I’ve already looked into gadgetbridge, but all supported devices unfortunately have fairly limited functionality. I get that it’s the premise with the reverse engineering they do to make things almost work.

The bangle.js models are a fucking ugly apple watch clone, I’d never wear that thing. And I’m not looking to get an actual smartwatch, I have no need for any of that clutter or a desire to charge my watch daily or every other day.

I’ve used a coros pace 2 for a long time, definitely not private but very limited smartwatch bullshit and >week of battery with +1h of daily GPS tracked running. Not supported by gadgetbridge though.
