Blizzard has rolled out a new mobile esports app for Android and iOS devices called—wait for it—the Blizzard Esports Mobile App. The app provides schedules, news, and scores from Hearthstone, Heroes of the Storm, Overwatch, StarCraft, and World of Warcraft events from around the world, and will also serve up notifications of announcements and upcoming competitions.

The app is simple enough: When you first fire it up you'll select which games you want to follow, whether you want to show or hide scores (to avoid spoilers if you're not watching live), and whether you want to receive push notifications. After that, you'll be taken to the main screen, which has a dedicated news page, scores for past events and a schedule for upcoming matches, and information on Blizzard's various leagues.
