Star Traveller is a clean and cool digital watch face. The bar on the left indicates the steps taken (10,000 corresponds to the full bar), the bar on the right indicates the remaining battery. At the bottom, there is the number of steps while at the top there is the Heart Rate value. The color theme can be chosen between the ten available in the settings.
There is a shortcut to the calendar on the date and two custom shortcuts respectively on the hour and on the steps. Always On Display mode shows time and date.

Notes about Heart Rate detection.

The heart rate measurement is independent of the Wear OS Heart Rate application.
The value displayed on the dial updates itself every ten minutes and does not also update the Wear OS application.
During the measurement (which can also be triggered manually by pressing the HR value) the heart icon blink until the reading is completed.
