Heygolf app has two applications: for learners and teachers. Heygolf app helps users easily search and view golf instructor information and lessons that the instructor has updated so that the user can register for the instructor and course that is right for them. After participating in the instructor’s course, users can write a review about the instructor of that course. The Heygolf Pro app helps teachers update their personal information, lessons, and courses to promote themselves on the Heygolf app. Instructors can directly create courses or register to participate in amateur courses and tournaments organized by Heygolf to earn extra income. Through the real-time chat feature, teachers can directly advise users about their lessons and introduce courses suitable to the user’s level and needs.
