The OneUI 8 Watch upgrade, which was unveiled alongside the Galaxy Watch 8 and Watch Ultra (2025), represents a significant feature advancement for the Galaxy Watch. Samsung surprised us by releasing the major Wear OS 6-based software, with the original Watch Ultra getting first dibs, even though it was anticipated that it would arrive later for earlier Watch models.
It was first believed that the new Galaxy Watch 8 would have a brief exclusivity period with the new operating system, so the release of OneUI 8 Watch is rather unexpected. Samsung has now formally said that the OneUI 8 Watch would be released before the Galaxy Watch Ultra from last year.
Numerous users – including those with carrier-tied and unlocked models – confirmed receiving the update. With a size of roughly 1.9 GB, the OTA update is quite large, however it may differ depending on the watch model. A patch will be sent to beta participants at the same time to move them to the stable version.
Regarding the changes and new features, OneUI 8 Watch seems to be a noteworthy turning point. As part of Samsung Health, it does offer a new generation of wellness and health tracking tools.
New smart features and customizations
The Now Bar from OneUI 8 is one of the many UI improvements and refinements that OneUI 8 Watch offers in addition to the new tracking tools. It functions with the majority of first-party apps and workouts and shows the current tasks as a widget at the bottom of the watch face.
Additionally, the update allows users to receive personalized watch face recommendations and merge numerous app tiles into one. Now, the double pinch gesture can be used to take a picture, dismiss notifications, and control music.
Vital Sleep Tracking Tools
“Bedtime Guidance” is a new feature in the update that, as the name implies, offers tailored bedtime recommendations based on a user’s activities and sleep habits. To assist users in addressing irregular sleep patterns and improving their quality of sleep, it is integrated with sleep coaching.
Another sleep-related tracking tool is Vascular Load. This gauges the vascular system’s circulatory stress as you sleep, which is a crucial sign of your general health.
Running coach and mindfulness
Athletes and runners would also profit from OneUI 8 Watch’s new Running Coach feature. Personalized training programs are offered by this fitness gadget according to users’ fitness levels and objectives. In order to analyze a runner’s level of fitness and generate a performance analysis, they must essentially complete a 12-minute test. During runs, real-time coaching is also available.
Mindfulness, a well-known function that is new to the Galaxy Watch, is a technique for stress and anxiety management. It includes breathing techniques to help lower stress levels.
Antioxidant Index
One of these new features is the Antioxidant Index, which measures the antioxidant-producing carotenoids in a user’s skin using a non-invasive technique. To determine the antioxidant level, users must press their finger against the Galaxy Watch’s BioActive sensor for five seconds. A score ranging from 0 to 100 is displayed for the outcome, with 100 being the highest and most suitable.
As usual, a person’s level of antioxidants reflects their overall health. The tool also suggests ways to improve carotenoid levels, such as eating more fruits and vegetables.
Additionally, the upgrade allows users to receive personalized watch face recommendations and merge numerous app tiles into one. Additionally, the double pinch gesture may now be used to take a picture, dismiss notifications, and control music.
Given that it has the same sensor and processor as the Galaxy Watch Ultra, the majority of these capabilities are also intended for the Galaxy Watch 7, though we are unsure of when the update will be available for that wristwatch. Additionally, there is no timeline for previous Galaxy Watch models.
