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.

Tracks much more than just a cycle...


I appreciate P Tracker because it gives me a comprehensive review of past menstrual cycles, and the ability to properly plan ahead for trips and events. I no longer pack or prepare for a trip/event without first glancing ahead at my cycle, which is predicted based on past cycles. I work as a nurse, and encourage all women and girls to keep track of their cycle by using this app.. One can use this app for a snapshot of their overall health, or simply to predict their next start date.
No longer am I fumbling through a calendar counting back, or guessing the first day of my last cycle to provide information. As women, we are properly asked about our cycle at every doctor, dental, and procedure appointment, and this app makes providing that information accurate and efficient. It provides start and stop dates, as well as symptoms; which help keep track of the health of our bodies.
It compiles data entered to show patterns in physical and emotional symptoms prior to, during, and after each cycle. This is a tool that should be taught to women, to help improve the health of all women.
It does so much more than keep track of a menstrual cycle, it also keeps track of other signs and symptoms; frequent headaches, changes in beast health, skin health, emotional and mental health.

This app is a life saver!


Ok, so in the past I haven't been the best at keeping up with my period. I wld get busy and forget to mark it on a calendar and wld be left guessing my next start date. I deal with extreme fatigue, depression along with other physical pain due to PMS. Now, with this app, when I start feeling like crap I can pull it up and see wether or not something is wrong or if it's just PMS. I LOVE LOVE LOVE The period countdown in the main screen. I can even use it to plan around that week before! That way I won't make big plans during my normally horrible week of PMS!! I always have my phone nearby and this app so easy to use! If I'm in a rush I can just click the app, tap the "just started period" and it's logged. If I want to go back later and log all of the symptoms (cramps, backaches, fatigue, hurting!!...yes you know what I mean!! ) it's easy to do. It also helps me track the changing symptoms as I age. I'm 45 now, and my body is definitely changing. This helps me keep a record. Not
Just for me, but for my doctors.
For you wanting to have more kids you track ovulation and so on. It's so much more that just a period tracker. It's been a life saver for me!! Thank you to developers of
This app!!!! 👍👍👏👏🥇🤗😊

A must-have app for those with PCOS


I've been using this app since 2013 and it has done more than just track my cycle. It has helped me understand my body and what it is telling me. As someone with PCOS and a heretofore irregular cycle, I thought that this app wouldn't be particularly useful for me, especially at predicting when Aunt Flo would show. What I found when I began tracking my cycle and taking detailed notes was that it gave me all the info I needed to identify ways to improve not only my gynecological issues, but my overall health as well. This app has so many ways to make logging this info quick, easy and, dare I say, fun to do. I find that the customizable icons for symptoms and moods are especially useful for adding PCOS-specific symptoms. With several lifestyle adjustments based on what I learned about my body and cycle by tracking with this app, I went from going several months at a time without a period to having a regular, predictable cycle. Well worth the small investment I made four years ago.
