Pokémon Go (stylized as Pokémon GO) is a 2016 augmented reality (AR) mobile game, part of the Pokémon franchise, developed and published by Niantic in collaboration with Nintendo and The Pokémon Company for iOS and Android devices. It uses mobile devices with GPS to locate, capture, train, and battle virtual Pokémon, which appear as if they are in the player's real-world location. The game is free-to-play; it uses a freemium business model combined with local advertising and supports online purchases for additional in-game items as well as virtual and real-world events.
