## What is SymptoT°?

SymptoT° is an application that helps you to use natural birth regulation. This is a method of self-observation which allows:

. Every young girl and woman to find out more and learn about their body and their cycle.

. You to determine the beginning and the end of the fertility phase, based on the signs of mucus and temperature.

. Any couple to have a dialogue based on trust and tenderness, to make the responsible choice to welcome a new child or to space births, or to avoid pregnancy.

. To recognize the beginning of a pregnancy, the resumption of cycles after the taking of anovulants or following a pregnancy.

This method is based on the observation of:

 . Cervical mucus.

 . The basal temperature.

 . Sometimes you can also use the position and texture of the cervix.

In the help, you will find explanations on how to make the observations and what are the rules of interpretation to determine the fertile and infertile phases.

Examples are offered to better understand the course of a cycle and its interpretation.

But, for proper use of SymptoT°, it's important to contact and be trained by a monitor* in your country.


If you activate iCloud (with iCloud Drive) in settings, your data will be automatically backing up on iCloud.


Know your fertility, not only to better explore your femininity, but also increases your sense of responsibility. Self-observation methods, experienced within the couple are a source of greater dialogue, greater confidence and greater love.
