alt Hacker NewsI have garmin as it doesn't require any sort of connection or activation to function out-of-the-box.
Just put it on your wrist.
You CAN decide to use garmin-connect for apps/updates or pair it with your phone, but I never have and I'm fine.
Apple watch and others require activation.
You can plug in a Garmin to a computer with a cable and pull the files off the watch, as it acts like a USB drive. No app required.
