Whoop 4.0 Summary

Before diving deeper into this Whoop 4.0 Review, here’s a quick summary of its specs and features:

Whoop 4.0 Review: Features and Functionalities

Whoop 4.0 is a fitness tracker known for its various overall health monitoring capabilities, including tracking sleep, activities, strain, stress, and recovery. Let’s break down all of them one by one.

Fitness Tracking

Monitoring activities is one of the many things that make Whoop 4.0 stand out in the sea of fitness trackers. As a fitness tracker, you can expect nothing less from the wearable. Whoop 4.0, in fact, returns pretty accurate data, closely mirroring the data my Oura Ring and Apple Watch SE 2 collected. With its adjustable band design, you can wear it on your arms, arms, or even ankles—wherever is more comfortable for you during activities.

Of course, Whoop 4.0 is not a complete fitness tracker without automatic activity detection. Its automatic activity detection can automatically track over 60 activities, including strength training, powerlifting, HIIT, yoga, pilates, triathlon, skateboarding, and diving. Whoop takes the cue from periods of continuous elevated heart rate (15 minutes) and higher-than-average movements (or what it calls Strain) to detect these activities as well as the time when you are active or working out.

Sleep Monitoring

Whoop 4.0 records all the basic sleep metrics, including sleep stages (deep, REM, light, and awake), sleep duration, sleep/wake-up time, and resting heart rate. It will come up with a sleep score based on these and other factors like recent strain and sleep debt.

There are two important things you need to remember about its sleep monitoring. Firstly, it only logs sleep longer than 1 hour and classifies it as sleep or a nap accordingly based on the time it occurs. When you have a shifting sleep schedule, this could become a big concern for you like it is for me. Secondly, the one thing that makes me think twice about using Whoop 4.0 for sleep monitoring is its band design, which can be a tad bit uncomfortable and restricting.

Strain, Recovery, and Stress Monitoring

If there’s one thing that has always stood out with Whoop 4.0 is strain monitoring. In an effort to look at fitness in a holistic manner, Whoop takes strain and recovery into consideration.

Whoop 4.0 looks into ambient temperature to sense body temperature, which is a primary factor when the body is under strain or stress. Truth be told, ambient temperature can get too far off from the actual body temperature, thereby affecting your strain, recovery, and stress scores. This is where electrodermal activity (EDA) comes in, helping you get a more accurate read on your strain, recovery, and stress.

While strain and stress monitoring is highly dependent on workouts, work, errands, and other activities, recovery looks at your heart rate variability (HRV) and sleep quality more than anything else.

Whoop 4.0 Review: Specs and Design

Whoop 4.0 has four times the number of photodiodes on the sensor and five LEDs that use green, red, and infrared light for gathering various data points. It’s certified to IP68 standards, so it’s waterproof up to 10 meters. And its battery can last up to 5 days.

In terms of design, Whoop 4.0 is pretty much like any fitness tracker except it does not have a display. For people who want to focus on their workouts and sleep, this is quite a nifty feature. Whoop is lightweight to carry too.

The band design—which comes in more than 20 different styles—allows you to wear it on your wrist, forearm, upper arm, or even ankle. If you are using gloves at the gym like me, this versatility is a life-saver.
