Background and Concept of Product Development

Modern health challenges are not due to a lack of knowledge, but rather the difficulty in understanding how general health information applies to one’s own body. While abundant health information exists, continuously correlating it with personal physiological data remains challenging.

'RingConn Gen 3' was developed to address this gap—an integrated wellness device that combines real-time data with long-term insights in a single ring. By taking the form of a familiar everyday item—a ring—it supports 24/7, year-round health tracking with minimal wearing burden.

Key Features of the New 'RingConn Gen 3'

- No Subscription Required—Use indefinitely without additional fees. While major competing smart rings require monthly subscriptions, RingConn Gen 3 provides all advanced features without any subscription. Users enjoy continuous updates and full functionality post-purchase with no extra costs, designed for long-term, worry-free use.

- Vascular Health Trends—Visualize your vascular condition daily. Using proprietary sensor data, the device continuously monitors vascular condition from daytime activities through sleep. Automated trend analysis combines physical load, sleep, stress, and activity data across day and night, visualizing subtle daily changes. These insights accumulate over time, supporting smarter health management.

*Note: This function does not measure blood pressure and is not intended for medical diagnosis.

- Long-Lasting Battery—Up to two weeks without charging. A single charge provides 10–12 days of battery life with vibration feedback enabled, and 11–14 days when disabled. When paired with the portable charging case, users can continue using the device with confidence even during travel. The case is compatible across all sizes and models and can be conveniently charged via USB-C cable.

- Wellness Vibration Alerts—Receive gentle ring vibrations for body changes. When changes such as heart rate fluctuations or prolonged sitting are detected, the ring delivers a gentle vibration to alert the user in real time. Supports health alerts, sedentary reminders, and low-battery notifications. Users won’t miss important health cues, even without keeping the app open.

- Condition Alerts—Detect changes in your body’s patterns and receive rest recommendations. Heart rate, HRV, and body temperature are monitored 24/7, 365 days a year, with timely notifications on daily condition changes as reference information. Helps users recognize deviations from their usual patterns and prompts them to reconsider rest and lifestyle rhythms.

*Note: This function is not intended for diagnosis, prediction, or prevention of specific symptoms.

- Sleep Breathing Monitoring—Comprehensive monitoring of breathing during sleep. Tracks all four sleep stages and breathing changes throughout the night to support next-day condition assessment. Even subtle breathing variations during sleep are monitored via continuous SpO₂ measurement (every 2 seconds), with detailed reports visualizing sleep quality.

*Note: This function is not intended for diagnosis or treatment of conditions such as sleep apnea.

- Ergonomic Design—Comfortable enough to forget you're wearing it. RingConn’s unique 'rounded inside, square outside' structure naturally fits the shape of the finger. Weighing only 2.5–3.5g, with a width of 6.8mm and thickness of 2.3mm, its ultra-slim, lightweight design eliminates the 'wearing something' feeling common with smartwatches, allowing all-day wear. With IP68/ATM10 (100m depth) waterproofing, it is suitable for swimming, bathing, and various other scenarios.

Acalie Staff User Review: A 47-Year-Old with Hypertension and Sleep Apnea Tries the RingConn Gen 3

Comment from Dr. Yohei Sato, Medical Doctor

As a health professional, I used to be confident in managing my own health. That confidence was shaken when I started using RingConn Gen 3. Through data, I realized, 'I thought I knew my body, but I didn’t.'

Changes in my sleep score after morning exercise, data trends during fatigue buildup—when my vague sense of 'feeling tired' began aligning with actual metrics, I could naturally decide to rest before getting sick. What I hadn’t noticed wasn’t just sleep or fatigue. With a family history of vascular concerns in middle to later age, the vascular health trend feature now allows me to effortlessly monitor daily changes. As a self-employed individual working from home, I often sit too long without realizing it. The sedentary alert warns me before fatigue accumulates.

These insights accumulate because data collection never stops. Thanks to the ring’s natural, comfortable fit, I can wear it all day. With up to 14 days of battery life, quick charging, and early low-battery vibration alerts, I can charge calmly even the night before a business trip. It’s this sustainable design that enables continuous awareness. Gradually, I’m beginning to understand my body.

As a medical professional who values evidence, I confidently recommend this as a tool that bridges general health knowledge with personal bodily data.
