depends what you want to track/achieve ☺️
> apple watch
pro: great alrounder with good data quality and graphs
con: push notifications, „smart“ etc.
> polar beats band
pro: measures through ECG so is by far the highest accuracy during workouts. integrates with apple health
con: app sucks
> oura ring
pro: best sleep tracker on the market
con: ring is in the way during workouts and scratches up. fitness tracking is not super accurate.
> whoop (no personal experience)
pro: seems to be a good alrounder if you dont like the apple watch. can be worn during workouts. great analytics
con: sleep tracking is a little inferior to oura (according to benchmark studies)
my setup:
- wear oura 24/7 for 3-4 years now excpet when i
- switch for polar beats during workouts
—> i get to see amazing long-term effects in HRV, resting heart rate, sleep etc. with oura and super precise tracking of max heart rate and zones with polar beats
hope this helps ☺️
