Try every overlay first.

LapVoice for Windows, with simulated data, so you can build your screen before you spend anything. Live telemetry switches on with an activation code.

LapVoice Pro 1.3.0

Windows 10 or 11, 64-bit. 45 MB. No installer, no account, no Python.

LapVoice in preview mode: every overlay visible, each carrying a PREVIEW badge, all fed by simulated data.
Preview mode on a 1920 × 1080 screen. Every overlay is there; the data is simulated and every panel says so.

Install

  1. Extract the zip somewhere you can write to, such as Documents\LapVoice. Do not run it from inside the zip.
  2. Run LapVoice.exe. The control panel opens with every overlay unlocked.
  3. Arrange the overlays. Settings save automatically.

The control panel. Overlay options, units and the coach live here; nothing is buried in a config file unless you want it there.

Windows will warn you

The build is not code-signed yet, so Windows SmartScreen may say “Windows protected your PC” the first time. That is expected for a small independent app. Click More info, then Run anyway.

Some antivirus tools flag unsigned PyInstaller executables. If yours quarantines it, restore it and add an exclusion. If you would rather not, the free command-line coach is plain Python and needs no executable.

Preview mode and activation

Without a code, every overlay is marked PREVIEW / NOT ACTIVATED and the app uses simulated data. That is deliberate: you can test the layout, size, opacity and options in the car or on the desktop, and nothing pretends to be live.

Unlocked: dashed outlines, a name tag and a resize handle on each panel. Lock them and every one becomes click-through.

Requirements

  • Windows 10 or 11, 64-bit.
  • iRacing, running in windowed or borderless-windowed mode. Exclusive fullscreen covers the overlays; VR is not supported.
  • For AI tips: Ollama with about 8 GB of graphics memory for the default model. Without it, every overlay still works and the coach falls back to built-in tips.

If something does not work

The app has a built-in diagnostics button that lists every telemetry channel iRacing is reporting. Run it before reporting a problem: troubleshooting covers the common cases, and hello@lapvoice.com reaches a person.
