What it does
Four things, done properly
GPS speedometer
Speed read from satellite positioning, not the wheel-speed sensor your dashboard uses. Average, top, distance, altitude, duration and time stopped for every drive.
Radar map
Speed camera and traffic-signal locations plotted along the route you are driving, with a countdown as you approach. Coverage depends on the underlying location data.
Trip history
Every recorded drive kept in one list with its own stats, so you can compare a commute week to week instead of guessing.
Ranks Pro
A global leaderboard by top speed, distance and trips, plus a profile that carries your own records.
AI Garage Pro
Preview paint, wheels and body kits on your own car with AI, and keep the results in a garage on your profile.
Feed Pro
Post a drive or a car, follow other drivers, and see what they are building.
Inside the app
Six screens you will actually use
Your dashboard is allowed to lie to you
Under UN Regulation No 39 a car’s speedometer may never read below true speed, but it may read up to 10 % + 4 km/h above it. GPS has no such licence.
Guides
Sourced answers, not filler
Tyre Size and Your Speedometer Accuracy
Changing your tyre's diameter alters its rolling circumference, directly affecting your speedometer's accuracy and potentially leading to significant speed discrepancies.
Radar, Lidar, ANPR: The Tech Behind UK Speed Cameras
Speed cameras use radar, lidar, or ANPR to measure your speed; radar uses radio waves, lidar uses light pulses, and ANPR calculates average speed over distance.
Speed Camera Tolerances: What Drivers Face Globally
Drivers face varying speed camera enforcement thresholds and margins of error across countries, from strict no-tolerance policies to allowances based on percentages or fixed values.
