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.

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!!!! 👍👍👏👏🥇🤗😊

Reliable, affordable


I've had this app for about 5 years. Its assisted me to chart an irregular cycle, keep notes for reference on losses and kept me informed on my current pregnancy which is going to term! I always recommend this app to anyone of childbearing age because you can keep track of when you spot, your period begins, your period ends, how long your cycle is, when you ovulate and any symptoms you have. It also charts your weight, how many steps you take and even some details of lovemaking (for TTC, of course 😎) It has both an absence mode, TTC mode and pregnancy mode. Pregnancy mode has been helpful because it provides an estimated due date, a countdown on how far along you are and a weekly update on where you're at in the pregnancy.
Another thing I love about it is that, although its a little less fancy than apps like, The Bump, its not full of ads or articles pushing products.
One improvement could be a photo album to track your bump weekly and a baby registry checklist and hospital packing check list which is why I only gave it 4 stars. Overall a great app and worth paying for!

Love it.


2018 update: still loving the app! So on point that I don’t have to worry. I love the notifications. I love the fact that I can plan ahead for doctor’s appointments and vacations simply because the app is accurate. Keep doing what you are doing Period Tracker!!!! As much as I don’t like my time of the month, I absolutely ❤️ you!!!

2017 update: Four years later and I still love it!!! As I've aged and my period has started to change, it has helped in keeping track of the fluctuations so that my gyno and I can keep an accurate track of the change. Hopefully we can figure out what is going on. Thank you Period Tracker App for being my reliable source of information. I tell everyone about you! I coach young girls and tell their parents about your app so that they can track their daughter's there's a new wave of frackers headed your way! :)

2013: I have been using this app for three years. The only thing I wish is that it could monitor for more than 1 person. I have to use another app to track my daughter's period.
