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.

Love the app and it's accuracy, but as long as I've had it (at least 8 years and on 3 different devices) it has NEVER sent me a notification. That was the reason I moved to this app. My old app stopped alerting me and I was referred this one. I've only kept it because I've been too lazy to look for another app that was as accurate (and free) as this one is, but I'm finally over it. I've left similar reviews and have emailed with them before, but the notifications never come. On to a new app!

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
