Everything the show needs

One clock for the entire production.

From doors to curfew — timed, colour-coded, and shared across every device in the building.

Three timer modes

Run any slot as a wall clock, a countdown, or a count-up. Switch per slot, set durations, and let it auto-advance through the show.

Warning & over states

The whole screen shifts amber → yellow at your warn threshold → red when a set runs over, with a full-bleed flash legible from the back of the room.

Per-slot run of show

Build the whole timetable — doors, changeovers, sets, curfew — with types, notes, offsets, and file attachments on each slot.

Multi-day timetables

Program festivals and overnight events across multiple days — each day its own run of show, rolling cleanly through midnight without breaking the clock.

Location weather & temp

For outdoor shows, pull live conditions and a temperature readout for your venue location — so stage and crew can read the weather at a glance.

3-second crew sync

A master/viewer model: the stage manager runs the clock, crew open a share link on any phone and see the same time in under three seconds. No app, no install.

CSV · JSON · iCal I/O

Import an advance from a spreadsheet, export the run of show to CSV, JSON, or iCal, and hand it to the next crew clean.

Wake Lock & web push

The screen never sleeps mid-show thanks to Wake Lock, and web-push cues fire to the right people at the right moment.

Installable PWA

Show Clock installs as an app and keeps the clock on your home screen — full-screen, distraction-free, ready before doors.

Run of show

Every slot, timed to the second.

The timetable drives the clock.

Lay out the night — doors, opening act, changeovers, headliner, curfew — and Show Clock runs it. The live slot is highlighted, past slots dim, and the next cue is always in view.

Slot types colour-code automatically — sets in amber, breaks in green, changeovers in blue.
Countdowns, alert cues, notes, and file attachments live on each slot.
Auto-advance rolls into the next slot so no one has to touch the desk.

Master & viewer

One link. Everyone on the same time.

Who runs on it

Built for anyone running to a clock.

Front of house

Keep the headliner to curfew with a countdown the whole stage can read at a glance.

Stage & monitor

Good to know

Frequently asked questions.

What is Show Clock?

Show Clock is a full-screen stage timer and run-of-show tool for live events. It shows the current time, counts a set down or up, warns you before curfew, and keeps your whole crew on the same clock.

How does crew sharing work?

It uses a master/viewer model. One device runs the timer; everyone else opens a share link in a browser and sees the same time updating in roughly three seconds. No account or app is needed to view.

Does the screen stay awake during a show?

Yes. Show Clock uses the browser Wake Lock API to keep the display on while the clock is running, so it won't dim or sleep mid-set. It also installs as an offline PWA.

Can I import and export my timetable?

You can import a run of show and export it to CSV, JSON, or iCal — so an advance from a spreadsheet drops straight in, and your schedule hands off cleanly to the next crew.

What are the warning and over states?

Each countdown has a warn threshold (e.g. two minutes). The whole screen turns yellow at the warning and red when the set runs over, with a flashing border that's readable from across a venue.

Is Show Clock free?

Show Clock is a premium tool. It's a one-time purchase through Gumroad — no subscription — and unlocks on your Squaresmile Tools account, bound to your license.

Never run over again.

Open Show Clock, build your run of show, and put the whole crew on the same clock.
