my 6th fitbit in 10 years just broke.
Now that they have been acquired by google I want to take the opportunity to migrate to a freedom respecting, open source alternative option for a fitness tracker (not a smart watch if possible).

requirements:
-must track heart rate
-must track steps
-must auto-detect excercise
-must be open source and freedom respecting or making that its goal.

any tips are appreciated
