Background of Development and Reason for Support: High Design Quality and Functions Focused on "Sleep"

In modern society, "declining sleep quality" has become a major issue due to information overload and digital dependency. The smart ring market is becoming more active due to rising health consciousness and improvements in smart device performance. However, designs have traditionally been simple and favored by men, typical of gadget products. OraMemoRing was designed under the supervision of a world-renowned designer, aiming to expand choices and create a design that women and others would want to wear daily. As a result, its "high design quality that blends into daily life," unlike conventional smart rings, was highly evaluated, garnering significant support.

Furthermore, it focuses on "sleep," a major challenge for modern people immersed in digital technology, and is equipped with highly accurate sleep measurement as its main function. It visualizes daily condition and supports the establishment of better lifestyle habits.

In addition, it can measure various condition data in a timely manner, allowing users to grasp their "current" state in real-time, which is another significant feature.

Customer Testimonials

– I bought it because I have short sleep duration and concerns about sleep quality. It's comfortable to wear without feeling intrusive, and I also like it as an accessory. Being able to manage sleep, calorie consumption, steps, and exercise is very useful. My sleep duration is gradually increasing, and I feel my physical condition improving. I will continue to use it with love.

– I use it every day! I have a smartwatch, but wearing both allows me to see detailed data, and it's convenient to wear even when my Apple Watch is charging.

– The long battery life is the best! I switched from another company's smartwatch! Also, the step count sensitivity is great!
