Ultrahuman vs. Whoop Review: Features and Functionalities
Sleep Monitoring
Both wearables have an impressive sleep tracking functionality, monitoring metrics like sleep stages (light, REM, and deep sleep), sleep duration, resting heart rate, and blood oxygen. Based on these and a few other factors, Whoop and Ultrahuman can come up with sleep scores to evaluate how good your sleep is.
Whoop 4.0 also takes recent strain and sleep debt into account when calculating the sleep score, so you get a holistic view of your sleep habits. In addition, Whoop only logs sleep longer than 1 hour. Anything less than that is considered a nap, depending on the time of day it occurs.
Ultrahuman Ring Air looks at your circadian rhythm diet and meal timing as a major factor for your sleep and strain, so it’s not just physical exercise and light exposure they are considering.

Activity Tracking
When it comes to monitoring different activities and workouts, Ultrahuman Ring Air and Whoop 4.0 have a robust fitness tracking mechanism.
Ultrahuman Ring Air uses a 6-axis accelerometer to track metrics like steps, duration, active hours, and calorie burn. Its movement index is designed to keep users moving to maximize glucose metabolism. If you use the MyFitnessPal app like me, Ultrahuman supports it along with several others.
Meanwhile, Whoop 4.0 can automatically track over 60 activities, including strength training, powerlifting, HIIT, yoga, triathlon, and diving. But one thing about Whoop 4.0 that makes it a better fitness tracker is its versatile band design, which you can use on your wrist, arms, or even ankle. With Ultrhuman Ring Air, it’s difficult to bring it to the gym and lift heavy weights as you can really feel the metal pressing against your skin.

Heart Rate Monitoring
Another significant health metric is heart rate tracking. Heart rates are the core metrics used for monitoring sleep, recovery, activity, and stress and strain in the case of Whoop. Both devices have PPG sensors that track resting heart rate (used during sleep), heart rate variability (used for recovery monitoring), and active/live/workout heart rate (used during workouts).
Aside from these health metrics, Ultrahuman Ring Air and Whoop 4.0 can also track recovery, monitoring, blood oxygen saturation (Sp02), and period prediction capabilities. Both Ultrahuman Ring Air and Whoop 4.0 also use a temperature sensor to track body temperature, which is used for recovery monitoring, sleep tracking, and period prediction.

The Outliers
One thing that makes Whoop 4.0 a standout in the wearable tech market is its strain monitoring capabilities, giving users a deeper look into their activities and how their body is impacted. Whoop’s strain monitoring is based on both cardiovascular and muscular exertion, which is monitored based on the person’s heart rate, movements as well as weights, reps, and sets used. If you are a fitness enthusiast, this aspect comes in very handy.
On the other hand, Ultrahuman Ring Air has a continuous glucose monitoring capability for keeping tabs on your blood sugar. No other wearable on the market has a blood sugar monitoring feature. If you are a diabetic or come from a family of one, this is a nifty functionality.
Do note that Ultrahuman Ring Air does not have a dedicated feature for stress management unlike Whoop 4.0.
