LeftLane
A precision driver’s log — every drive, measured.
v1 · launching August 2026
The problem
Most driving apps give you vibes — a needle that looks fast and a screenshot you can’t trust. LeftLane is for the people who actually pay attention: drivers who want real numbers from a drive, not a highlight reel. The hard part is turning a phone’s noisy GPS and motion sensors into telemetry you can stand behind — accurate, repeatable, and honest about its own limits.
What it does
LeftLane records a driving session and turns raw sensors into clean, trustworthy telemetry. It blends your phone’s GPS and motion sensors, on the device, into one smooth and accurate live stream — calibrated for each car so the g-force numbers are real, not noise.
Three ways to record: Free Drive (manual), Challenge (it routes and times you to a computed finish line against your personal best), and Hands-Free (the phone stays in the mount and starts itself). Every session gives live speed, an auto-detected sub-second 0–100, max G, distance, elevation, and hard-accel / hard-brake timelines.
Sessions live in The Garage, one per vehicle, with personal bests. You can share a drive live with a spectator view, and prove a result with a verified, tamper-proof share-card — because screenshots lie and cards don’t. It’s built privately, too: on-device licence-plate blur, biometric lock, exportable data, real account deletion, and an offline buffer that survives tunnels.
Key features
Built into the system.
Three recording modes
Free Drive, Challenge — routed and timed to a computed finish line vs. your best — and Hands-Free auto-start. Press start, or don’t.
Real telemetry, measured on-device
Your phone’s GPS and motion sensors, blended on the device into one smooth, accurate stream — calibrated for each car so the numbers are real, not noise.
Metrics that mean something
Live and max speed, auto-detected sub-second 0–100, max G, distance, elevation gain, and hard-accel / hard-brake event timelines.
The Garage
Every session belongs to a vehicle, each with its own personal bests — a real logbook, not a feed.
Live share & verified cards
A spectator view with a QR code and viewer count, plus tamper-proof result cards. Read the needle, not the screenshot.
Built thoughtfully
On-device licence-plate blur, Face/Touch ID lock, exportable data, real account deletion, and an offline buffer that survives tunnels.
02 Inside the app
Every screen, measured.
Live telemetry you can trust, results you can prove, and a garage that remembers every personal best.

Behind it
Telemetry, not vibes. The visuals here are rendered in LeftLane’s own instrument-cluster identity — its loud voice, not the studio’s calm one. A paid app with a subscription, launching v1 in August 2026.
