The app automatically calculates your ovulation day based on your menstrual cycle data. To use this feature, make sure you regularly update the start and end dates of your menstruation, as these determine your ovulation day.

For users who are planning pregnancy or tracking fertility, it’s helpful to know that ovulation usually occurs about 14 days before the start of the next menstruation, but this can vary depending on individual characteristics. The app uses this data to accurately predict ovulation and informs you about upcoming fertile days.

If you have irregular cycles or want more accurate tracking, you can input additional data such as basal body temperature or ovulation test results. This will help improve the precision of the prediction.
