Pokémon Sleep

Pokémon Sleep is based around tracking the sleep of the player, and earning rewards for sleeping longer. The game uses the microphone and accelerometer of the player's phone to track sleep. Players can optionally use the Pokémon Go Plus+ to play sounds to remind the player of their bedtime, as well as to track sleep without needing a phone on. In September 2024 smartwatches were added as a sleep tracking method.

Players are given a Snorlax by Professor Neroli to observe its sleeping patterns when they start playing for the first time. The player can give Snorlax berries and meals throughout the day. The more Snorlax is fed, the higher its power, and the more types of Pokémon it can attract. After reaching certain milestones with Snorlax's score, its rank will increase, allowing rarer visiting Pokémon after sleep.

Pokémon Sleep is developed by Japanese studio Select Button, and published by The Pokémon Company. It was announced on May 28, 2019, by Tsunekazu Ishihara, CEO of the Pokémon Company, during a press conference held in Tokyo as well as on the company's official Twitter page. The app was set to be released in 2020, but did not appear, leading to speculation that it was cancelled. However, on 5 April 2021, a fan reported on Twitter that a SSL certificate had been registered for dev-eotxawxn.sleep.pokemon.co.jp.

A Pokémon Go APK data mine in January 2022 revealed several additions to the Pokémon Go app to integrate with Pokémon Sleep, including connecting to the Pokémon Go Plus + accessory, reviewing sleep patterns, and earning in-app rewards. These were confirmed by the Pokémon Day 2023 Pokémon Presents, in which they officially announced the Pokémon Go Plus + (Plus Plus) Accessory.

Upon the app's second anniversary in July 2025, it was announced that it had been downloaded over 28 million times and had recorded over one billion sleep sessions. In April 2026, the developers announced that the game has reached 30 million downloads.
