Periodical

Menstrual/period calendar

This application calculates the days of fertility according to Knaus-Ogino. The data can be backed up on a memory card, if present.

WARNING: It is not recommended to use this calendar to avoid pregnancy! There are more accurate methods, like measuring the basal body temperature.

If you have any further questions or want to help translating the app, please contact upstream.
