For iOS, Geometry Dash World was released on December 21, 2016, and for Android, it was released on December 22, 2016. RobTop Games is responsible for the development and publication of this free expansion app for Geometry Dash, which is financed by advertisements. Additionally, it is divided into two worlds, each of which contains five levels, and it has ten unique short levels that must be performed in the correct order. The game is a scaled-down version of the full version of Geometry Dash, and it has been used as a preview for some new content that would be included in an upcoming update of the full version on two separate occasions: the first time was right before the release of Update 2.1, and the second time was right before an update that was released before Update 2.2. Although there are a limited number of accomplishments, icons, collectibles, stores, and vaults available, there are a variety of them. Through the usage of user accounts, it is also possible to move certain unlocks data across to the full version of the game. In addition, once all of the main levels have been finished, the user is granted access to the user level selections, which include the daily level, the weekly demon, and other featured levels.
