Pokémon Go ( stylized as Pokémon GO ) is a free-to-play location-based augmented reality[note 3] mobile game developed by Niantic for iOS and Android devices. It was released in most regions of the world in July 2016. Making use of GPS and the camera of compatible devices, the game allows players to capture, battle, and train virtual creatures, called Pokémon , who appear on device screens as though in the real world. The game is free-to-play, although it supports in-app purchases of additional gameplay items. An optional companion
Bluetooth wearable device , the Pokémon Go Plus, is planned for future release and will alert users when Pokémon are nearby.
