The Home screen is split into two sections. The top section shows the number of strokes for a given hole. The bottom section is where the user specify the par of the current hole, increment the stroke count for the current hole and to skip to the next or go back a hole.
One user-centric improvement in the latest version (1.5) is that pars of holes are not reset unless the user changes them manually one hole at a time. This is great for users who plays the same course over and over again. It would be nice if there is an option to save the pars and name it (ie. Golf course name) before overriding them.
