Problem
Many people struggle to obtain accurate, continuous sleep data because traditional sleep trackers are bulky, require frequent charging, and often cause discomfort during wear, leading to inconsistent monitoring and missed opportunities for early health interventions.
Solution
SOXAI offers the SOXAI RING 2, a ultra‑thin (6.7 mm wide, ~2 g) smart ring that continuously records heart rate, heart‑rate variability, blood‑oxygen saturation, skin temperature and motion using its patented Deep Sensing™ multi‑wavelength optical sensor. The ring’s titanium alloy construction provides a comfortable, durable fit, while a 14‑day battery life (60–120 min charge) eliminates the need for daily charging. All data are synced via BLE 5.0 to a free mobile app, where AI‑driven algorithms—validated by Japanese Sleep Society experts and academic research—produce sleep‑stage scores, breathing‑irregularity alerts, and personalized improvement recommendations without any subscription fees. The solution enables users to monitor sleep quality reliably at home or on the go, turning raw biometric signals into actionable insights.
Target Audience
Primary users are health‑conscious adults, athletes and individuals with sleep‑related concerns who seek accurate, hassle‑free sleep monitoring, as well as clinicians and wellness programs that require reliable biometric data without recurring subscription costs.
