Navigation Watch is a free Android app developed by Prog Apps under the Travel & Navigation category. It is a convenient app that allows users to navigate through their smartwatch while using their phone's Maps app. The app is compatible with Fitbit, Garmin, Huawei, and Wear OS watches.

To use Navigation Watch, users must first install the app on their phone and grant the necessary permissions. Once installed, users can start a Maps navigation on their phone and launch Navigation Watch from the app menu on their watch. The directions will then be shown on the watch, with incoming turns signaled by vibrations. Left turns are signaled via two vibrations, while right turns are signaled via three vibrations.

It is important to note that users must also install the free wearable "Navigation Watch" app on their smartwatch. The app displays turns, distance, direction, speed, and arrival time, but does not show a map. Additionally, the Wear OS app is not standalone and requires phone interaction in order to function.

Overall, Navigation Watch is a useful app for those who prefer to navigate through their smartwatch while using their phone's Maps app. It is easy to use and compatible with a variety of wearable devices.
