Samsung has officially launched the One UI 8 Watch, a major software update for its Galaxy Watch lineup, introducing a suite of next-gen health monitoring tools aimed at helping users build sustainable wellness habits. Currently available in beta for Galaxy Watch5 series and newer models, the update brings AI-powered insights across sleep, heart health, fitness, and nutrition.
🛌 Bedtime Guidance: Smarter Sleep Coaching
The standout feature, Bedtime Guidance, analyzes three nights of sleep data to recommend an optimal bedtime based on your circadian rhythm and sleep pressure. It also offers sleep coaching, environment optimization tips, and can detect signs of sleep apnea—helping users recover from irregular sleep patterns.
❤️ Vascular Load: Heart Health Under the Microscope
The new Vascular Load tool measures stress on the cardiovascular system during rest, flagging abnormalities and offering insights into how lifestyle and stress impact heart health.
🏃 Running Coach: Personalized Fitness Plans
Designed for runners of all levels, the Running Coach feature creates custom training programs based on a 12-minute assessment run. It adapts over time to help users train for 5Ks, marathons, and everything in between—while minimizing injury risk.
🥕 Antioxidant Index: Nutrition Meets Wearable Tech
Using a light-based BioActive Sensor, the Antioxidant Index measures carotenoid levels in the skin in just five seconds. This provides real-time feedback on dietary quality and encourages healthy aging through better nutrition.
🌍 Availability and Vision
The One UI 8 Watch beta is currently rolling out in South Korea and the U.S., with a broader release expected later this year. Samsung says the update reflects its commitment to holistic health management, offering instant feedback and actionable insights to support long-term behavior change.
Stay tuned for rollout updates and device compatibility.
