Your iRacing history, beyond a single session.
iRacing tells you how you did today — SlipTrace keeps the whole story. The Windows companion captures your laps while you race and builds a persistent, shareable history of every session. iRacing support is in active testing and available to try now.
Automatic capture
What SlipTrace records from every iRacing session
Every lap and sector
Lap times and sector splits captured live from iRacing telemetry, from practice to official races.
Personal bests by track
Fastest laps per track and car combination, tracked across weeks and seasons — not just one results screen.
Track and session context
Track, car, session type, and date — a searchable history that outlives the session window.
Automatic sync
Sessions are recorded locally while you race and uploaded once at session end. Offline sessions queue and sync later.
Review on your phone
Open the Android app after a race and your laps, deltas, and history are already there.
A shareable profile
Your best iRacing sessions become a public driver profile other drivers can follow, like, and comment on.
Common questions
iRacing and SlipTrace
How do I track my iRacing lap times across sessions?
Install the free SlipTrace companion on your Windows PC and race. It reads iRacing telemetry while you drive and syncs each finished session to your SlipTrace profile, building a lap history that persists across sessions, weeks, and seasons.
Is iRacing fully supported?
iRacing support is in active testing. Core capture — laps, sectors, session history — works today, and it hardens with every companion release. Assetto Corsa Competizione is fully supported.
Does SlipTrace affect iRacing performance?
No. The companion reads iRacing’s telemetry output — it never injects into the game process and has no measurable impact on frame rate.
Is SlipTrace free for iRacing?
Yes. SlipTrace is free during early access, with no paywall on core features.
