If you are a swimmer and used to tracking laps in the pool and heart rate, do not buy the fitbit sense 2. It only tracks time in the pool just like the clock in the pool room.
No matter how many complaints are made, Fitbit gives me a valid reason to make this the fastest purchase return.
It does not track laps in the pool and when you manually count them and check the app after your activity, you will not see the same number. I counted 100 laps manually and saw 92 afterwards,
Horrible purchase, I'll buy a $100 tracker that does this tracking.
