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.

100% worth it

I downloaded Period tracker because I knew I couldn’t keep track of my period myself and this app has never failed me. It is completely free but if you want the premium version then it is $15 a month so I just use the free version and it is amazing. This app has calendar which shows you when your period is expected to start and when it is supposed to end. You can also keep track of your moods and symptoms such as cramps, bloating, nausea, spotting and much more. You can also follow friends on Period tracker and complete challenges like 7 days of no phone before bed or 7 days of water before meals. Period tracker has workout on it too. I 100% recommend downloading period tracker.

I’ve used this app for years and find it handy. Even if your cycle isn’t like clockwork at least it can give you an idea of where you’re at. One improvement suggestion- rather than use only the last three periods to work our cycle length please use ALL recorded cycles. One of the first questions a midwife / dr asks when you get pregnant is how long is your cycle? This helps determine due date. Three entries is not enough data for an average of any type. This causes mine to swing wildly and doesn’t give me an average at all. I think a lot of improvements could be made to the look and layout of the app too, it feels a bit old and clunky, but still five stars as it’s a free app and it’s useful to me.


Simple and effective app

This app is handy for tracking the date and duration of your period as well as giving you the ability to add in relevant notes each day (e.g. hormonal changes, moods etc). It will calculate days between your cycle and project the date of your next cycle. When you’re trying to conceive it’s helpful as you can see when your fertile window is. And once pregnant, switch your setting over and get an info-packed, week by week pregnancy guide, due date information and more!
