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 https://peetzweg.github.io/opendisplay — without it, this app has nothing to connect to. OpenDisplay is open source under the GPL-3.0 license.

Verdict
The clearest difference is in-app purchases: OpenDisplay at none against NinoPad's 3. OpenDisplay also leads on ratings volume (18 vs 1) and iOS requirement (15.0 vs 17.0). NinoPad's advantage is rating (5.0 vs 4.7) and update cadence (every 4 days vs every 8 days). On price, ads, monetization model and device support there is nothing between them.
