Blizzard is heavily invested in the esports market so it comes as no surprise that the developer just launched an app that focuses on this industry. The Blizzard Esports Mobile App, which is available on both iOS and Android, brings things like scores, schedules, and other game-centric updates in the similar vein as the NBA app does for the game. It currently supports the tournaments for titles like Overwatch, Hearthstone, Heroes of the Storm, StarCraft, StarCraft II, and World of Warcraft. But it must be noted that the Overwatch League isn’t included here. Perhaps in the future.
