## Long description

The Amazfit Ultrahuman AIR Smart Ring Bionic Gold (size 9) is a compact biometric ring designed for continuous sleep and activity monitoring. Worn on the finger, it measures physiological signals to deliver insights into sleep stages, recovery and daily activity patterns. The device is intended for users who prefer a minimal, finger-worn tracker that combines a lightweight metal finish with sensor-driven health analytics.
Advantages
The smart ring provides fingertip-based biometric readings that can be more precise than wrist-worn devices for certain signals, benefiting sleep and recovery analysis. Its very light construction and hypoallergenic inner surface make it comfortable for prolonged wear, including overnight. Integrated sensors track heart rate, activity metrics and sleep quality while Bluetooth LE connectivity allows data synchronisation with a companion app.
Suitable for
Users who want continuous sleep staging and daily recovery insights
People who prefer a discreet, finger-worn tracker instead of a wrist device
Individuals tracking heart rate trends, active minutes, steps and calories
Those seeking lightweight wearable for 24/7 monitoring and sleep analysis
When it may not be suitable
The ring may not be suitable for users who need on-device displays, standalone GPS tracking, or advanced smartwatch features such as calls and apps. It also may not fit users who require frequent manual interaction with a device during workouts, since control and extended configuration are handled mainly through the paired mobile application.
Key specifications
Form factor: finger-worn smart ring in gold finish
Sensors: optical heart rate sensor and motion sensors for activity and sleep detection
Measured metrics: heart rate, heart rate variability, sleep stages, hours slept, active minutes, steps, calories burned, distance travelled
Connectivity: Bluetooth Low Energy (Bluetooth 5.0)
Battery: Lithium Polymer, nominal capacity 24 mAh; typical battery life up to 6 days depending on usage
Weight: approximately 2.4 grams
How to use
Place the ring on the preferred finger ensuring a snug but comfortable fit so sensors maintain contact with the skin. Install the Amazfit-compatible app on your smartphone, pair the device via Bluetooth, and follow the app prompts to complete setup and allow relevant permissions. Wear the ring continuously to record sleep and daytime activity; sync periodically to view detailed trends, recovery scores and recommended actions in the app. Charge the ring when battery is low using the supplied charger according to the manufacturer’s instructions.
What to consider before purchase
Ensure the selected size (size 9) matches your finger measurements for reliable sensor contact and comfort
Confirm smartphone compatibility and that you are willing to use a companion app for data access and settings
Consider whether you require features not provided by a smart ring (on-screen display, standalone GPS, call handling)
Usage recommendations
For best results wear the ring continuously including overnight, keep the sensor area clean and dry, and perform regular app synchronisations. Use the recovery and sleep insights in the companion app to guide rest, nap timing and low-impact breathing exercises rather than relying on single-night readings.
