Shutter PJLINK
Utilities
$12.99
2 apps in 1: it installs on iPhone and Apple Watch, so you can control Shutter/PJLink from both with automatic sync between devices.
Shutter PJLink is a simple and reliable control app for PJLink-compatible projectors on iPhone, iPad, and Apple Watch.
It now combines two workflows in one app:
PJLINK Direct (iPhone/iPad): control projectors directly over PJLink.
Watch OSC: send Open/Close commands from Apple Watch with two operating paths:
Via Mac: Watch -> iPhone -> Mac running Shutter PJ-OSC
Direct only: Watch -> iPhone -> PJLINK projectors directly
The app is designed for real AV workflows where speed, clarity, and stability matter.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Improved compatibility with Shutter PJ-OSC on macOS.
OSC commands now use projector-specific routes (/shutter/open/N and /shutter/close/N) for more reliable control.
Added support for OSC password-protected setups: when configured, commands include the password as the first string argument.
Updated iPhone–Watch sync so OSC connection settings (including password) stay consistent across devices.
General stability improvements for relay mode communication
