The Lady Cycle mobile app is based on the most accurate method for natural family planning. It determines your most fertile days for conception and it tracks your physical and psychological well-being across your cycles (self-awareness).
Lady Cycle predicts your menstruation, ovulation, and fertile/infertile days - adapting to your personal menstrual cycle - based on an in-app implementation of the symptothermal method. The method was developed and tested by the NFP Workgroup. In a first independent scientific study, Lady Cycle was ranked on the very top with a perfect accuracy score.
