Unless you started Handicapper Plus by loading a Race file (.hmrx extension), this is the first screen you will see when you start HandicapperPlus Mobile. Only the Options menu, New Race button, Browse Races button, and Import Races button are available.
The first time you use HandicapperPlus, the only useful thing you can do is click on New Race, as there are no saved races to browse. Once some races have been created and saved, clicking Browse Race will take you to a screen where you can load, delete, or share previously saved race data.
The Options menu appears in various positions on different devices, but is usually hidden in the dark area on the bottom lower left of your device (invisible until clicked, and next to the back button area on the device in the picture). Often, the Options menu will appear in the upper right, and on some devices is represented as three white squares in a column.
