KNOWHEN® Ovulation Tracker App
The personalized Fertility Monitor App features a calendar with dates color coded based on your ovulation results to help you keep track of your unique fertility and ovulation cycle. You can use the "intercourse" button to track each day’s sexual activity. Press "Save" after selecting your input. All your future information will continue to be saved on the KNOWHEN® secure server. To fully use and experience all the benefits of the Fertility Monitor App, you will need to input the serial number provided in the KNOWHEN Ovulation Test kit package. Without the serial number, you will only have access to the current month’s data versus unlimited tracking of your information.
