I’d like to procure some fitness tracking devices for myself and my partner. Something like FitBit to track heart rate, sleep schedule, etc. Ideally, they do not require 3rd party data collection or services in any way. I’m open to manual steps and/or self-hosting software as needed.
Can anyone here recommend specific brands or devices?
There are some that do steps and heart rate, but not sleep. I have a banglejs v2 that’s pretty cool. It collects the data, but you’ll be responsible for gathering it.
