Ratings and Reviews
Basic and simple
This app does exactly what it says it is going to do. There are no bells or whistles. The one thing I miss is elevation. Using consumer-level GPS for elevation is an estimate, but in the mountains it can be useful. Put it in the update!
Terrible! Would not let me make a list of waypoints
With Family Sharing set up, up to six family members can use this app.
