We already know that Samsung is revamping its TouchWiz user interface for the upcoming Galaxy S5, and it appears that overhaul is going to extend to some of its built-in apps. Leaked screenshots of an unreleased S Health update reveal a new flat look that better fits Google’s design guidelines for Android 4.4 KitKat.

For those who haven’t used a Samsung smartphone with TouchWiz before, S Health is Samsung’s health and fitness tracker that allows users to record and monitor their daily activities, the food they eat, and their weight and statistics. It’s free and baked into most Samsung devices as standard.

Leaked screenshots obtained by SamMobile reveal S Health’s new user interface, which obviously follows the same design guidelines Samsung has been working with for its next-generation TouchWiz redesign. The app boasts a flatter, cleaner look with bright colors and easy-to-read fonts.

Most of the app’s basic functions remain the same in the new version, but there is a new new features that allows users to view their location on a map and control the music they’re listening to all from within the same screen while they’re working out.

SamMobile says these screenshots were taken from a firmware release for the Samsung “SM-G900H.” They are “unable to confirm if this is the Galaxy S5” at this time, but it certainly looks like this redesigned S Health app will rollout alongside Samsung’s new TouchWiz user interface.
