## What is Shutter PJLINK?

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.

Key features
Add and manage up to 5 projectors (IP + optional PJLink password)
Duplicate IP prevention
Multi-select projectors and send commands in parallel
Open/Close shutter control with clear per-projector results
Visual status indicators:
Connection state (connected, disconnected, checking)
Shutter state (open, closed, unknown)
Automatic periodic status refresh
Built-in in-app Help
Apple Watch support with synchronized mode and projector selection in Direct only mode
Interface languages: English, Spanish, French, Galician, Basque, Catalan
Network
