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.

I have never had a normal period since coming off birth control, I could never pin point when I had my last period! Now using this app makes it a whole lost easier! Not only does it pin point when you had your last period but pin points when your due it next and has a count down! Can track when your intimate last and can help you if your trying to conceive when telling you when your most likely that month! Highly recommend has a few cool things aswell


Cannot sing the praises of this app enough!!

Such an amazing app. I've had this app since 2010 when I was 13 years old and only started my period like 8 months prior, and here I am today 20 years old and still using it lol! I haven't missed a single period log and it's so in sync with my cycle it's crazy. I always know exactly when I'm gonna be on without fail. And all the little add-ons are good too so I can keep note of a lot of things.

Just all round a really good app! Deffo download.


Great App

Wonderful app that I’ve used for years now very consistently. It’s extremely accurate (or maybe I have a very regular cycle!) and it’s come in very useful when I’ve had to give details quickly about my cycle dates to doctors. I don’t use it to its full though with noting my moods, feelings etc. I just track my period and note when I’m ovulating. I’ve now got my teenage daughter tracking her cycle using this app too. This is a great app 👍
