Samsung has unveiled its latest software update for Galaxy smartwatches, One UI 8 Watch, based on Wear OS 6, bringing a suite of innovative health and wellness features. Launched on June 16, 2025, this update aims to redefine the smartwatch experience with advanced health tracking and a seamless user interface. From sleep analysis to fitness coaching, One UI 8 Watch is designed to keep Galaxy Watch users healthier and more connected. Let’s dive into the exciting features, rollout details, and what’s buzzing around this update!
What’s New in Samsung One UI 8 Watch?
One UI 8 Watch introduces a range of health-focused features that make Galaxy smartwatches smarter and more intuitive. Here’s a breakdown of the standout additions:
1. Antioxidant Index
This groundbreaking feature uses the BioActive sensor to measure carotenoid levels in your skin in just 5 seconds. Why does this matter? Carotenoids are antioxidants that combat premature aging and oxidative stress. Samsung Health now offers personalized dietary tips based on your antioxidant levels, helping you make healthier food choices.
2. Bedtime Guidance
Struggling with sleep? The Bedtime Guidance feature analyzes your sleep patterns and provides tailored recommendations to improve your rest. It tracks sleep onset and quality, syncing with Samsung Health to create a holistic sleep improvement plan. This is a must-have for anyone aiming to boost their wellness routine.
3. Vascular Load
One UI 8 Watch introduces Vascular Load tracking, which monitors cardiovascular strain. This feature provides insights into your heart health, helping you manage stress and exercise intensity to maintain optimal wellness. It’s a game-changer for fitness enthusiasts and health-conscious users.
4. Running Coach
Whether you’re a beginner or a seasoned runner, the Running Coach feature offers personalized training plans. It tracks your pace, heart rate, and distance, providing real-time feedback to improve your performance. Group running features also let you connect with friends for a fun, competitive edge.
One UI 8 Watch Rollout and Beta Program
Samsung has strategically planned the rollout of One UI 8 Watch, starting with the Galaxy Watch 8 series in July 2025. These devices will ship with the update pre-installed, offering users immediate access to the latest features. A Beta Program for the Galaxy Watch 7 and Galaxy Watch Ultra will also launch in July, allowing select users to test the software and provide feedback.
However, older models like the Galaxy Watch 4 and Watch 4 Classic face uncertainty. Their four-year software support, starting from August 2021, ends in August 2025. If the rollout extends beyond this date, these devices may miss out. The Galaxy Watch 5, 6, 7, and Ultra are confirmed to receive the update, ensuring most users can enjoy the new features.
Recent leaks spotted a One UI 8 Watch test build (R960XXU1CYF6) on the Galaxy Watch 6 Classic, hinting that the beta is close to launch. This internal testing phase underscores Samsung’s commitment to delivering a polished experience.
