Build with Watch Face Studio powered by Samsung with an API Level 30+. Tested on Samsung Watch 4 and Watch, all features, and functions worked as intended. The same may not apply to other Wear OS devices. Should the app fail to install on your watch, it is no fault of the designer/publisher. Check your device compatibility with Play Store App and/or reduce redundant apps from the watch and try again. Refer to store listings for more details.
