Evolving into a personal health coach, the Galaxy Watch8 series helps users build tailored routines with tools for sleep guidance, running coaching, antioxidant and vascular load tracking. A soft-edged cushion design and built-in Gemini, Google’s AI assistant, offer both refined aesthetics and intuitive usability.

Samsung Newsroom got an exclusive early look at the Galaxy Watch8 series during Galaxy Unpacked 2025.

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 analyses sleep patterns over the past three days and recommends an ideal time to wind down.

Bedtime Guidance provides personalised 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, personalised feedback are essential. After a 12-minute run with the Galaxy Watch8 series, Running Coach analyses performance data, categorises running ability on a 10-level scale and generates a customised three- to five-week training program.

During runs, the feature provides personalised 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 colour-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 optimised for smaller displays — making essential information easier to view at a glance.
