App duplicator tool
Multi App: Dual Space is a free utility application for mobile from developer waxmoon. It's an app duplicator that lets users run two instances of their favorite apps and games at the same time. It comes with a simple and intuitive user interface and a fuss-free setup process for beginners.
Dual apps
The Multi App: Dual Space application works in one of two ways, with the first letting you run two instances of the same app or game, which will essentially let you have multiple accounts running simultaneously. It supports various popular messaging services, social media platforms, and online multiplayer games available today.
The other method is to create dual spaces that will help you separate personal and work applications for easier management. To support this, notifications will come independently and no data overlap will occur. On a side note, recent updates to the app have rendered it unusable. It fails to open anything and often crashes.
Handy but has a major caveat
Multi App: Dual Space allows users to have dual apps running on their devices, and it works pretty well with wide app support and a simple setup process. However, it has been suffering from a persistent issue with no fix to speak of. Until it gets addressed, you're better off trying something else.
