The latest high-profile artist app is for Frank Sinatra, to celebrate what would have been his centennial year. A joint venture between Universal Music and the singer’s estate, it’s being billed as – and we’re afraid you should steel yourself for this – an “appumentary”. Even so, the actual content looks good, with the app telling the take of Sinatra’s career through family and friends, as well as photos, concert footage and radio recordings. The app also integrates Sinatra songs bought from iTunes OR streamed from Spotify, Rdio or Deezer by premium subscribers to those services. Developer PlayDef designed and developed the app, which has been made available as a free download for iOS and Android. And if you’re still gritting your teeth at “appumentary”, remember that in 2010, one startup seriously attempted to rebrand album apps as “appbums”.
