Q: Why does the USAY Ring 1 have lights? What is "Real-time Feedback"?
Most wearables only record history—telling you what happened yesterday. Usay Ring 1 is designed for the "Now."
We prioritize Stress and Body Energy monitoring. The discreet LED lights on the ring provide immediate feedback on your current state, so you don't need to open the App for everything.
- High Stress Alert: If the ring detects that your physiological stress is at a medium to high level, it will send out a gentle pulse to remind you to relieve stress.
- Energy Check: It visualizes your body battery in real-time, helping you decide whether to push for a workout or rest.
Note: While you can view detailed history like Steps or Sleep Stages in the App, we believe metrics like Stress require immediate attention.
Q: Does the light feature affect battery life?
Yes, maintaining this "Real-time Awareness" consumes more power than passive recording. That is why Usay Ring 1 provides 3-5 days of active battery life. However, with the included Charging Case (which provides 50+ days of total power), you can easily top it up anytime, ensuring you never miss a beat.
Q: What is the AI Health Assistant?
The Usay App features a built-in AI Health Assistant that supports voice and text interaction. Instead of digging through complex charts, you can simply ask, "How did I sleep last night?" or "Why is my stress high?", and the AI will analyze your data to give you a direct, conversational answer.
Q: Do I need a monthly subscription to view my health data?
No. In our current plan, Usay offered an extended free access period, making it an ideal gift without the need for an immediate subscription. During this period, you will be able to view and use your core health indicators, including sleep, stress, heart rate and blood pressure trends, at no additional cost.
In the future, Usay may introduce optional and reasonably priced subscription plans to support advanced features and continuous product improvements. Any such plan will remain user-friendly.
Q: Is the Al Health Assistant free to use?
Yes, the standard version is included with your device.
The Usay Ring 1 includes a generous Daily Free Plan for the AI Assistant (supporting approx. 20 text interactions or 10 voice interactions per day).
This allocation is sufficient for the vast majority of users' daily health inquiries. We believe in providing actionable insights without mandatory hidden costs.
Q: Can USAY Ring 1 measure Blood Pressure?
Yes, this is one of our key differentiating features. Usay Ring 1 monitors Blood Pressure Trends (both day and night).
Unlike typical smartwatches, our algorithm focuses on long-term management. By tracking the trend of your blood pressure variations over time, we help you identify potential risks and lifestyle impacts earlier.
Disclaimer: This feature is for wellness tracking and trend analysis, not for medical diagnosis.
Q: How accurate is the Sleep Tracking?
We use a 4-Stage Sleep Algorithm comparable to top-tier industry standards. It accurately identifies:
- Awake
- Light Sleep
- Deep Sleep
- REM (Rapid Eye Movement)
It also tracks HRV (Heart Rate Variability), nighttime blood oxygen (SpO2), and sleep temperature variations to provide a comprehensive Sleep Quality Score.
Q: How long does the battery last?
The USAY Ring 1 provides 3 to 5 days of battery life on a single charge.
- The variance depends on how frequently the Smart Lights and real-time monitoring features are triggered.
- Heavy Use: ~3 days.
- Light Use: Up to 5 days.
Q: How does the Charging Case work?
Every USAY Ring 1 comes with a powerful portable Charging Case (similar to wireless earbud cases).
- The case holds enough power to recharge your ring multiple times, providing a total of 50+ days of autonomy without needing a wall socket.
This makes it perfect for travel—just put the ring in the case to top it up whenever you take it off.
Q: How do I choose my size? (Do not skip this!)
Smart ring sizing is unique. Do not use your standard jewelry size.
- Select the "Free Sizing Kit" option at checkout.
- We will ship the kit first. Wear the plastic sizer for 24 hours (including while sleeping) to ensure comfort.
- Scan the QR code in the kit to confirm your size, and we will ship your actual ring.
Q: Can I use a sizing kit from Oura, RingConn, or Ultrahuman?
No. Each brand uses different sensor placements and inner-shell designs. Using another brand's sizer will likely result in a poor fit and inaccurate data. Please only use the official Usay Sizing Kit.
Q: Which finger is best for Usay Ring 1?
For the most accurate data (especially for Blood Pressure Trends and Sleep), we strongly recommend wearing the ring on your Index Finger. The Index finger has strong arterial blood flow, ensuring the highest signal quality for our sensors.
Q: What is the ring made of?
The outer shell is made of aerospace-grade Titanium with a PVD coating—lightweight yet highly durable. The inner shell is molded from hypoallergenic epoxy resin, designed for 24/7 comfortable wear.
Q: Is the ring waterproof?
Yes, it is rated IP68. You can wear it while washing hands, showering, or swimming.
