Every lap, automatically saved.
Analyze, compare, and improve — from anywhere.
A background app for Windows quietly records every Assetto Corsa lap — then your cloud dashboard gives you session history, telemetry overlays, statistics, and AI coaching in one place.
Why ACTracker
Most tools for Assetto Corsa telemetry require in-game mods, store data only on your local PC, or need manual file exports. ACTracker takes a different approach to all three.
vs. local storage
Your data is stored securely online the moment a lap completes. Reinstall Windows, switch PCs, or open a browser on your phone — your history is always there.
vs. in-game mods
ACTracker reads data directly from Assetto Corsa's shared memory interface — a standard, read-only channel built into the game. Nothing is installed inside AC.
vs. manual workflows
Open ACTracker once, race as normal. Every lap is recorded automatically — no exports, no file management, no clicking. Just drive and review.
Features
Five core tools — each one built to give you a clear, honest picture of how you're driving.
ACTracker samples seven channels at 30 Hz for every lap you drive. That density is what makes lap comparison meaningful — you can see exactly where your brake point shifted, not just that your time changed.
Dig into any session or individual lap with detailed breakdowns. See lap times, validity, sector splits, and full telemetry traces. ACTracker automatically marks invalid laps — cuts, penalties, and pit-lane transits — so your clean records stay accurate.
Your personal dashboard shows the full picture of your sim racing history: total laps, total sessions, valid lap percentage, favourite track, and most-driven car. Updates live when a new lap arrives.
Compare any two laps side by side — overlay their telemetry to pinpoint exactly where time is being gained or lost. Ideal for comparing your best lap to a slower one, or tracking improvement across sessions.
After each session, ACTracker's AI coach analyses your telemetry and provides personalised insights. It highlights corner-by-corner behaviour, identifies patterns in your braking and throttle application, and suggests specific areas to focus on.
Step by step
Three steps from install to your first insight. After that, ACTracker runs entirely in the background.
Install the ACTracker background app on your Windows PC and sign in with your account. It sits in the system tray and auto-starts with Windows — nothing to configure.

Transparency
ACTracker is a personal tool built for sim racers. Here is exactly what it does, what it stores, and what it does not do — no marketing fluff.
ACTracker is free for the core experience: cloud storage, session analysis, statistics, and lap comparison. AI coaching requires a paid tier at a fair price. No hidden costs, no surprise paywalls.
The background app reads only Assetto Corsa game data (lap times, telemetry, car, track). It does not access any other application, file, or system resource on your PC.
Your sessions and telemetry are strictly private. Only you can see them after signing in. Data is never shared with other users, third parties, or used for any purpose other than showing it to you.
Your race data is never sold, rented, or used for advertising. ACTracker has no advertising business model. The data exists solely for your own analysis.
AI analysis is performed using your stored lap telemetry. Your data is sent to an AI model to generate the coaching report and is not stored externally or used to train models.
I am actively building ACTracker. The app is not yet available to users, but it is nearly ready. When it launches, you will be able to download the background app, create a free account, and start tracking every lap automatically.
No spam. One email when the app is ready. Unsubscribe any time.

Built by one person
ACTracker is a solo project — built by a student developer who races in Assetto Corsa and wanted proper telemetry tools at a fair price. Read the story, the motivation, and what is coming next.
