Load-in, show days, load-out: every hour of a crew spread across a venue, on one list.

• ✓

  Who arrived: a tag, a QR code or a PIN at the venue door; the list fills as they come.

• ◎

  Who is where: a check-in from outside the venue's fence shows with a flag.

• ⇪

  What got done: each task closes with a time and a photo.

• !

  Who confirmed: who read the briefing and acknowledged it, who has not opened it.
