Universal OS

Universal OS, developed by Fall Inc, is a proprietary operating system that is designed to run seamlessly on various devices such as desktop computers, smartphones, tablet computers, smartwatches, smart TVs, IoT devices, and automobiles. The entire operating system is composed of a hybrid kernel and various layers called Packages, and they are designed for specific devices. Each device variant will have different packages installed. For example, a smartphone will have the phone package installed. As a result, Fall can develop operating systems for different devices without changing many codes.

Universal OS was announced at the Fall International Developer Festival on May 20, 2013, with its first developer preview released just a day after. The first public version of Universal OS was released on October 14, 2014. The latest major release of the operating system, Universal OS 4.0, was released to the public on December 17, 2020. Currently, all of Fall's consumer electronic products run Universal OS.
