Not sure if this counts, but someone I know made a javascript interpreter that runs on ESP32, ported it to a smartwatch and wrote a whole open source operating system. He put it on Kickstarter and reached the goal. He now sells the result, and a second one for a different smartwatch: https://www.espruino.com/Bangle.js2

There's an app store here: https://banglejs.com/apps/, but all apps are free and open source in a single github repo.

This is cool. So "175mAh battery, 4 weeks standby time" what is the battery time during normal use? Not just sitting on a shelf. Use all day at work, sleep tracking during the night, etc.

I can only recommend Espruino and the BangleJs, great work.
