Is it possible to limit wifi network access to one specific app like chrome?

Hi,

Looking to offer free wifi to customers if they use "our app" which will be a browser like chrome.

They will be able to access to facebook.com and etc from our app but not from chrome.

I was thinking I can use whitelist system, and append a parameter to all outgoing urls from our app and detect whether the network is from our app or etc.

Is there better way?

Thanks.
