The Wallpaper* HTC Global Design Tours app provides inspirational content from the most cutting-edge design cities of the world. Curated by international and influential designers, it is a well-informed insiders’ edit of must-see and must-do locations from the cities that host the top international design fairs. A suggested music track accompanies each location to create a more immersive experience for design fair visitors and city travellers alike. The app is optimised for the new HTC One, HTC’s latest handset and the world’s first smartphone with a zero-gap full metal unibody design.
