What Is One UI 8 Watch?
One UI is Samsung’s custom software skin that runs on its Galaxy smartwatches. The One UI 8 Watch update refines the experience by making health and productivity data more accessible and easier to understand, all within a sleek and simplified interface.
This version was first introduced with the Galaxy Watch8 series, but is now rolling out to the Galaxy Watch Ultra, with plans to expand to more previous Galaxy Watch models soon.
Key Features of the One UI 8 Watch Update
Samsung is packing a lot into this update. Here's what Galaxy Watch Ultra users can look forward to:
1. Advanced Health Tracking Tools
The update puts a stronger focus on motivational health insights. New tools include:

Running Coach – Offers personalized, real-time feedback during your run. It adjusts to your fitness level and helps you stay on track with training.
-
Vascular Load – Gives you deeper insights into how your workouts are impacting your cardiovascular system.

It pulls everything into one view, so you’re not swiping endlessly to find what matters most.

The new Now Bar keeps your most recent activities and open apps easily accessible. Whether you’re tracking a workout, setting a timer, or checking your schedule, you won’t lose your place.

The Galaxy Watch Ultra was already a rugged device made for outdoor adventurers, and One UI 8 Watch only strengthens that claim.
With military-grade durability, water resistance, and a long battery life, the Watch Ultra is perfect for hiking, biking, and everything in between. The new update ensures that all the powerful features work seamlessly—even in challenging environments.
And with titanium finishes (including the new Titanium Blue), it’s built to look as good as it performs.
One UI 8 Watch on Other Models
Samsung confirmed that the One UI 8 Watch update will be gradually rolled out to other models. This includes devices in the Galaxy Watch5 and Galaxy Watch6 series.
However, exact availability can vary based on your region, the watch model, and your paired smartphone.
