Can’t you at least tell what is also required to run on iOS?


Bought this pricey app without being told I need to run iOS 6 to install Air Display 2 on my iPad first generation.

Wasted $20.

More trouble than it’s worth.


Mirroring displays is one of the most useful tools available out there today. Great technology that can seriously enhance productivity. Unfortunately this application fails on most levels. Not only is it too slow to even be worth having two screens, the second display is extremely choppy and nearly impossibly to scroll effectively.

Don’t get too excited about having one display showing a video of some kind while you are working or writing on the other screen because it fails at that too. Displaying videos is always completely out of sync. You could disconnect one display temporarily but than when you reconnect to air display it requires adjustments to get it back to the way you want.

The developers do a good job buttering this app up but you are much better trying to spend the additional cash to get a more effective dual display connection.

If you were wondering if the quality of computers matters, it doesn’t. I am using a brand new 2.7 Ghz iMac with a 2.3 ghz macbook pro. Two exteremely expensive computers. This application is nothing but a waste of time.

Software won’t run! crash on start

Bought the app and installed on my brand new MBP with touch bar running macOS 10.12.3
The application crashes as soon as I opened it. I was never able to even open it. Tried to contact Avatron, but heard nothing back.

Don’t waste your time on this app if you are planning on using it on your new MBP with touch bar running 10.12.3

I sent a request to Apple asking for a refund, and I’m waiting to hear back from Apple now.
