automatically
• Unlimited team session history, plus your team's branding on exported clips
• Coaches see the roster, a driver only ever sees themselves — fixed policy, not a per-team setting
Team 15 is $99/month or $990/year, bought in the app by the team owner. Cancel anytime.
