I’ve been trying to take gym stuff more seriously lately and sometimes something like a fitbit seems like a great idea, are there any that don’t just harvest you for minimal utility on your end?
Sorry if this has be answered before but I think searching is still weird
I would check compatibility of Gadget-Bridge (open-source, no internet connection) and then use whatever gadget doesn’t require register. My amazfit bip (old version) is basic for gym (not that I need it…) but for hiking I can record the track heart-rate.
