Air Display lets you use a spare Mac’s screen as an extra display for your main Mac.
It's easy to use! Just launch this app on your spare Mac, then wirelessly connect to it from the free host app on your main Mac, to instantly expand its screen real estate. You can also connect with Ethernet, Thunderbolt, or USB-C.
IMPORTANT: This is NOT the free Air Display host software that you need on your main computer. You can download that at getairdisplay.com. This is the client app that turns a Mac into a second monitor for another computer.
— FEATURES —
• Drag windows, apps, or control palettes from your main screen to give yourself more room to work
• Use up to 4 devices simultaneously to extend or mirror your computer
• Choose to run full screen or in a window
• Either extend your screen to get more room to work or mirror to share your screen with an audience
• Connect via Wi-Fi or over Ethernet
— INSTALLATION —
You’ll need the free Air Display host app (from GetAirDisplay.com) installed on your main Mac, and this Air Display client app running on the Mac you want to use as an extra screen.
• Purchase this app on the Mac you want to use as your second display
• On your main computer, go to getairdisplay.com and install the free host app
If you want to use your iPad or other mobile device as your second screen, you do not need to purchase this app. Air Display for iOS is available in the iTunes App Store (and you’ll still need the same free host software from getairdisplay.com on your main computer).
— COMPATIBILITY —
• Both computers must be on the same Wi-Fi network, or connected via Ethernet, Thunderbolt, or USB-C
• Mac client app: iOS 6 and above
• Mac host: macOS 10.8 and above (macOS 10.13.4–10.13.6 not supported)
• The Air Display Host is not compatible with Windows
• Fixed some stability issues, including a couple of crash bugs
• Built for 64-bit Macs
• Updated the instructions to remove mention of the old Windows host
Be sure to update the host software to the latest version. The host software changes frequently.

Does what it says, but...
Set up was fine and fairly straight forward. But the performance leaves a lot to be desired. I suppose it depends on the speed of your wi-fi though, I have 4-5Mbs and it is obviously not good enough. I purchased it because I wanted to use it for GarageBand, running it on my MacBook Pro and using my iMac screen. However, the cursor response is far too slow to make it practical, so I've pretty much wasted my money until the performance is improved. Oh well, you live and learn. Overall, it's not a bad app by any means, it's just that it doesn't work very well unless you have very fast wi-fi.
Good results using ethernet cable
I'm using a new iMac 27, 3.4 Ghz quad core i7, with 16 G RAM as the host computer, and an iMac 21.5, 3.01 Ghz dual core, with 4G RAM as the slave display. The smaller iMacs (pre-thunderbolt) don't have a video-in point so normally can't be used as an additional display. However, I thought I'd give this app a go before ebaying it, and have been pleasantly suprised with the results. the 27 is running on Lion, the 21.5 on Leopord. With both computers connected to each other via an ethernet cable the performance is great. There is a little lag, but not bad at all. I've even been using this dual display set-up using Final Cut Studio applications (with the FileBrowser, Inspector, and Layers Tab all on the slave display - the lag is noticeable, but doesn't affect the efficiency of the workflow). I wouldn't want to use any apllications with intricte interfaces on the second display in wireless mode though - too laggy. Obviously this isn't as good has having a second display conected via your computer's graphics card, but, if like me that's not possible, this is a great compromise.
Nice idea that improves productivity.
Works well, although set up isn't as straight forward as implied. Make sure you know which you want as the remote. This consists of two software packages, the application from the apps store and another application which you load from Avatron. If you want your iMac to be the display for your Macbook Pro then load the app software from Avatron onto your Macbook Pro. The app store appication needs to be on both !!!
On my iMac I found that on start up, there was a bug that gave a broken up display for a few seconds before the main screen displayed correctly.
Work smoothly and gives me two screen with out paying for a Cinema display. Nice.
