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.

The widget is no longer accurate, despite the app being up to date. The widget ALWAYS shows either, 30 days left, or day 1 of cycle. When I click on it and it takes me to the home page of the app, everything is accurate. So it's just the widget that's the problem. Unfortunately I use the widget as a quick reference to monitor when my cycles are going to start, how many days left, etc. and I don't always like having to open the app just to close it again a few seconds later. Please fix!

every time you open the app you get a pop-up for a free magazine, no matter how many times you decline it still pops up. every time. and I just found out, after upgrading my phone, that it doesnt automatically back up your data so ive lost over a year of data. so many features are locked behind a paywall, finally decided it's time for a different app

rarely accurate ... I've been using this app for years and it maybe once or twice was accurate. as far as when my cycle started. I switched to another app flo for the past year that app is way better and a lot more accurate. I wait a year just to see if anything would change but nope p tracker still is inaccurate. I mean it does get a ballpark range but rarely is it accurate? a day or two off is fine but this app will be a week off for me. where's the flo app it's either right on or a day off.
