The Oucscru Smart Ring is a slim, all-day wearable that monitors heart rate, SpO2, sleep stages, steps and more while offering IP68 water protection and multi-day battery life.

Designed for both women and men, this rose gold smart ring blends jewelry-style looks with fitness-grade sensors. It pairs with iPhone and Android, syncs data with Apple Health, and uses a rechargeable 300mAh charging case for extended use. Lightweight at a thin 2mm profile, the ring aims to stay comfortable for continuous wear during daily activities and sleep tracking.

How accurate are the health readings from this smart ring?

The ring uses optical sensors and onboard algorithms to estimate heart rate, blood oxygen, temperature and HRV trends. While it provides useful day-to-day trends and alerts, it is not a medical device and should not replace professional testing.

• Continuous heart rate monitoring with trend graphs.
• SpO2 (blood oxygen) readings for general daytime and sleep observations.
• HRV and body temperature for stress and recovery patterns.
• Syncs data to the SmartHealth app and Apple Health for consolidated review.

What sleep insights will I get while wearing the ring?

The Oucscru ring tracks sleep stages—deep, light and REM—to help you understand sleep duration and cycles. It compiles nightly summaries and highlights patterns so you can compare sleep quality over weeks.

• Detailed breakdown of deep, light and REM sleep.
• Automatic sleep detection—no manual start/stop required.
• Nightly score and trend charts in the app for comparison.
• Recommendations based on observed sleep patterns (informational only).

How long does the battery last and how do I charge it?

A single full charge delivers approximately 5–7 days of typical use, depending on how often sensors and notifications are active. The included 300mAh charging case extends runtime and uses USB charging for simple top-ups at home or on the move.

• 5–7 days per charge under normal usage.
• Compact 300mAh charging case for extra cycles while traveling.
• USB charging cable included for universal compatibility.
• Quick docking design—magnetic contact for stable charging.

Can I wear this ring while swimming or showering?

Yes—the ring carries an IP68 rating, meaning it is designed to handle water exposure for daily use, including swimming and showering. Follow care recommendations to maintain the finish and sensor performance over time.

• IP68 water protection suitable for swimming and bathing.
• Durable polished inner surface for comfortable wet wear.
• Avoid strong chemicals and saltwater long-term to protect plating.
• Remove for heavy impact or contact sports to prevent damage.

Who is this for: The Oucscru Smart Ring is a good fit for people who want continuous health and sleep trends in a discreet, jewelry-like form—those who prefer wearing a ring instead of a wrist device, frequent swimmers who need water protection, and anyone who values battery longevity and app syncing without subscription fees.
