Used for at least 6-7 years.
I love this app. It is a great way to easily keep track of my charts, and now with kids (that we planned with this app) the reminders are even more helpful than before! I have used FAM for 8 years and it has worked both to prevent and achieve pregnancy and this app has been so helpful for many of those years!
