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.

Great app, customizable, helpful-trip planning!

Not Really A Fan Of iTunes

I originally downloaded this app because I wanted to track certain behaviors with relation to my cycle. Specifically, back pains and those days I just got so frustrated. Sure enough, they were usually a few days before my cycle. What I love about this app is how customizable it is. It has a variety of little icons and pictures, and you can track anything you want from chocolate cravings to headaches. I used a little picture of a whale to track when I started feeling bloated. I just noticed they have a little corked wine bottle with incrementally more bubbles in it to represent constipation. How could you not love that?

I have since had an ablation (procedure for those done with childbirth with extremely heavy periods, it scars uterus lining so it doesn't build up so heavy) and now have my period much less frequently. The app has successfully mapped my new, longer cycle with accuracy. I imagine this app would be extremely useful to someone trying to conceive, or just track their fertility. I also use it to check ahead and see whether any future vacations or work functions will be impacted. Whether I need to pack anything, etc.

An Amazing Moontime Cycle Log!!

x jeannete x

I love this app so much!!! I have been using this app for so many years. I love how it keeps my Moontime cycle logged, organized and charted providing an easy read and analysis of my cycle. I love how one is able to also log symptoms associated with their cycle with just the push of s button— there are preset symptoms listed, and you can also customize your own (ie. breast tenderness, cramps, etc.) I appreciate how it indicates ovulation time, and your Moon’s next expected date of arrival. It helps so much when I am trying to prepare for the month or if I’m feeling something — I can confirm that I’m ovulating. There are so many other great things about this app that you must explore for yourself. I am extremely happy with it, and I am so thankful that it was created. It’s so easy to use (literally just a click), and it has helped me tremendously with regards to keeping track of my cycle and symptoms over the past few years. I’ve actually learned a lot about my process because of this. It’s a beautiful app. I would definitely recommend that you get it if you are in need of a Moon Cycle log. Thank you and have a beautiful day!

Thank you


I'm an inconsistent person at best, but I am consistent with this app. These days, everyone keeps their phone with them, so it's easy to remember to log in and track your period. For me, it was an early warning that I had endometriosis. My periods were irregular, and I experienced an abnormal amount of pain during my cycle. Menstrual cycles for most women operate like clockwork and are relatively painless. I hope that the knowledge regarding what women with endometriosis suffer from grows, so that more of us can learn about the diagnosis before it's too late. Thanks to the Period Tracker team for giving me an opportunity to better track my cycle so that I could see there was a pre-existing problem I knew nothing about! Maybe your app could also encourage more awareness regarding health related topics in regards to a woman's cycle for reasons just like mine. With knowledge comes power, and thus, greater responsibility. Let's help our fellow women!!!
