I love the Sonos products, they are a breeze to use and the product design is slick and clean. However, the software feels so outdated and the UX is clumsy. That's why I decided to redesign some of the screens and handeling of the app, for fun. One of the features I introduced is a vertical slider for the volume (feels way more natural then a horizontal one) which is also available from the navigation.
Note: this redesign is based on the old Sonos app, they already redesigned the old one.
