BluOS™ Announces 4.0 Mobile Application Update

BluOS 4.0 app on 2 iPhones

A stunning redesign of the interface in the 4.0 update brings a fresh perspective to the BluOS app experience

ISE, BARCELONA, SPAIN, JANUARY 26, 2023 – BluOS™, the premium multi-room music management platform by Lenbrook International, announces a new and improved BluOS 4.0 update to its mobile application platform. A preview demonstration of BluOS 4.0 will take place at the Integrated Systems Europe conference in Barcelona, Spain from January 31st – February 3rd, ahead of its public launch in the spring of 2023. For over a decade, BluOS has positioned itself as the industry leading, multi-room hi-res music control platform underpinning notorious hi-fi brands such as Bluesound, NAD Electronics and PSB Speakers. The 4.0 mobile app updated revives the BluOS app experience with cosmetic enhancements such as a cleaner layout, easier access around its navigation and menus, and customization options to suit individual listening needs.

An all-new home screen display in the BluOS 4.0 update is an exciting way to start the listening experience. A sleek, tile-based layout provides easy access to users’ most frequently listened-to stations, music selections, recently played, services, news, updates and more.

A relocation of the navigation bar placement to be at the bottom of the screen will provide users with easier reach of the menu and one-tap access to the most important features of the BluOS app: Home, Favorites, Music, Players and Search.

A globally accessible Search feature will improve on the previous search function by providing a default music service selection based on the users’ listening behavior, making it significantly easier than before for users to navigate to the contents they’re looking for. For instance, if a user has only a single Music Service set up, the Search function will default to it. If they have multiple, the Search function will default to the one that was last browsed.

One-tap access to important features will improve the logical flow of the app and increase ease of use in areas such as music management, adding or removing Favorites, and accessing the Player Drawer and Play Queue.

Music Management
In the browsing view, a ‘+’ button on the top right will directly lead to Music Services, making it quicker for users to switch, manage and control streaming services.

Choosing Favorites
Adding to or removing from Favorites will be possible with one click by using the ‘star’ icon in top right corner of the Albums & Playlists page (if the Service provides the option).

Selecting Players and Play Queue
Controlling and managing players in the Player Drawer will be directly accessible with one click from the ‘Now Playing’ screen. A selector for the Now Playing / Play Queue will improve user experience when switching between both while a quality Indicator on Now Playing screen will toggle between the basic and detailed information.

“BluOS 4.0 brings added depth to personalized, multi-room hi-res listening” says Andrew Haines, BluOS Product Manager, “this comprehensive redesign of the mobile app interface reflects a commitment to delivering seamless user experiences for BluOS users.”

  • Easy-to-reach navigation and menus
  • One-tap access to search, favorites and more
  • A ‘home’ for your most recent and most frequently accessed music
