GRIDUNION TOOLS

Choose the job.
Find the right tool.

Start with what you need today. Team planning works on the website; supported live data and recordings come from the Windows app.

WINDOWS APP · FREE BETA

The race data you need. Sized to read.

Choose your Relatives and Standings columns, increase their text size and arrange your overlays. Easy Mode keeps the starting choices small; Advanced Mode gives you more control.

For triples and streaming, place separate copies in your OBS layout without moving your driving overlays.

SESSION LOGGER & LAP COMPARISON · BETA

Find your best lap. See where you gained.

Enable recording in the app under Settings → Leaderboards & Lap Comparison, then drive an iRacing or LMU session. Completed supported laps upload while the app is running and connected. Open My sessions to review times, sectors, conditions and available traces.

  1. RecordConnect your account and enable recording before driving. Event training is optional.
  2. ReviewOpen a session and choose two laps. Missing traces or values remain unavailable, not invented.
  3. Choose what to shareTeam telemetry and global lap summaries are separate, opt-in choices. Manage an existing session’s sharing in its details.

A leaderboard time is not proof of identical conditions. Invalid and incomplete laps cannot claim records. Unverified LMU session provenance is labelled; it is never silently certified as official.

TEAM PREPARATION & RACE DAY

The plan belongs to the whole team.

Use the website for entries, availability and stint planning. Open Race Day from your team event; use the app’s Pitwall for supported live information. Team permissions decide who can act.

Long Runs

Guided iRacing practice for a specific team event. Collect fuel, pace and pit evidence automatically; check conditions yourself.

Requirements & training steps →

Race Day & Pitwall

Keep the active team plan and available live data close. Simulator coverage differs; stale or missing values are not live evidence.

Check simulator support →
DISCORD BOT

Driver replies. Race channels. Timely reminders.

Connect the bot to your team server, collect race-card responses and configure reminders. Managers choose channels and optional automation in Team Settings; drivers control their personal notifications.

Session summaries and record notifications

/sessions privately lists your five latest recordings. Team summaries and record alerts are optional and off by default. A summary is sent after five minutes without another uploaded lap and updated if activity resumes; that pause is not proof that the session has ended.
