I pay for a WHOOP 5.0 with my HSA so nothing really comes out of my bank account.
Pros:
2 week battery, comes with an external charging puck you just slip on for an hour, don't have to take it off
Good sleep tracking and heartrate data
The biggest thing is it measures your "Strain" for the day and tells you how much your body can take for the day.
Auto-notices strenuous activity
Light, easy to forget it's there.
Built-In A.I. on the app is useful for tracking your trends and getting insights on behaviors. Of all things that negatively affect recovery, eating past 8PM is the worst thing for me.
Because of the battery and easy to forget it's there, it's easy to get all your sleep tracking
Doesn't have a screen to scratch
Doesn't have a screen to crack
Wear your regular watch without looking weird for wearing two watches as you would if you had a smartwatch.
Cons:
$240/year subscription. Personally negated by utilizing an HSA
The most expensive $350/year or whatever "perks" are actual bogus, just get the middle plan.
People who went from WHOOP 4.0 to WHOOP 5.0 got shafted if they bought extra bands because they weren't compatible and the jump from 4.0 to 5.0's is worth it, but if they want extra bands its' just more money. Sucks to be them.
