LinkedIn's mobile website seems to know if users have installed their app, regardless of whether they're logged in.

This SO post addresses how to determine if a user has an iOS app, but this requires Objective-C.

How can you replicate the LinkedIn functionality, and determine from a website, whether users have installed a specific app?

Is LinkedIn just relying on a sophisticated cookie system? If so, how do they tie the cookie to a unique device and app installation?

We assume there isn't some new programmatic way of querying an iOS device for a list of installed apps?
