It’s been 8 years… since we last covered AsteroidOS on It’s FOSS. The promising project kind of stalled, or so I thought, until the recent announcement of AsteroidOS version 2.0 release. I am happy to see the project progress.
What is AsteroidOS?
AsteroidOS is a free, open-source operating system designed specifically for smartwatches. It is a Linux-based OS built as an alternative to proprietary smartwatch platforms like Wear OS (Google) or watchOS (Apple). It’s completely community-driven and focuses on user freedom and privacy.

The project is built around three core principles:
- Privacy first: No telemetry, no forced cloud services, full user control over data.
- Environmental responsibility: Extending the life of existing smartwatches long after manufacturers drop support.
- Education & contribution: Helping every interested user become a contributor. With code in QML/Qt, JavaScript, or C, users can modify the OS to suit their preference and need.
What’s new in AsteroidOS 2.0?
The main new features are Always-on Display (the screen stays visible at all times), Tilt-to-wake (raise your wrist to wake the screen), and Palm-to-sleep (cover the screen to turn it off). These features give AsteroidOS a modern smartwatch experience.
Other than that, here are some other features worth looking at.
New sensors & apps
A dedicated heart rate monitor app and initial step counting support have been added, along with a compass app and Bluetooth HID and Audio support. There’s also a new Flashlight app and a game called Diamonds (a twist on the 2048 concept).
Design & usability overhaul
The old QuickSettings menu has been replaced by a fully redesigned, highly customizable QuickPanel with more toggles, app shortcuts, and a power-off timer. Seven new app launcher styles have been added, selectable from a new…
