iOverlay

iOverlay is a Windows overlay for iRacing: standings and relative boards, a fuel calculator, track map, multiclass traffic indicator, and a simple Twitch chat integration, configurable separately for practice, qualifying and race sessions. The free tier covers the core overlays with fixed layouts; a Pro subscription unlocks full customization, a pit entry/exit helper, an incident-warning spotter overlay, a race control panel, and team fuel sharing.

The app doesn't publish a dated changelog or version history page, so the evidence here is the installer file's own last-modified timestamp rather than a release note.
