Feature Comparison

The Whoop 4.0 is a screen-less wristband that can be worn on your wrist, forearm, or bicep. Its adjustable band ensures a snug fit for various wrist sizes. While both devices are designed for comfort, your preference for a ring or wristband will play a significant role in your choice.

The Whoop 4.0 doesn’t have a screen; just a powerful sensor.

Tracking Capabilities

Both devices offer comprehensive tracking capabilities, but they approach sleep tracking differently.

Sleep Stages

The Ultrahuman Ring Air tracks different sleep stages, including light, deep, and REM sleep. This information helps you understand how much time you spend in each stage and how it affects your overall sleep quality.

Whoop 4.0, on the other hand, provides a sleep score based on your total sleep duration, sleep efficiency, and disturbances. It tracks your sleep stages to give insights into how well you recovered overnight.

Heart Rate Variability (HRV)

Heart Rate Variability (HRV) is a crucial metric for understanding your body's readiness and stress levels. Both devices track HRV 24/7. The Ultrahuman Ring Air calculates HRV based on your sleep data and provides insights into your recovery. Whoop 4.0 tracks HRV and heart rate as part of the Stress Monitor.

Stress Monitoring

Besides sleep tracking, both devices offer stress monitoring features. The Ultrahuman Ring Air tracks your stress levels through heart rate and skin temperature data. Whoop 4.0 provides a real-time Stress Score and offers science-backed breathwork techniques to help you manage stress.

Whoop 4.0’s Stress Monitor tracks your heart rate and HRV in real time to assess your physiological stress response. It compares this data to a 14-day baseline to provide a Stress Score between 0 and 3, accounting for any movement to differentiate exercise from other stressors.

Battery Life

The Ultrahuman Ring Air has a battery life of up to 6 days, so you don't need to charge it frequently. Whoop 4.0 also provides a battery life of around 4 to 5 days. You can also purchase an optional portable charger that can be attached to the wristband while you wear it.

User Insights and Recommendations

The Ultrahuman Ring Air provides a recovery score each morning, based on your sleep, heart rate variability, and activity data. It’s a percentage that measures from 0 to 100 - a score of 85 or above indicates better recovery. This score helps you understand how well your body has recovered overnight. The ring also tracks your breathing rate and blood oxygen levels, offering a holistic view of your health.

Whoop 4.0 compiles a daily recovery score based on your sleep, HRV, and resting heart rate (RHR). This score is expressed as a percentage and is color-coded to indicate recovery status. For example, a green (67-99%) score indicates that you are well-recovered and ready to perform. You’ll also get personalized recommendations to help you optimize your training and recovery, such as suggesting rest days or lighter workouts when your recovery score is low.

User Experience

App Interface

The Ultrahuman Ring Air app is intuitive and provides clear insights into your sleep and health data. However, some users find its data presentation slightly less intuitive compared to other apps.
