Bedtime Guidance: Say Goodbye to the Monday Blues
The Monday blues often stem not just from fatigue but from a disrupted weekend sleep cycle. To help recalibrate daily routines, Bedtime Guidance analyzes sleep patterns over the past three days and recommends an ideal time to wind down.
▲ Bedtime Guidance provides personalized recommendations based on the user’s sleep data from the past three days.
Vascular Load: Monitor Cardiovascular Health During Sleep
Vascular Load tracks stress on the vascular system while the user sleeps.
The feature incorporates related data — such as sleep duration, physical activity and stress levels — to offer a more holistic view of overall wellness.

Running Coach: Improve Performance With Real-Time Feedback
To help prevent injury while running, proper pacing and real-time, personalized feedback are essential. After a 12-minute run with the Galaxy Watch8 series, Running Coach analyzes performance data, categorizes running ability on a 10-level scale and generates a customized three- to five-week training program.
During runs, the feature provides personalized feedback guidance. Afterward, detailed workout summaries and motivational messages are shared.

Antioxidant Index: Track Carotenoid Levels in Seconds
Healthy aging starts from within. The Galaxy Watch8 series introduces the Antioxidant Index — a first-of-its kind smartwatch feature that measures carotenoid levels in the body.
By placing a thumb on the BioActive Sensor on the back of the watch for five seconds, users receive both a numerical score and a color-coded result representing their antioxidant status. The feature makes it easy to monitor aging-related health, offering intuitive insights into dietary and lifestyle habits. For example, a sky blue reading indicates a sufficient intake of carotenoid-rich foods like leafy greens and carrots.

Multimodal AI and One UI 8 Watch: Access Smarter Features
The Galaxy Watch8 series is the world’s first smartwatch to come equipped with Google’s Gemini. Even when hands are full, voice control allows users to operate key functions — offering intuitive support during workouts and daily routines.
For example, saying “start a 300-calorie circuit training workout” prompts Gemini to launch Samsung Health for seamless exercise tracking.
▲ Gemini enables hands-free control through voice commands.
Debuting with this release, One UI 8 Watch introduces a redesigned tiles optimized for smaller displays — making essential information easier to view at a glance.
