We talked about the Air Display app for the first time in mid-2010.
It is an app to turn your iPad, iPhone or iPod touch into a second monitor, making it a beautiful companion for your Mac / PC.
Since then, it has improved a lot, gaining support for HiDPI resolutions, compatibility with the iPhone 5, among other things.
Despite having a very competitive price (US $ 10) in my opinion, the value can drive away those who are in doubt whether it is worth or not to purchase the app.
Problem solved: Avatron Software has now launched the Air Display Free.
We are talking about the same Air Display all the features are present, however, supported by ads.
It's a great opportunity for those who wanted to test the app before hitting the hammer! It is universal compatible only with iPads, requires iOS 5.0 or higher and costs nothing in the App Store (23.8MB).

Update
Initially we said that it was also compatible with iPhones / iPods touch, but no, the free app only runs on iPads.
