Nintendo confirmed this morning that their new pokémon mobile application will be titled Pokémon Go. This app will allow users to catch creatures while on the go. You can upgrade and progress your trainer, battle rival monsters, and participate in challenges.
The Pokémon Plus is a device that allows you to play Pokémon Go without having to look at your phone. The device, meant to be worn as a watch, will light up when you're near a pokémon. A button on the front will let you attempt to catch the creature, and corresponding LEDs will let you know whether or not it was caught. Pokémon Go can be played without the Pokémon Plus, but it certainly enhances the experience.
Pokémon Go and Pokémon Plus will be available July 2016 for Android and iOS.
