Pokémon Sleep, the app that aims to designate Pikachu as your certified sleep neurologist, is now available in the United States. The app was announced way back in 2019, suffered a four-year delay, and is now quietly rolling out all over the world. Earlier, Pokémon Sleep arrived in Canada. Sleep works by having you place your phone on your pillow after doing any of the fifty ‘leven million Pokémon-themed activities you can do nowadays. The app purports to track your sleeping habits via your phone, and when you wake up in the morning, the app will tell you how well you slept and compare your sleeping style to that of other ‘mon. According to The Pokémon Company, a little Pikachu is inside the ball and can sing you lullabies and act as your alarm in the morning. The device also works with Pokémon Go, allowing you to automatically spin pokéstops without taking out your phone. Pairing Pokémon Go Plus+ with either Pokémon Go or Pokémon Sleep will net you special rewards in each and retails for $55.
