-The app allows you to track different intensities of bleeding. On the chart and on the calendar, bleeding values are colored in different shades of red. The darker, the more intense your bleeding. Every bleeding value that is not excluded is taken into account for fertility calculation and prediction for the start of next cycles.

Every bleeding value that is not excluded is taken into account for fertility calculation and period predictions.
 
 Excluding bleeding values is for tracking bleeding when it's not marking the start of a new cycle or the continuation of menstrual bleeding the day(s) before, e.g. bleeding caused by ovulation or a miscarriage.
