OpenDisplay
Use your iPad as a Mac Monitor
Free · Designed for iPad. Not verified for macOS.
OpenDisplay turns your iPhone or iPad into a second display for your Mac.
It's the open-source way to put your spare Apple device to work as a real extended monitor — drag windows onto it, keep chat, notes, or logs in view, and gain screen space anywhere you go. It's not a mirror: it's a genuine additional display your Mac treats like any other monitor.
• Real extended display — arrange it in your Mac's Display settings and drag windows across
• Connect over USB for the lowest latency, or over Wi-Fi with zero setup
• Retina-sharp, pixel-for-pixel rendering
• Touch and scroll — tap, drag, and two-finger scroll to control your Mac
• Works in portrait or landscape
• Private by design — a direct connection between your own devices, with no accounts, no servers, and no tracking
IMPORTANT: OpenDisplay requires the companion OpenDisplay app for Mac, running on your computer on the same cable or Wi-Fi network. Get it at opendisplay.app — without it, this app has nothing to connect to.
