The phrase denotes the use of a third-party application, initially named TutuApp, on Android devices to access a modified version of the popular augmented reality game, Pokmon Go. This unofficial method allows users to potentially circumvent certain game mechanics or geographic restrictions imposed by the original application.
The appeal of such methods stems from desires to expedite game progress, access rare in-game elements more easily, or participate even when geographical limitations exist. Historically, these approaches have been used to modify various games to offer alternative experiences or bypass intended gameplay restrictions, but the use of third-party applications to modify gameplay frequently comes with inherent risks to personal data security and potential account termination from the original game developer.
