The "S4U RC ONE - USA" is a special edition of the S4U RC ONE Collection. This WearOS Watch Face app features a realistic analog dial inspired by classic chronographs. The watch face creates an extraordinary 3D effect, making it feel like you're wearing a real watch. With this app, you can customize the watch face and set up to 6 shortcuts to your favorite apps for quick access.

The watch face displays the weekday and day of the month in the right area, an analog pedometer (with a maximum of 40k steps) at the bottom, and the battery status%) on the left. Additionally, it has a minimal always-on display, ensuring that you can always see the time.

To customize the watch face, simply press and hold the display, then push the customize button. You can swipe left or right to switch between different customizable objects and swipe up or down to change the color options of the objects.

Setting up shortcuts is also easy. Press and hold the display, push the customize button, and swipe from right to left until you reach the "complications." The 6 shortcuts will be highlighted, allowing you to set your desired apps for quick access.

The app also includes a heart rate measurement feature. By tapping the heart rate indicator, the measurement process begins, and a green flashing LED light appears during the process. The heart rate is automatically measured every 30 minutes.
