No Razorline account, no ads and no tracking. Sessions and telemetry stay on your phone; maps and purchases use the platform services described in the policy.
Three modes to start the timer perfectly.
Press Start and the time begins instantly. The lap closes when you cross the finish line again.
Starting grid style: the timer starts exactly when the lights go out.
Arms automatically near the line: the time starts the moment you cross the start line.
The developer does not receive, sell or use your session data for tracking. Location, Bluetooth and sensors power local features; maps and purchases use the official Google, Apple and store services described in the policy.
