Desktop
LAP for desktop.
The desktop client captures every sim session you drive, gives you live reference signals while you are still in the cockpit, and ships race-night strategy tooling for the events where the lap-by-lap data is the whole point.
Sim capture
Every session, in real time.
Telemetry from iRacing, ACC (Assetto Corsa Competizione), and AMS2 (Automobilista 2) streams into LAP automatically. No file imports, no post-session paste. The session lands in your driver profile the moment you exit the cockpit, with weaknesses already flagged for the next drill cycle.
Live coaching
Rule-based reference, not a voice in your headset.
Live coaching here means signals you read at your own pace: lap-time delta against your personal best on this track plus car combo, sector deltas against your reference lap, and an optional in-cockpit overlay for the brake and throttle traces of the reference lap. The signals come from the rule library and the data from your own driving — no generated commentary, no chat-box trying to talk to you while you are at the wheel.
Strategy
Race-night tooling.
Endurance events and serious races run on the lap-by-lap numbers — pace targets, fuel stints, tyre management, the gap to the car ahead three corners from now. The strategy surface puts those numbers next to your live session so the call you make in lap 47 is the call the data already supports, not the call the spotter remembered.
Supported sims
The sims LAP captures from today.
-
iRacing
Official series, ranked multiplayer, the leagues serious sim racers run their seasons in. Telemetry via the iRacing SDK; an active subscription is required.
-
Assetto Corsa Competizione
GT3 and GT4 racing, endurance formats, the Blancpain-derived car set. Shared-memory telemetry; one-time purchase, no subscription.
-
Automobilista 2
Formula, stock cars, prototypes, and a broad track list including the Brazilian circuits. Shared-memory telemetry; one-time purchase, expansions sold separately.
System requirements
What you need on your rig.
- Windows 10 (build 1809 or newer) or Windows 11, 64-bit. Sims live on Windows, so the desktop client does too.
- About 200 MB of disk for the installer and the local cache, plus 200–300 MB of RAM on top of what the sim already uses. The capture path is a thin overlay; it does not steal frames from your sim.
- An internet connection for first sign-in and for cloud sync of your driver profile. Capture itself works offline; the session uploads on the next reconnect, so a flaky home network does not lose data.
macOS support is on the roadmap but not shipped. If you race exclusively on a Mac today, LAP is not for you yet — we would rather say so than have you waste a trial.
