Air Display 2: Use Your iPad or iPhone as a Second Monitor for a Mac or PC

If you're looking for a cheap way to add a second monitor to your workspace, or if you'd like to add touchscreen capabilities to your desktop, Avatron's Air Display 2 app may just do the trick. This app allows you to use your iPhone or iPad as a second monitor for your PC or Mac. It's pretty simple to use -- you download the app from the App Store, download the drivers for your PC or Mac, and get going!

You can use Air Display to create a true secondary monitor that expands your workspace to your phone or tablet, or you can mirror your main display on your device. Either way, Air Display also allows you to leverage your touchscreen to interact with your desktop, which we think is pretty cool. What's more, we've found that, especially over a wireless network, the app is pretty snappy -- there's little if any lag.

Pricing and Availability

Air Display 2 is available for iOS devices only, and it costs $9.99 from the App Store. It works with computers running Mac OS X or Windows 7 or 8, excluding Windows 7 Starter edition.
