When the app opens, you will be on the main screen. You will see your Name, GHIN number and current handicap index at the top. (If for some reason it opens on another screen, you can get back there by clicking on the Golf flag icon in the lower left of the bottom navigation bar.) You will see 4 buttons, under that is your score history.
There is a small drop down arrow which allows you to select a variety of ways to look at your scores (20 most recent, current year only, past 12 months etc.). There is also a small ? icon that has additional information.
