It is designed to provide a comprehensive solution for golfers who want to improve their game. The app offers a range of features, including automatic recognition of the hole system, distance measurement, altitude difference information, green slope difference, and customized statistics.

One of the major strengths of Golfnavi is its ability to recognize the hole system automatically. It supports 60,000+ courses worldwide, including 350+ golf courses in Korea. It also provides altitude difference information for the first time in the world, which is a unique feature. Moreover, it supports high-resolution maps, two (left/right) green system, and green slope images. The app provides voice guidance, and users can save and view their scores in the scoreboard menu.

However, it is worth noting that due to the "WHS (Wear Health Service)" API, Golfnavi for GalaxyWatch can only be used on Samsung Galaxy Watch 4 and Galaxy Watch 4 Classic models. Furthermore, after the test period, users will need to purchase a yearly subscription. Overall, Golfnavi for GalaxyWatch is an excellent golf GPS solution that provides accurate and comprehensive information to golfers.
