After the woman enters the start date of her most recent period into her private account, the web app shows her where she is in her cycle and whether she is on a day when pregnancy is possible (fertile day) or unlikely (non-fertile day) according to the Standard Days Method of family planning. The information is provided both on a color coded calendar and on a virtual representation of CycleBeads®. She can also receive alerts telling her the day is a fertile or non-fetile day and reminding her when she is about to get her next period.
