Three things StreetChrono does every session, automatically.
Cross your start/finish line and StreetChrono splits every sector automatically — accurate to the meter, with no trackside transponder.
Your phone's IMU becomes a lean angle sensor, corner by corner — see exactly where you're leaving degrees, and time, on the table.
Every ride becomes a session — speed traces, sector deltas, and personal bests you can replay once you're back in the pits.
Get early access before StreetChrono opens to the first track-day beta group.
