Good Q… Most of our crew uses Dawn Patrol with the Apple watch. For me it was the killer app that I switched over from Android phone ==> Another Foiling addiction story…
The apple watch w/ cell service is handy when the DW attempt turns into a character building session and you have to call for an alternate pickup location…
Wind Speed is a good one for winging…but people have noticed wacky things if you run too many GPS apps on your watch at once, the symptom is that the lines go straight and jagged.
