About Sleeve: Album Player
Sleeve is a quiet way to listen to whole albums. Open it and you see one thing: a slow, full-screen wall of your album covers. Tap a cover and the whole album plays from the first track, with no playlists, shuffle or endless feeds. Turn the phone to landscape for Album Flow, which glides through your library one cover at a time. A music subscription is required to play your library.
Version 2.1 adds full-screen layouts on both iPhone Duo displays and keeps the album wall in place through folding and unfolding. In landscape you choose the wall or Album Flow, and portrait uses the wall.
