Periodical vs Petals
Side-by-side comparison of two open source alternatives
Periodical
This application calculates the fertile days according to Knaus-Ogino and can track menstrual symptoms. WARNING: It is not recommended to use this calendar to avoid pregnancy! There are more accurate methods, like measuring the basal body temperature. The data can be backed up on a memory card or "internal" memory, if present.
