Whoop 4.0 review: Screenless wearable helps you avoid injuries, track sleep details | ZDNet


The Whoop 4.0 is much more than a detailed sleep tracker, and people who work out regularly will see more benefits than those who lead a sedentary life. It's a great way to understand your body and optimize your workout regimen.

Very comfortable for 24/7 wear ; Detailed sleep tracking ; Informative coaching ; Unique battery pack system ; Affordable ; Useful clothing options

Battery life could be longer ; No support for importing GPS data

The New Whoop Wearable Is Smaller, Smarter, and Still Unnecessary


The upgraded wearable subtly tracks a whole bunch of metrics, but it leaves a lot to be desired.

Low-profile, waterproof, does a good job of monitoring your heart rate, and has the best charging solution of any wearable I’ve tested.

Whoop 4.0 review


The Whoop 4.0 is a serious fitness tracker for anyone who cares about tracking sleep and heart rate. Here's our Whoop 4.0 review.

Sleep tracking is better than most other trackers on the market ; Heart rate, skin temperature, SpO2 sensors ; Smaller than the Whoop 3.0 ; Interchangeable bands ; Compatible with Whoop Body

It does require a monthly subscription ; No screen ; No GPS

Like all items of fitness tech, the Whoop 4.0 is only worth it if you use it, but if you’re looking to enhance your training with in-depth data, or learn to work out more intuitively after a string of overtraining injuries, it’s one of the most...

Whoop 4.0 review: a diehard fitness tracker for people who like pushing their limits


The Whoop 4.0 is better, bolder and more capable than its predecessor but only people who work out often will benefit from using it

Comfortable enough to wear 24/7 ; Tracks heart rate and strain accurately ; Sleep tracking is excellent ; Health Monitor overview is useful and easy to understand

Doesn’t track basic stats (e.g. steps) ; Membership costs can stack up ; Still not the most precise when worn on the wrist

The Whoop 4.0 is the perfect fitness tracker in the sense that it actually tracks your fitness level instead of monitoring arbitrary health stats such as steps and water consumption. However, especially because of its hardcore nature, it might only be...
