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.

  2. Start your sim and SimHub — the pit wall opens on your PC at localhost:8080.
  3. Open it on any screen — a second monitor, a tablet or a phone on the same network.
