Do the smart stylus features work on all iPads?

The features of the smart pen work on several iPad models featuring Bluetooth® Smart technology:

• iPad 3 and 4

• iPad Mini 1, 2 and 3

• iPad Air 1 and 2

The Bamboo Stylus fineline is not optimized for either the iPad Air 2 or the iPad Mini 3, but we are currently working on a solution that will improve the experience within supporting apps. Our app partners will be responsible for implementing the updates in their app releases.
