@egika @egika Thanks for the clarification. I assumed that if the process worked on Android it would work on iPhone as well.
My Traverse manages the whole process of converting track to route internally. All the code is in the watch. To me, making the phone a part of the process is a retrograde step. But at least with Android it can be done entirely via Bluetooth.
If I were an iPhone user I would contact Suunto and ask them to have a look at this.
