I love the way the tracker takes care of everything for you. Enter your start date and how long your cycle is and it, takes care of the rest.
However, it needs minor fixes. I accidentally hit the flower on the center and it started the period. Hit it again to attempt to erase it, ended it for me. Huh? Im trying to delete the data and I had to delete and reinstall the app. Now I have to input all my data again
