Enter your period for at least two consecutive cycles, and iPeriod® predicts your next expected periods, fertile days and ovulation! Each time new data is entered, statistics are updated.


The only app that truly graphically displays your data on the calendar... other apps simply place a single symbol to represent all symptoms.

• The MOST accurate: predictions are based on your cycles (not averages) and improve over time
• The MOST customization: adjustable luteal phase, hide symptoms not used by you, manage which icons appear on calendar
• The MOST personalization: 4 calendar styles, various skins
• Customizable icons to better suit your needs
• Breast exam reminders
• Searchable note history (including freeform notes, moods and symptoms)

Do not rely on iPeriod® to prevent pregnancy.

Customer Reviews


I have been using the Fertility Awareness Method for almost 10 years and was so happy to find an app I could use on my phone instead of a paper chart, but this is the RHYTHM method! FAM uses your fertility signs (cervical fluid, temperature, and symptoms) to determine your fertility on any given day. Rhythm uses past periods to determine the same thing...and it doesn't work! This app has projected my period and ovulation every month for the next 2 years! Dozens of different things EVERY SINGLE DAY can affect your cycle and even if your body is like clockwork it will never be exactly the same! For example, after a death in the family and a sudden trip across country this last month I ovulated late instead of when I typically do - right in the middle of everything - and so hence, my period will arrive a little late. The app has been giving me notifications for the last three weeks like, "You are ovulating!" "Your period is expected in __ days!" and today: "WARNING!!: Your period is 1 day late!" Even if I wasn't expecting a later period it's not always going to arrive on exactly the same day and I feel bad for the woman who has never used either method before that is going to freak out because she thinks she might be pregnant or gets pregnant by mistake. So as I already stated, USE WITH CAUTION! It is easy to use but I have deleted it and felt the need to share.

Love it but i could still love it more!!

I love this app it helps me so much. I just got married and we don't want children yet. This app helps me make sure accidents don't happen and if an accident does happen i dont have to stress wondering if im late i know. Things i would like added to the app would be the ability to hook it up to my email for example i just got a new phone and downloaded the app i had already been using it for 3 months and by switching phones i had lost all of my data and had to start all over also i would like to be able to recieve an actual alert on my phone when my period is expected not just an alert once i enter the app or once my pd comes on. Other than that this app is great and has really made my life so much simpler. Thank you iperiod!!

iPeriod is a great tool for personal organization

I've been using iPeriod for over a yer and enjoy the ability to track my period, intimacy, fertility in one place. I also enjoy it being on my phone instead of on a computer. I like lots of people use computers for work and don't want to look at one at home so it helps to be able to use this app at any time day or night.

I just started reading the forum also and was happy to see such a variety of topics from fertility to science.

iPeriod is one of the apps I use regularly so when the recommendation came to update this app I gladly did so and then updated all my apps so its Ben helping w my iPhone usage! I didn't notice any crashing problems.
