If you dislike both Apple and Google, then I wonder, with your skills, why you didn't consider using and improving PineTime with a GNU/Linux phone (Pinephone or Librem 5).
I have contributed to both Wasp OS (Colmi P8) & Asteroid OS albeit with just bug reports; Pinephone/Librem arent available in my country and since my goal is health with this project,the sensors in these devices are not accurate enough yet.
just curious: What's your view on Asteroid OS and its evolution, is it growing as a usable alternative for Android Wear OS?
I have it on my radar since v1.0, and whenever I see the two older Android Wear devices in my drawer I keep thinking that I should put them to some new use (i.e. make them control home devices directly or similar).
AsteroidOS by itself impressed me with its fluidity & UX, at time when wearOS was pure garbage. But I faced connectivity issues with the companion app; both in android and in Linux phones.
Now that Gadgetbridge supports AsteroidOS, I would like to give it a try again but my device require a battery change and it's been hard to find one. That brings the major issue with AsteroidOS - very limited compatibility for newer devices.
It's obviously true, although I don't believe that investing in a proprietary platform, which move toward more closeness, is a good decision in the long term.
