Klop! - Disclaimer Device

Klop! wants to run the application in a browser that is suitable for the device, so that all users can feel the best user experience.

This feature forces users to run the browser that suits their device (chrome for android and safari for iphone).

My task is to make this happen, by checking the user agent that accesses the web, and redirects (SPA) to this page if the device and browser did not match.
