Sleep Features

Data Precision

The Ultrahuman Ring Air excels in accurate sleep tracking with its advanced sensors that provide precise measurements of sleep stages (e.g., light, deep, and REM) and HRV.

The Apple Watch Series 9 also has accurate sleep tracking, but its primary focus is on providing a complete view of your health. It tracks sleep stages, heart rate, and even skin temperature.

Health Metrics

Both devices track various health metrics, but the Apple Watch Series 9 goes a step further by offering additional features such as blood oxygen level monitoring and ECG readings.

To measure your blood oxygen levels with your Apple Watch, open the Blood Oxygen app. Place your arm on a flat surface, ensuring your wrist is flat and the watch display faces up. Tap "Start" and keep your arm still for the 15-second countdown. Once the countdown is complete, your blood oxygen results will appear on the screen.

Heart Rate Monitoring

Heart rate monitoring is a key feature for both devices. The Ultrahuman Ring Air continuously monitors your heart rate throughout the night using red, green, and infrared LEDs.

The Apple Watch Series 9 also offers continuous heart rate monitoring, but it goes beyond just sleep tracking. It provides real-time heart rate data during workouts and daily activities.

User Experience

Comfort and Design

The Ultrahuman Ring Air is incredibly lightweight, weighing just 2.4 grams. It fits comfortably on your finger without causing any discomfort during the night.

Fingers provide more accurate biomarker readings than wrists because they have higher blood flow and a greater density of arterioles.

Because it is so light, you can easily forget that you're wearing it—ideal for sleep tracking. The ring is also hypoallergenic and features a smooth inner lining for maximum comfort.

Weighing about 31.9g to 38.7g, the Apple Watch Series 9 is not as lightweight as the Ultrahuman Ring Air but still has a user-friendly interface with a touchscreen display. This display allows you to review various features and access your sleep data with just a few taps.

Usability

The Ultrahuman Ring Air is straightforward to use, with a companion app that provides detailed insights into your sleep data. The app is intuitive and easy to navigate and it’s easy to track your sleep patterns and make adjustments.

The Apple Watch Series 9 also has a user-friendly experience, with its touchscreen display and integrated health app. The watch provides real-time notifications and insights, so you can stay on top of your sleep and overall health.
