While an Apple Watch has some basic golf GPS features, it's not advanced enough to be a standalone golf GPS device. However, the GolfShot Pro app can be used as a high-end golf GPS with most of the features available on a golf GPS watch. The app uses GPS to provide accurate yardages, preloaded courses, green views, shot tracking, club selection, and record shot distances. The app also offers additional features like slope functionality and virtual caddie for an extra cost. So, if you own an Apple Watch, you can benefit from a high-end golf GPS experience by using the GolfShot Pro app (for additional fees).
