Import native .uni sessions and TSV/CSV exports for lap times, sectors, GPS, speed, RPM and available sensor channels.
04 / ANALYSE
Lap and sector analysis
Review every lap, theoretical pace, trends, racing lines and synchronized telemetry at the exact point on track.
05 / COMPARE
Session comparison
Compare saved sessions, laps, sectors, GPS lines and telemetry with clear current and reference traces.

Engine and driver progress
Track engine runtime and rebuild targets alongside sourced reference times, season statistics, fitness and reaction training.
Telemetry that stays connected to the track
See where the lap was won—or left behind.
Scrub or play through a lap while the cursor moves across the telemetry graph and GPS trace. Compare another saved lap at the same track position, then zoom in to inspect the racing line.
- Speed, RPM, temperature, steering and available G-force channels
- Logger sectors, elapsed time and live time delta
- 0.5×, 1× and 2× synchronized lap playback
- Onboard video aligned with lap, telemetry and track position
Available detail depends on the channels recorded in the selected logger file.

Local-first by design
Your race data stays with you.
RaceMetric works without an account and stores sessions, logger data, notes, photos, onboard footage, fitness entries and preferences on the device. Backup and sharing happen only when you choose them.
The app may download read-only published reference-time data and request optional Open-Meteo forecasts. It does not upload your saved RaceMetric records to a developer-operated account system.
