Open-source operating system for smartwatches
Watch example

Hack your wrist

AsteroidOS is an open-source operating system for smartwatches.

Supported devices

Four types of smartwatches are already supported by AsteroidOS and more are yet to come. Check if your watch is compatible !

Freedom & Privacy

We believe that when it comes to wearable devices, users should have full control over their machines and data. AsteroidOS has been created from the ground-up with modularity and freedom in mind. For this reason, it is a free and open-source project.

Proven building blocks

AsteroidOS is built upon a rock-solid base system. Qt 5.6 and QML are used for fast and easy app development. OpenEmbedded provides a full GNU/Linux distribution and libhybris allows easy porting to most Android and Android Wear watches.


Since its creation in 2015, AsteroidOS has been led by Florent Revest, but is open towards external contribution and collaboration. The project is still in active development and if you want to help, make sure to check the Get Involved page.
