For the Petit Planet download, start from the game's official website and choose the platform route for your device. PC, iOS, and Android are scheduled for the December 4, 2026 public launch. As of November 2, a store listing or pre-registration button is not proof that the public game is already playable.
The Final Beta ended on October 19. Its invitation links and historical installation guides describe a closed test rather than the public release client.
Pre-download starts before playable access
Pre-download is listed for December 1, 2026, ahead of the December 4 public launch. Use that period to prepare the official files; completing installation early does not let you enter the public servers before launch. No precise pre-download or server-opening hour is established here.
Identify the correct listing
The game is called Petit Planet, with HoYoverse branding and COGNOSPHERE PTE. LTD. as the mobile publisher or seller. The Google Play package identifier is com.HoYoverse.Planet. The Apple app identifier is 6776621908.
Confirm the exact game title and publisher before choosing a download route.
These identifiers help distinguish the game from unrelated apps and similarly named cozy games. In particular, Petit Island is a separate product.
Platform routes
| Device | Official route to follow | What to check |
|---|---|---|
| Windows PC | The official site's PC route or the Petit Planet Epic Games Store listing | Release status, client instructions, and current system requirements. |
| iPhone or iPad | The official Petit Planet App Store listing | Device compatibility, region, and whether the action is a reservation or installation. |
| Android | The official Petit Planet Google Play listing | Publisher, compatible device, and the current store action. |
A store page is useful for identifying the product before release, but the action shown on your account matters. Pre-registration, pre-order, installation, and entering the game are different stages.
iPhone and iPad preparation
The current Apple listing requires iOS or iPadOS 15.0 or later. Its listed size is 3.7 GB. That is the store's displayed package size, not a promise of the final installed footprint after updates and game data downloads.
The listed public release date is December 4, 2026. Follow the compatibility information shown for your own device rather than assuming an older test's iOS requirement still applies.
Android preparation
Use the Google Play listing with the correct publisher and package identifier. The captured listing includes in-app purchases and random-item purchase disclosures. “Free download” therefore refers to obtaining the game, not a guarantee that every optional item is free.
No final Android download size or universal device compatibility is established here. Check what Google Play shows for the account, country, and phone you intend to use.
PC preparation
The Epic Games Store has a Petit Planet product listing. Use the official route to confirm which client and installation instructions apply at release. A Steam news story about the game is not a Steam app listing, and a generic “PC” label does not prove a macOS version.
Historical Final Beta recommendations named Windows hardware, but those test specifications should not be relabeled as final public minimum requirements.
The latest published beta device recommendations
The Final Beta FAQ published the following recommendations. They are useful historical reference points for device preparation, not final public-launch minimum requirements.
| Beta platform | Published recommendation | Available storage |
|---|---|---|
| Windows PC | Windows 10+; Intel i 5 11th Gen or AMD Ryzen 5 5000 series+; GeForce RTX 2060 or Radeon RX 5600 XT+; 16 GB RAM+ | 18 GB |
| Android | Android 9.0+; Snapdragon 855, Dimensity 1000, or Kirin 990+; 6 GB RAM+ | 12 GB |
For iPhone and iPad, prioritize the newer App Store compatibility requirement of iOS or iPadOS 15.0+. Its displayed 3.7 GB package size and the test FAQ's available-storage recommendation measure different things.
PC and mobile can play across platforms
Cross-platform play is announced for PC, iOS, and Android. This identifies the launch versions that can play together; it does not confirm Steam distribution, a Mac client, or how purchases and progression will transfer to the later Switch 2 version.
Old beta download instructions
An old guide may explain how selected testers received an invitation email, checked access, and installed a test package. Those steps were tied to a particular test period and eligible account. They do not reopen the Final Beta now that it has ended.
For public launch, follow the current platform route. There is no verified need here to obtain a sold beta account, reuse an old invitation, or install a reposted APK to participate in the announced release.
