Pokémon GO is a free-to-play, location-based augmented reality game developed by Niantic for iOS and Android devices. The game was released in select countries in July 2016. In the game, players use a mobile device’s GPS capabilities to track, capture, battle, and train virtual creatures, called Pokémon, which appear as if they are in the player’s real-world location. The game supports in-app purchases for additional gameplay items.
