From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

AsteroidOS 2.0 is here with a massive load of new features and support for many more watches.
Thank you to all contributors who made it possible!

Enjoy the wrist-sized Linux ride!
I would think Linux would be way too heavy for these watches. A lot of them use pretty lean MCUs, a far cry from the beefy Qualcomm phone chips that Post market runs on.
Even running zephyr on the NRF52840 can get heavy with adding a bunch of apps to it.
AsteroidOS mostly supports watches that come stock with Wear OS, which is a modified version of Android, which, guess what, runs a Linux kernel. These watches are on the more powerful end of the computing spectrum. As you say, there are a lot of smart watches that use pretty lean MCUs, but those aren't running AsteroidOS or Wear OS, as noted in this FAQ entry.
Nah, it's not "too heavy" the linux kernel is running on all kinds of tiny processors.
My limited understanding is, that usually the problem is a lack of support and assistance from the hardware manufacturer to optimise the OS for their hardware.
This is why GrapheneOS and similar have poorer performance on phones et cetera.
Generally correct, but,
FWIW my gOS gets 40-50% more battery, likely due to lack of parasitic (see what I did there?) google services.
I mean, look at the specs of a smart TV or smart fridge. The specs on them are shit and they run Linux.
Hell there are whole distros designed to run on minimal as fuck hardware.
I would assume it's highly stripped down similar to what Google does to android with watchos ?
