Tizen's look is similar to that of smartphones or tablets with the battery life displayed on the top of the screen with commonly used apps at the bottom. The touch screen allows for users to select apps or use the scroll bar on the right side of the display. For those who have used a smartphone before, it'll look familiar.
The UI on the Apple Watch is different from any of the company's other products. The app icons look the same, but that's about it. Users navigate through the watch menus, carousel through apps and zoom in and out of maps or images using the Digital Crown on the side of the watch. The touch screen of the Apple Watch is also a first of its kind, as it detects the impact of touch, meaning a harder tap on the screen is a different command from a softer press.
