DO NOT BUY THIS APP!
Air Stylus has been superseded by Air Display 3. We are leaving this version in the App Store for backward compatibility. If you are a new customer, please buy Air Display 3 instead. It has all of the features of Air Stylus, plus a whole lot more, including a USB connection, support for the latest pressure-sensitive pens, and much faster performance.
Already have the Air Stylus app? Please download the Air Display 3 Upgrade Bundle. It includes both Air Display 3 and Air Stylus. If you have already bought this app, the upgrade should be FREE (in most countries, depending on foreign exchange fluctuations). The bundle also installs Air Display 2, but you can delete that after it gets installed.
Seriously, please dont buy this app. It doesnt run on iOS 9, it doesnt support a USB connection, it doesnt support the latest pens, and were not going to update it for the iPad Pro or the Air Pencil. Please buy Air Display 3 instead. Its the same price, and its better.
