There are 31 categories of data that you can enter in Clue. Three categories can be displayed on a screen at once. The remaining buttons can be found by tapping on the "plus" button or by going to "Tracking Categories" in the "More" section.
The buttons can be reorganized so you can select which buttons are seen on which screens.
- Go to the calendar and tap on a day.
- Press and hold one of the category buttons, and wait for it to highlight.
- Drag the button to wherever you'd like it to be.
