At the top right of the screen there's a "hamburger"menu (3 horizontal lines on top of each other) which takes you to their products. Looks like it's been designed with mobile devices very much in mind... apart from putting the menu top right instead of top left as is the norm.
I went to the link from my desktop iMac and a normal website opens up for me. Looks and functions like it should and it doesn't have any mobile app bars etc. When I tried the iPhone it opened up optimized in the mobile app with the bars on the right. You holding your tongue in the correct cheek?
