【實用健康app】Periodical|最夯免費app

This application calculates the fertile days according to Knaus-Ogino.

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.

If you have any further questions or want to help me with translations in other languages, please contact me via e-mail - thank you.
