You most likely DO NOT need this Companion App. We STRONGLY recommend you use the mobile-friendly dynamicWatch website https://dynamic.watch to manage your routes and settings on your phone. dwMap on your watch syncs DIRECTLY with your dynamicWatch account. Although we offer this iOS/Android phone app, the dwMap Premium Companion App, it only exists for a small number of UNUSUAL cases and most users do NOT use it. The website is mobile-friendly and works great on your phone, and this is how the MAJORITY of our users use dwMap. The dwMap Premium Companion App does NOT work with routeCourse, Rain and Wind, or mapField.
