How a live screen updates

  1. Phone

    • Remote: +1, next slide, timer

  2. One tap

    OwnScreen API

    • Applies the change
    • Schedules and broadcasts

  3. Checked every 3 seconds

    TV

    • Paired by a 6-digit code
    • Shows the new state
A plain sign skips all of this: the whole display lives in its link. Live screens add the phone remote, schedules, and broadcasts.

Operating problem

A queue number, menu, or welcome sign on a TV usually means signage hardware, a player app, or slides someone edits by hand. Those setups break down on the small changes a day brings.

What changed

The whole display lives in its link, so a plain sign needs no account and nothing is stored on a server. Signed-in screens can go live: a TV pairs by code, follows a phone remote within seconds, and can switch on a schedule or show a broadcast sent to a group of screens.

System scope

  • Editor with live preview, QR codes, and ready-made sign pages
  • Live screens, TV pairing by code, and a phone remote
  • Schedules, broadcasts, screen groups, and image uploads
  • Email-link accounts and Stripe plans on Cloudflare Pages and D1

Technical constraints

  • Keep a plain sign entirely in its link, so showing it never calls the server or stores the message.
  • Let schedules, broadcasts, and remote presses reach a TV on its next poll, with no background jobs and no lost presses.
  • Change a plan only through Stripe's signed webhook, then trim live screens to the new plan's limit.
