“The Pokémon GO Plus is a small device that lets you enjoy Pokémon GO while you’re on the move and not looking at your smartphone. Pokémon GO Plus connects to your smart device over Bluetooth low energy (LE), allowing you to keep your phone in your pocket and go about your day-to-day activities. With Pokémon GO Plus, you’ll be able to play and enjoy your walk, run, hike, park trips, or visits to the library without having to look at your smartphone’s screen.”
How does it work? Simple, when you walk by a PokeStop, it’ll light up and vibrate to let you know. All you have to do is push the button in the center of the device and you’ll collect items from the PokeStop. When there’s a wild Pokemon nearby the Pokemon Go Plus will buzz. Tap the button and an attempt will be made to catch the Pokemon. However you won’t know if it worked unless you check the app to see if you capture attempt was successful. Happy hunting!
