Disclaimer: Period Tracker period and fertility forecasts may not be accurate and should not be used to prevent unwanted pregnancy. To forecast ovulation Period Tracker calculates 14 days before the projected start date of one's next period. Forecast accuracy depends on a number of factors including how regular one's cycle length is, when one actually ovulates during the cycle, and how many periods have been logged in the app. Anxiety, stress, diet, nutrition, exercise, environment, medications, age and other factors can also affect one's cycle from month to month.

2017 - still love this app!

2014 - Use the note section everyday to jot down what I had for dinner and late snack -- see how it affects my weight; what I did for exercise, etc

Great app

I've used this app for a couple years now and it's very accurate.

Good app, practical for tracking and notes. Only downfall is that it only calculates ovulation as 14 days before next cycle which isn't always the case
