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 this thing for over a decade now, ha. It's never failed me. Tracks my period nearly perfectly! And it's been interesting seeing the different ways my cycle has...cycled, lol... over the years. My various stats and such. Been so faithful to this thing that it hadn't even occurred to be there's likely been other period trackers released since. And sure enough in just looking, I see there are. Ah well! PT, it continues to be. If it ain't broke....

Reliable Simple Don't Change. Been using this app probably since it's beginning on many phones. I always remember to get this app. It has been getting old, I would worry it would disappear one day but after seeing similar comments like mine, I had to leave a review. I love that they don't try to fix what isn't broken and has virtually stayed the same for decades. Maybe they fix a bug or two but the Icon and Graphics and everything looks almost exactly like same as the first time I downloaded.

I have been using this app since I got my first period and let me say...I still love it almost a decade later. I have downloaded dozens of other trackers, but always ended up deleting them because they're not as good. You can add your own symptoms, moods, and endless notes everyday for free with no intrusive ads!! I would probably never go premium, since I have all I need using the free version, but this tracker is just so user-friendly and with lovely visuals. I can't recommend it enough❤️❤️
