Gucci has created a new free App for the iPhone and iTouch. It not only has the Gucci Little Black Book city guide, the latest fashion shows, look books and news from Gucci, but it also has some cool music features as well. Frida Giannini and Mark Ronson worked together to make Gucci Beats – a feature where you can mix your own music tracks and send them to friends – and personal playlists by Frida and Mark as well as a music stream channel. It’s available now at the App store.
