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 continued to be saved on the KNOWHEN® secure server. To fully use and experience all the benefits of the Fertility Montior 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.

Not helpful

I bought the device and had mixed results so logged into the app hoping it would help. It only lets you log your current day's results. I wanted to log the past few days hoping it would give me a sign into my fertility, but it does not give you that option to update any days other than today. So if you forget to log a day, out of luck!

Poor design

Completely unimpressive app that pairs with a device you purchase. It is not user friendly and is unattractive. I heard they are working on a update- hopefully they are changing everything.

Welp Login Fail

I paid for the silly thing and when I can actually use the app I'll update my review. Unable to log in
