trackle evaluates according to the rules of the symptothermal method and needs information on cervical mucus and a cervical mucus peak in addition to the temperature peak. 

In concrete terms: The cervical mucus symptom also follows a curve – in this context we call it “quality”. There has to be at least one cervical mucus peak, meaning a high-quality entry (f, s, or s+), during a cycle, followed by three days with lower quality. The more liquid and stretchy, the cervical mucus, the higher the quality, because this kind of mucus is what makes sure the sperms are comfortable, well nourished and can move around easily. The cervical mucus peak is independent of the temperature curve (but usually coincides).

That means: without entries on cervical mucus in the app, trackle does not evaluate at all. 

Our tip for cervical mucus observation: every time you visit the toilet, wipeyour vaginal entrance with toilet paper or a clean finger before you use the toilet and observe what you feel and see. In the evening, enter the best cervical mucus you observed during the day. It is important to observe the cervical mucus several times a day, as its quality can change throughout the day due to hormonal changes.
