watchOS

watchOS is the operating system in the Apple Watch. As a platform for applications, it is very similar to iOS, tvOS, and to a lesser extent macOS. Apple Watch can be used to view OpenStreetMap-based maps. However, due to the extremely small screen size, it is still relatively uncommon for watchOS applications to feature maps.

Applications

These applications let you use OpenStreetMap on your Apple Watch:

Application	Map	Location tracking	Search	Directions	License	Price	Rating
