LilDisplay vs OpenDisplay

LilDisplay — Turn your iPhone or iPad into a touchscreen Mac display Give your Mac a second screen you can actually touch — and control. No extra hardware, no subscriptions. Just your device, a free Mac app, and you're set. Super-fast — USB for 5–10ms latency, or Wi-Fi for wireless freedom. Touch your Mac — Tap, scroll, and drag right on screen. Take full control — Use your iPhone or iPad as a keyboard and mouse for your Mac. Even run it lid-closed, with your device as the only controller. A true external display — Extend your desktop and run fullscreen apps. Works everywhere — iPhone and iPad, back to iOS 15. FEELS LIKE A MAC TRACKPAD Swipe with three or four fingers to switch Spaces, open Mission Control or App Exposé. Download the free Mac app at lildisplay.app Requires iOS/iPadOS 15+ and macOS 14 (Sonoma) or later.

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. OpenDisplay is open source under the GPL-3.0 license.
