Smart Ring 38mm Gold

The Aoyool SR300 is a 38mm gold smart ring designed for continuous wellness tracking. It monitors heart rate, blood oxygen and sleep stages around the clock. The device suits men and women who want a lightweight, screen-free wearable for daily health insights without a subscription fee.

Sustained 24-hour monitoring

New 5.0 sensors record heart rate, SpO2, stress and HRV data throughout the day and night. The ring automatically logs deep sleep, light sleep, eye movement and wake periods. A 60 MB onboard buffer stores readings between syncs, while the lithium-polymer cell delivers up to five days of operation per charge.

Simple sizing and app setup

Buyers must measure finger circumference against the supplied chart before ordering to ensure a secure fit. The ring pairs via Bluetooth with Android 5.0+ or iOS 9.0 devices through the SmartHealth app. An IP68 rating allows immersion during swimming or showering. The touch surface supports remote photo capture and family care sharing features.

Questions about this item

Does the ring generate noticeable heat or drain its battery quickly during continuous 24-hour monitoring?

The ring runs cool on the finger and delivers 3-5 days of operation from a 1-2 hour charge, so daily all-day tracking does not cause overheating or rapid power loss.

What smartphone operating system version must I already have to pair the ring and view data in the SmartHealth app?

You need a phone running Android 5.0 or later, or iOS 9.0 or later, to connect via Bluetooth and use the companion app.

Will the ring still sync and show sleep or activity data if I keep using an older phone that meets the minimum OS requirements?

Yes, any handset that satisfies Android 5.0+ or iOS 9.0+ will pair with the ring and display 24-hour health metrics in the app.
