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.

Brilliant app

This app is brilliant. I have never had my time of the month on a regular basis. However, this app has managed to workout my cycle. Even after effecting my period with birth control, which now causes me to only have aunt flow every few months.
It has only predicted the exact date twice. But just alerting me, of when not to where white jeans around the time is good enough for me.
This app has allowed me to recognise my bodies signs of when I am ovulating just in case I want to extend my family, as I have difficulty in that area also. It definitely makes it easier to plan dates with my partner around duvet and chocolate days.
I would definitely recommend this app to those who have irregular periods like me.

I love this app , especially if all your settings are set correctly , I fell pregnant and i went of the estimated date on how many weeks pregnant I was that period tracker predicted , then I had my 12 weeks scan a week late at 13 weeks pregnant (as period tracker said I was 13 weeks pregnant ) and I was bang on 13 weeks pregnant , it's amazing I also love the weekly updates with images on your babies progress With some really good infomation , sadly I went in to premature labour and had my little boy at 16 weeks , how ever period tracker logs everything and I have all the days I was pregnant for saved throgh out the 4 months which is special it's like a little keep sake , there for I love this app

Excellent even helped my Gynae Consultant!!

Excellent app does everything it says and easily and well. At a recent Gynae appointment I mentioned it to my consultant who immediately asked if I could get the data to him which I was able to do in minutes and at my next appointment he asked for its details so that he could get other patients to use it as the information it contained was helpful. Great app u just have to remember to note all in it but its worth it.
