Enter your period for at least two consecutive cycles, and iPeriod® calculates your average duration, cycle length and estimates the dates of 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, 28 skins
• Customizable icons to better suit your needs
• Breast exam reminders
• Searchable note history (including freeform notes, moods and symptoms)
• Email alerts

Do not rely on iPeriod® to prevent pregnancy.

Best period app

I love this app! The graphics and color are wonderful. You can pick your own skin color for the app. I like the labeling and the accuracy. I just wish that I can transfer all my data to my new phone! I should be able to log onto any device with my email and get all of my history!!!!!! Therefore losing a star... I don't mind the ads because it's a free app. I love that I can keep track of my love connection and write notes. Also you can tailor notifications for fertile week and period week. I've looked through all the other period apps and the configuration is so weird. This is the best one! PLEASE KEEP THE HISTORY so I can continue to use this great app!

Only for 1 year, then it overlaps

I agree with the comments about the new video ads being indiscreet and ridiculous. However, my bigger complaint is I have been using this free version for a year now and when I came to a new month, there was data already logged (i.e., it wrapped around and is showing data from last year — making it completely useless any more). I submitted a question/request for advice and never got a reply. So I hope you don’t want to have customer service. Also, it is $1.99 to download your data ONE TIME. The same price to buy the full version.


Horrible ads that you can't mute. Do not use in public if that matters to you.


Turn on airplane mode before opening the app and no ads will run. If you are worried about missing a call in the two minutes you are in the app, instead simply go into your settings and turn off just the Wi-Fi and data and your calls will still come through. I have tested this and it's great!

This will work for all apps that don't require an active connection to use!

I do not mind supporting an app or website when they use good judgement in selecting and presenting ads. When the ads are intrusive, annoying, irrelevant and excessive I draw the line. Worse is when the ads cause the app to work improperly, or cause it to crash.
