Nintendo and The Pokemon Company have announced Pokemon Sleep.

Developed by Select Button, the new app will “turn sleep into entertainment” much like how Pokemon Go made walking more entertaining- in the company’s own words.

Using the Pokemon Go Plus+, the device will use accelerators to detect how much sleep you get, when you wake up and go to bed. These all contribute towards some form of unspecified gameplay where you will be “excited to wake up” and see the results. We will keep you informed as we learn more.

The game will be developed alongside Select Button, the developer previously involved with Magikarp Jump on smartphones. Niantic also stated they will be working on “turning sleep into gameplay”. In other news, Snorlax with the move Yawn will appear more commonly in Pokemon Go for a short time.

Pokemon Sleep will launch in 2020. You can find the full run-down below:

Soon, Trainers will be able to wake up with Pokémon every morning with Pokémon Sleep, a mobile app from The Pokémon Company. Pokémon Sleep aims to turn sleeping into entertainment by having a player’s time spent sleeping, and the time they wake up, effect the gameplay. While more details about the app’s functionality will be revealed at a later date, it was announced that a new device from Nintendo, Pokémon GO Plus +, will connect to Pokémon Sleep and launch with the app. The device will use an embedded accelerometer to track a user’s time sleeping and send this information to their smartphone via Bluetooth. This new device also has the same functions as the original Pokémon GO Plus, so Trainers can use it with Pokémon GO during the day and with Pokémon Sleep at night. Trainers can look forward to Pokémon Sleep launching for mobile devices in 2020. To celebrate this early look at Pokémon Sleep, Trainers around the world will have the chance to encounter Snorlax that are lying down and deep in sleep in Pokémon GO beginning today.
