I’m presently using the huawei watch fit 3 on gadgetbridge nightly, which I am enjoying but it definitely has its quirks.
They’re also adding the Garmin watches, which are well known for their activity tracking.
Not op, but I’d recommend looking in to keycloak.
Unsure why this is where the line is drawn, but okay.
Just out of curiosity, what kind of content do you come by that you’d like to save a full page copy of?
