Show Clock

Show Clock runs your running order: the list of everything that happens tonight and when. It shows a big clock for the room, tells the crew which slot is live and what is next, and lets the band, FOH or the promoter follow along on their own phones through a share link. When the show runs late, you shift the whole schedule with one button and every screen updates.

Who it is for

• Stage managers and tour managers who own the timeline and need one place to see doors, changeovers, sets and curfew.
• FOH and monitor engineers who want the countdown to the next changeover on a spare screen.
• Bands and support acts who keep asking "when are we on?" — send them the link instead.
• Festival stages running several days: keep one rundown per day and switch between them.

What makes it different

• The offset. Running twelve minutes late is one tap. Every upcoming time shifts at once, for you and for everyone on the share link, and the original planned time stays visible in faint text.
• Three clock modes per slot. Wall clock for schedule-driven shows, count-up for "how long have we been in this", countdown with alert and auto-advance for strict changeovers.
• Sharing that needs nothing from the viewer. No account, no app, no install. A link or a QR code on the wall.
• Works offline. The operator side is a PWA with a local cache; the clock never depends on the network to keep time.
• Paste a schedule. One line per slot, HH:MM Label, straight from a call sheet or a spreadsheet.
