What do the ring's readings show?

The Oucscru Smart Ring collects continuous optical sensor data to provide trends and comparative metrics for heart rate, SpO2 (blood oxygen), and sleep stages. It’s designed for general fitness tracking and lifestyle awareness. Not a medical device; not intended to diagnose, treat or prevent any condition.

• Continuous heart-rate monitoring for resting and active periods
• Blood oxygen (SpO2) readings to track trends during day and sleep
• Sleep staging with deep, light, and REM estimates and duration reports

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

When fully charged, the ring typically runs 5–7 days depending on usage and sensor activity. The included 300mAh charging case extends field use and provides convenient USB charging so you can recharge the ring on the go or from a wall adapter at home.

• Ring runtime: approximately 5–7 days per full charge
• Charging solution: compact 300mAh case with USB input
• Quick connect and charging indicators on the case for easy monitoring

What size should I buy and how comfortable is the ring for daily wear?

Measure your finger circumference and consult the Oucscru size chart before ordering to ensure a snug but comfortable fit — the manufacturer strongly recommends sizing to avoid returns. The ring is only 2mm thick with a polished inner surface for smooth wear during sleep, exercise, or daily tasks.

• 2mm thickness and polished inner surface for comfort
• Durable finish designed to resist knocks and daily wear
• Ring protector included to prevent accidental damage

Can I use features like camera control and family health sharing?

Yes — the ring supports remote photography so you can trigger your phone’s shutter by quickly shaking your finger twice. The SmartHealth app also allows multiple family accounts to share and view connected health data for convenient household monitoring and check-ins.

• Remote shutter control with two quick finger shakes
• Multi-user family sharing through the SmartHealth app
• Compatible with both iPhone and Android without subscription fees
