A real race-team pit wall, on your second screen
A pit wall is the bank of screens a race team watches while the car is on track. SimRace.app gives you the same thing at home: it reads your sim's telemetry live through SimHub and turns it into the calls a race engineer would make — not raw graphs, the actual engineering.
Open it in any browser on a second monitor, a tablet or a phone on the same network. It updates every corner, every lap, hands-free while you drive.
What it shows
Live & laps
Delta to your best, sector colours, position, gaps, fuel level, tyre and brake temps — at a glance.
The balance bubble
Your load balance as a spirit-level bubble: which corner goes light, where the front won't bite — the hardest thing to feel, made visible.
Tyres & fuel
Hot-pressure window, the limiting tyre, wear and degradation, fuel and virtual-energy per lap, the optimal pit lap.
Strategy & weather
Pit scenarios, undercut windows, stint length and the weather trajectory — the strategy call, live.
Corner analysis
Understeer / oversteer by corner and phase, braking, apex speed — measured per wheel, not from feel.
Seven AI engineers
Chassis, tyres, data, strategy, energy, driver and a chief engineer who arbitrates them into one briefing you actually read.
Free, really
The 2nd-screen pit wall on your own PC is free, no subscription — plus 2 telemetry reads a day. Pro (9.99 €/mo) adds full setup engineering, session history and before/after deltas; the live remote pit wall (sharing your wall to screens and engineers anywhere) is a Team feature.

Frequently asked
- Is the sim racing pit wall free?
- Yes — the 2nd-screen pit wall on your own PC is free with no subscription, plus 2 telemetry reads per day. Pro unlocks full setup engineering and history.
- Which simulators does it support?
- Le Mans Ultimate, iRacing, rFactor2, RaceRoom and the Assetto Corsa family via SimHub. The balance / centre-of-pressure engineering is live on Le Mans Ultimate and rFactor2 today.
- Does it work on a phone or tablet?
- Yes — it runs in any browser on your PC, a second monitor, a tablet or a phone on the same network while you drive.
- Do I need to read graphs or code?
- No. The engineers compute the engineering and give you plain-language calls — it is not a raw graph overlay.
