Race Readout turns raw motorsport data into the kind of analysis a race engineer actually uses. Instead of just following the results, you can break down a session lap by lap — speed, throttle, braking, gear, and cornering forces — and see exactly where time is won and lost. Built for fans who want to understand the race, not just watch it. TELEMETRY ANALYSIS • Per-lap traces for speed, throttle, brake, gear and more • Derived channels: longitudinal and lateral g-force and corner curvature • Inertial-frame track path reconstructed from positional data • Compare runs and laps to see the real differences between them SESSION TIMING & STRATEGY • Full results with clean, readable timing • Lap-time charts with outlier filtering • Sector times and pace breakdowns • Pit stops, race progression, and stint analysis • Highlight your favourite driver across every chart Race Readout is free, with every feature unlocked and it's powered by the public OpenF1 API. It is an independent, unofficial app and is not associated with, affiliated with, endorsed by, or sponsored by Formula One Licensing B.V. or any related entity. All series, team, and event marks belong to their respective owners.
