About Periodical

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.

For tracking your periods with a minimum of fuss this is an elegant solution. Major praise for it being plain looking, and not covered in pink or flowers! Does what it says on the box.
