Use Air Display to turn your iPad, iPhone, or iPod touch into a wireless display for your computer. Increase your productivity with extra screen real estate or mirror your Mac or Windows computer display to your iOS device.

For Mac users, Air Display now connects up to 4 iPads simultaneously to create unique presentations.

“You have a bunch of different options to turn your iPad into a second display, but we prefer Air Display as the easiest option.” — Lifehacker

With Air Display, you can wirelessly extend your computer desktop to gain more space or you can mirror your computer's screen to your iOS device and control your computer with intuitive iOS touch gestures and/or Air Display's elegant built in keyboard. Got a Bluetooth keyboard? you can use that too!

And with Air Display 2, you can even wirelessly mirror your screen to up to four iPads simultaneously to create unique training sessions or presentations.

Air Display consists of an iOS app and a separate free app that you install on your computer. Both your computer (Mac or Windows) and iOS client (iPad, iPhone, or iPod touch) must be on the same Wi-Fi network to use Air Display.

• Type using Air Display's built-in keyboard or any Bluetooth keyboard
• Use up to 4 extra screens at the same time (Mac only)
• Best performance of any app of its kind
