I am probably not the typical user - when I first started using this app, I was perimenopausal and tracked my often irregular cycles plus I renamed the special icons to track our intimate life. Fun looking back! Every time a doc asked me when my last cycle was, I pull this up and get the answer quickly. Had a friend see my usage and got it for her daughter, newly having periods and accidents at school- now the daughter knows when her period is almost here so she can be prepared. Highly recommend, whatever your need!
