Redline: 0-100 & Speed Tracker

Measure your car, keep every personal best and relive each trip on the map — all from GPS. Always obey traffic laws and speed limits.

Redline turns your iPhone into a performance meter for every drive.

MEASURE • Acceleration: 0–10, 0–50, 0–100 km/h, 0–60 mph, 0–200 km/h and 80–120 km/h — timed automatically from a standstill with 1/100 s precision • Top speed, average driving speed and your most driven speed • Peak acceleration and braking g-force • Altitude, climbs, longest and shortest trips, total distance

ONE DASHBOARD Every metric on one page with a live speedometer, gauges, bars and charts. Turn your phone sideways for the Pro landscape dashboard: pick 7 metrics and let the smart card follow your drive.

AUTOMATIC TRIPS Mount your phone and drive. Trips start by themselves and finish after you park — with a quick confirmation.

PERSONAL RECORDS Every metric keeps its own personal best and history, just for you. Speed and acceleration results are never ranked against other drivers. Game Center leaderboards and achievements cover only distance, trips, drive time and altitude.

SHARE Share any result with a beautiful card and a link to the app.

MORE • Lock Screen and Dynamic Island live trip (Pro) • Drive Display: a full-screen speed and map cluster for cars without a display behind the wheel, like Tesla Model 3/Y — with HUD mirror mode (separate purchase) • CarPlay trip screen • History of every best result • Metric and imperial units

Redline Pro: no ads, every metric, landscape dashboard, Lock Screen live trip and unlimited history — one-time purchase.

SAFETY Redline is a measuring tool. Always obey traffic laws and speed limits. Performance runs belong on closed tracks only. You are solely responsible for complying with the laws where you drive.
