Developers can now find out what devices users have to better tailor app content

Using the Graph API, developers can retrieve a list of devices that a user has connected to Facebook.

Not only will developers be able to gain insights about their audience, but an app can use this information to tailor in-app content to users of different devices. For example, a canvas game looking to prompt users to download the mobile version can easily determine whether a user should be given an App Store link or a Google Play link.

Developers can also now restrict user-to-user requests based on device by using the “multi-friend selector.”
