What's the Best Free Tally Light App for iPhone?

Cue Light. Open Safari, go to cuelight.io/app, scan the QR code — your iPhone is a tally display instantly. No App Store download, no server, no hardware.
⚠ Use Safari, not Chrome

Safari on iPhone supports Wake Lock (screen stays on automatically). Chrome on iOS does not support Wake Lock — your screen will dim mid-production. Always open Cue Light in Safari on iPhone.

How to set up on iPhone

  1. Open Safari on the iPhone you'll use as the display Not Chrome — Safari only for Wake Lock support.
  2. On the controller (your phone or laptop), open cuelight.io/app A room is created automatically. You'll see the QR code and a "Copy Display Link" button.
  3. Scan the QR code with the iPhone camera Or paste the display link into Safari manually. The screen goes fullscreen black — connected and on standby.
  4. Tap Live on the controller The iPhone goes fullscreen green. Tap Preview for amber. Tap Off to clear.

Browser compatibility on iPhone

Safari (iOS 16.4+) ✓ Full support — Wake Lock works
Safari (iOS 14–16.3) ⚠ Works, but no Wake Lock — screen may dim
Chrome (iOS) ✗ No Wake Lock — screen will dim
Firefox (iOS) ✗ No Wake Lock — screen will dim

For older iOS without Wake Lock: go to Settings → Display & Brightness → Auto-Lock → Never before your production. Remember to change it back afterward.

Why most iPhone tally apps require a server

Most tally systems communicate over a local WiFi network. The iPhone connects to a server running on a PC on the same network. This means:

Cue Light skips the server entirely. The signal travels over the internet — same as a text message. The iPhone can be anywhere with a data connection and the tally still works.

More questions

Does it work over cellular (not just WiFi)?

Yes. The display iPhone can be on cellular data, WiFi, or any internet connection. The controller and display don't need to be on the same network.

Can I use an old iPhone as a dedicated tally display?

Yes. Any iPhone running iOS 14+ and Safari works as a display. An old iPhone 8 or iPhone X running on WiFi is a perfectly good dedicated tally display at zero cost.

Can the iPhone also be the controller?

Yes. Open cuelight.io/app on any iPhone in Safari — it loads as the controller by default. Tap Live, Preview, Standby, or Off to control all connected displays.

How many iPhones can I connect at once?

Multiple. You can have several iPhones (or any other devices) connected as displays simultaneously — one in the talent's eyeline, one for a remote guest, one for the camera operator. All update at the same time.
