Rated 4 out of 5 stars
Works well and is comfortable
So far so good. The whoop provides some insightful data. It is comfortable to wear to the point where I forget its on. Changing is innovative and you dont neeed to take it off to charge. I would rate 5 stars but cant seem to figure out how to set a target heartbeat range say for exercising/cardio. It would be awesome if you could set the range and get alerts when you go over or under target while running or on the treadmill

Best
I’ve been wearing the Whoop 4.0 for over a half a year, the unobtrusive wrist strap never leaving my arm Whoop’s primary function is to quantify recovery efforts, mainly sleep, and balance them with strain. Through monitoring no less than six physiological markers during sleep and aligning them with personal logs and patterns of strain, an active person can dial in how actions, foods, and other things affect their sleep — and how that sleep affects training efforts.

Worth the investment!
Fits great, easy to set up. The metrics and tracking are really great if you are into training and getting the most out of yourself athletically. The battery is easy to charge and charges rather quickly giving you 3-4 days without having to take it off. The app that receives the information is great for tracking and setting performance and fitness goals, including the sleep tracker which has a journal feature that helps determine patterns and ways to get more sleep / performance. I'm 53, and wish I had this when I was younger but better late than never. A few pics and a detail of the sleep metrics provided. 33 years in the fire service doesn't lend itself to solid sleep but at least I have answers and something to work on based on the info.
