AsteroidOS 2.0 Linux-based, open-source smartwatch operating system has just been released with features such as always-on display support, Tilt-to-Wake, a customizable QuickPanel, multiple launcher styles, Nightstand mode, performance improvements, and support for about 30 devices.
It’s been a long journey. We first noted the open-source project in 2016 when Florent Revest showcased a basic user experience on the LG G Watch, just before giving a talk at FOSDEM 2016 introducing AsteroidOS. This was followed by the launch of the Connect Watch (crowdfunded) AsteroidOS smartwatch in 2017 by a French company (which didn’t get funded), and AsteroidOS 1.0 was released in 2018. So it’s been ten years since it all started, and the developers have now released AsteroidOS 2.0.
AsteroidOS 2.0 highlights:
- New features
- Always-on Display, Tilt-to-wake, Palm-to-sleep
- Heart rate monitor app
- Initial step counting support
- Music volume control
- Compass support
- Support for Bluetooth HID and Audio
- Design, Usability, and App Improvements
- New QuickPanel with more settings toggles, app shortcuts
- Seven new app launchers
- Enhanced Wallpaper and Watchface gallery, along with new wallpapers
- Nightstand mode to use your watch as a bedside clock or simply show charging much more clearly.
- New background animation for more organic feeling of “breathing”.
- Diamonds – A 2048-like game
- Weather app design overhaul with different fonts (e.g. Noto Sans system font), improved legibility, and presentation of very long place names.
- Timer app redesign – Round watches optimization, background execution support.
- Flashlight app
- Animated Bootsplash logo
- Round screens with a flat tyre shape are now supported.
- Calculator app with new layout
- Improved button layout for easier operation and better legibility, especially on round displays.
- More translations – 49 languages in total, and 20 languages added since the last release.
- Etc…
- Performance and System Enhancements
- Optimized rendering resulting in smoother animations and transitions.
- Battery Life Improvements to extend battery life during daily use.
- Stability Fixes
AsteroidOS works with several synchronization clients, notably the AsteroidOS Sync Android app, the Gadgetbridge project (Android), a popular solution that works with a range of commercial smartwatches as well, the Amazfish client for SailfishOS and Linux Desktop, and Telescope for UBports Ubuntu Touch.
AsteroidOS 1.0 supported the following devices:
- LG G Watch, LG G Watch Urbane, LG G Watch R
- Asus Zenwatch 1, Asus Zenwatch 2, Asus Zenwatch 3
- Sony Smartwatch 3
- Software emulator for testing and development
AsteroidOS 2.0 adds more:
- Fossil Gen 4, 5, 6 watches
- Huawei Watch and Watch 2
- LG Watch W7
- Moto 360 2015
- MTK6580 (harmony/inharmony) – I assume a range of devices based on MT6580
- OPPO Watch
- Polar M600
- Ticwatch C2+ & C2, Ticwatch E & S, Ticwatch E2 & S2, TicwatchPro, Pro 2020 and LTE, and Ticwatch Pro 3
Experimental/partial support was also added for Casio WSD-F10/F20 (note: some users have bricked their watch), LG Watch Urbane 2, Moto 360 1st gen, Samsung Gear 2, and Samsung Gear Live. Many of the watches are older models, but that’s fitting for the project since environmental responsibility leading to reduced electronic waste is one of the goals of the project, along with privacy and education.
You can check out some of the user-facing changes and UI performance in AsteroidOS 2.0 in the 7-minute video below, featuring various Ticwatch, OPPO, Casio, Fossil, LG, and Huawei smartwatches.
You’ll find more details on the project’s GitHub account, the announcement, and the official website. Timo Könnecke (moWerk), AsteroidOS team contributor and maintainer, contacted us about the release and also mentioned that they are always looking for hardware porters for new watches or bug fixes on existing ones (C programming), app & watchface developers familiar with QML/Qt and JavaScript, as well as translators, testers, designers, and documentation writers.

FTFY 🙂
Nice, but can’t realy find any cheap or availible supported watches, does this work on some cheap ali stuff?
I have gotten 4 watches to try for around 15-20 each on ebay and a new battery is like 15$ so not bad overall.
Doable, can u please share wich types? and wich work best
All this and still not a single Pixel Watch is supported, only 10+ year old watches that are going to have totally cooked batteries. I understand the 1st gen model requires a special debug adapter, but models moving forward can do adb and fastboot via their charging cradles.
Sorry Ryan,, but I want to debunk part of your comment. The Fossil Gen 6 is a watch from 2021. So not a 10+ year watch. I know it’s not in the same league as the Pixel Watches, but I think having 30 supported devices is quite an achievement already, seen that it’s quite niche development area in my opinion. As the article already states, they are requesting more volunteers (contributers) in any way, so they are limited in manpower.
I agree in part, the pixel watches should have been a target.
Really waiting for rinato support in pmbootstrap!
Still no Galaxy watches at all 😞
