Charti was developed to aid the tracking of a woman's fertility using the cervical mucus method (sometimes known as Billings Ovulation Method).

This method requires instruction to use properly, which this app does NOT provide. It is merely a handy replacement for pen, paper, and stickering.

This app does NOT guarantee to avoid pregnancy, nor to achieve pregnancy. It merely tracks signs of fertility.


*This app does NOT track temperature (symptothermal method), which is a separate fertility indicator.
