ACTracker

ACTracker

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

Different by design

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

Cloud-based from the start

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

Zero game modifications

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

Fully automatic, zero effort

Open ACTracker once, race as normal. Every lap is recorded automatically — no exports, no file management, no clicking. Just drive and review.

Features

Everything you need to get faster

Five core tools — each one built to give you a clear, honest picture of how you're driving.

High-Resolution Telemetry

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.

  • Throttle position, brake pressure, and steering angle
  • Speed, RPM, gear, and lateral G-forces
  • 30 samples per second — precise enough to find corner-entry errors
  • Every lap stored permanently in your cloud history

Session & Lap Analysis

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.

  • Full paginated lap list — time, validity, track, car, and date
  • Automatic invalid lap flagging: track cuts, penalties, pit transits
  • Session overview: track, car, date, and track length at a glance
  • Valid lap percentage — a quick read of how consistent a session was

Personal Statistics

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.

  • Total laps and sessions at a glance
  • Valid lap percentage across your history
  • Favourite track and most-driven car

Lap Comparison

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.

  • Side-by-side telemetry overlay
  • Identify braking points, throttle application, and speed deltas
  • Compare across sessions, tracks, or cars

AI Coaching

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.

  • Post-session AI analysis powered by Claude
  • Corner-by-corner feedback on technique
  • Identifies braking, throttle, and consistency patterns
  • Written in plain language — not just raw numbers

Step by step

Set it up once. It tracks everything.

Three steps from install to your first insight. After that, ACTracker runs entirely in the background.

Download and install

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.

Fully automatic · No configuration needed

Review and improve

Open your dashboard on any device. Browse sessions, compare laps, check your statistics, and read your AI coaching report. No refresh needed — data updates live as laps come in.

Transparency

No hidden costs. No surprises.

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.

Free to use — AI features excepted

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.

Only race data is collected

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 data is private to you

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.

I do not sell your data

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 coaching uses your telemetry — nothing else

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.

ACTracker is in development

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.

Who is behind ACTracker?

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.
