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.

Turn your iPhone or iPad into a second screen for your Mac — wireless or wired, with Retina sharpness and full mouse and keyboard control. Expand your workspace or mirror your Mac screen in seconds. HOW IT WORKS WiPhoneMonitor consists of two parts: this app (free for iPhone/iPad) receives the video stream from the screen via the WiPhoneMonitor application installed on your Mac (available at wiphonemonitor.com). Download both, connect them via USB or Wi-Fi network, and you're ready to go. FEATURES - Extended Mode: your iPhone/iPad becomes a real extra monitor, not a mirrored copy - Mirrored Mode: project your Mac screen for presentations, classes, or demonstrations - Connect via USB cable (lower latency) or Wi-Fi - Mouse and keyboard control straight from your mobile device - Retina resolution and up to 60 fps on the Professional plan - HEVC codec for lower network usage and better quality - Adaptive video quality that automatically adjusts to your connection latency - Automatic reconnection with Wi-Fi health monitoring - Documented end-to-end encryption (AES-256 + signed handshake) - Works with iPhone and iPad — not just iPad - No dongle, no extra hardware, no accounts required (Apple ID, Google Accounts, etc.) WHO IT'S FOR - Anyone who works in a small space and needs an extra screen without having to carry a monitor - Developers and creators who want a second screen to increase their productivity - Anyone For those who present, teach, or give demonstrations and need to remotely control their Mac screen - For those who travel and want professional-level productivity with what they already have in their bag. VERSIONS WiPhoneMonitor has three versions — Basic, Advanced, and Professional - Basic: mirroring and extension via USB, ideal for occasional use - Advanced: adds encrypted Wi-Fi, HEVC, and standard resolution - Professional: Retina resolution, 60 fps, full adaptive quality, and a performance test LICENSE PLANS The iPhone/iPad application is free to download and connects to a licensed Mac application.
