The focus@will app streams music that is intended to boost your concentration. To develop the app, the focus@will team worked with neuroscientists at UCLA to understand how music influences motivation, and which types of songs, playlists, and genres encourage people to enter "the zone" where they're most productive. All of the playlists are designed so they don't distract you, meaning there are no songs with vocals or saxophone solos, for example. Songs are chosen to help you focus, concentrate, and get into the flow of working. The service offers a variety of genres.
