As a Husband it has helped me keep track of my wifes periods and ovulation times with clock work precision. It has helped us get pregnant several times. I highly recommend it to those newly weds and those trying to get pregnant. The only thing I would add is that it should have an inbuilt reminder and alarms system to remind you of the fertile days. if you dont open the app, which I often forget to do , you will not remember what days you should be ready for action.
