My VivoActive 4 tracks this without any external accessories. I've never really looked at the data and can't tell you how accurate it is though.

- lukeschlather 6y agoI have spent some time testing it, it is useless. Maybe it's accurate if you're not doing controlled breathing. I haven't had someone else watch me and compare. (I am also a trained vocalist and do a fair amount of yoga, it might be that it's only accurate for people with minimal breath training, or people with more exercise-focused breath training.)
