doefom, That's by far the shortest @statamic addon I have ever coded, fitting on one single screenshot. It's a #Statamic wrapper of the #Laravel package "browser-detect" by "hisorange". You can use it to find out all sorts of stuff about the requesting browser and device or render content for specific devices only.
Original package: https://github.com/hisorange/browser-detect
