The outer circle contains numbers which count down the number of days to your next period. The number of days is calculated from the history which you have entered. The more history that you record, the greater the accuracy of the countdown. If the button is accidentally pressed, then the history can be edited or deleted in the History screen.

As well as the countdown circle, your next period due is written below the round button in text once you have entered enough data.

History Screen

In this screen all your period history is recorded and saved. By clicking on a history date range, the details for that date range will pop up. You can edit, delete, add notes and save any changes. This screen is also used to ADD prior history to help initiate more accurate calculations of your cycle.
