Bests & Worsts Reviews from Amazon

Simple, straightforward app that lets you keep track not only of your visits from Aunt Flow, but those special moments, your mood and other hormonal trends (acne, eating habits and such) through out the month, gives a prediction of when your next visit will be which is fairly accurate after you have tracked with the app for a couple of months, and a guess at your fertile time. Easy to use, glad I have it.
