In addition to the evaluation, trackle also shows you prognoses. They are displayed starting with the second trackle cycle and are based on a statistical evaluation of your past cycles. These prognoses will become more and more precise the longer you use trackle and will help you to know beforehand when you will likely be fertile and when not.

BUT: prognoses are not 100% certain predictions of your cycle, they are really just that: prognoses!


For contraceptive purposes, it is always necessary to check the first tab in the app with the current fertility display.
