Lengths are measured along each hole's line on OpenStreetMap, so they can differ from the club's card. A bunker between two holes counts on both.
The app
On your iPhone and Apple Watch, Number & Line turns this map into a yardage book, with distances to the front, middle and back of each green from where you stand. You can plan each hole at home and get club advice from your own distances and the day's wind.
The app is coming soon to the App Store, and this course is already built for it.
