Full Report
Pokémon Sleep has announced version 3.8.3, with the page dated October 8, 2026. The update includes an improvement and other bug fixes; players are instructed to update to the latest version through their app store.
The official listing names iOS and Android as platforms and describes the game as free to play with in-app purchases. It also describes Pokémon Sleep as a way to track and record sleep using a smart device.
For recent maintenance context, a separate October 5 notice reported a home-screen display issue affecting an event bonus, said game progress was unaffected, and stated that a fix was planned for a future update. That notice provides context about a separate issue; it does not establish that version 3.8.3 fixes it.
Why This Matters
The version number and app-store update instruction give players a practical way to identify and obtain this maintenance update. Because Pokémon Sleep is used to track and record sleep, keeping the app current matters to ongoing use; the earlier display-bug notice is context, not evidence that version 3.8.3 resolves that issue.
