  • AsteroidOS is an Open Source OS for Smartwatches
    Florent Revest is a French computer science student who has been working on an open source operating system for smartwatches for the last two years. Yesterday, he officially launched version 1 of the alpha for AsteroidOS. The goal for the platform was to create something that gave smartwatch owners more control over their privacy, as well as the hardware they purchased. Florent feels that the current proprietary platforms do not guarantee this, and this was the basis for AsteroidOS. He wanted his open source smartwatch operating system to provide freedom with free software, more privacy than other wearable platforms offer, interoperability so it could communicate with other devices, modularity that enabled the user to tweak and change the OS as they see fit, the ability to port the software to as many devices as possible, and gathering a community who is passionate about the platform.

    Smartwatches may not have taken off like companies were hoping, but they have come quite far in terms of what they can offer and what sorts of features are available for the many different models of smartwatches that are out there. Even with the updated functionality of options like Samsung’s Gear S lineup and Android Wear platforms, though, smartwatches can still feel a little bit limiting, and part of this undoubtedly includes the reason that the operating systems aren’t as open as platforms like Android. That is now changing thanks to a platform called AsteroidOS which is an open source operating system for smartwatches.
