This richer content is available for the NFL (American Football), NBA (Basketball), and multiple football leagues (EPL, Bundesliga, Serie A, La Liga, Champions Legue, Ligue 1, MLS, and more). The exact content available varies from sport to sport, but as a minimum includes statistics, performance breakdowns, and scoring information. Also notable are the improved player profiles, which, as well as including more information than in earlier version of the app, now include the ability to follow tweets, top stories and more for popular athletes.
Bing Sport's Live Tile is now more personalised and pin-worthy, displaying information about upcoming, live, and completed games for sports teams that you have marked as favourites in the app. The same favourites-based personalisation is used in the news section of the app, which means you are more likely to see content you care about.
There are also a number of smaller updates to the app user interface, including the addition of the ability to share content via messaging and social media (news stories and match information).
