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.

Been using for years, private, accurate and customizable. The main issue is the updates; they don't do it often enough to keep the widget functioning, so unfortunately last month's long overdue update is now useless for this month. (4 days later) Weird how there's suddenly an update showing for 4 days before my last review when it was still showing the January update at the time of my February 8th review AND how it did absolutely nothing. 10 years and I'm going to start looking elsewhere.
