ExpidusOS is a desktop and mobile operating system from Midstall Software designed to unify the mobile and desktop experience.

1 minute


To create an open source operating system capable of running on mobile and desktop devices.


Traditionally, applications have to be redesigned to run on mobile and desktop devices. With ExpidusOS, it is possible to design a single version of the application to run on mobile and desktop devices. This has the benefit of saving time and resources for developers while also maintaining a coherent experience.


ExpidusOS is designed using Flutter, a cross-platform application framework made by Google. We have adapted Flutter to be able to run the GUI of ExpidusOS to create an interface which responds and feels faimilar between devices.
