The game allows players to capture, battle, and train virtual Pokémon who appear throughout the real world. It makes use of GPS and the camera of compatible devices. Although the game is free-to-play, it supports in-app purchases of additional gameplay items. An optional companion Bluetoothwearable device, the Pokémon Go Plus, is planned for future release and will alert users when Pokémon are nearby.
The game received a mixed critical reception. However, it was the most downloaded smartphone app in the United States in its first three days of release and was a boon to Nintendo's stock value.
