Period Tracker App for IOS and Android Smartphones 

The CycleBeads™ smartphone app enables you to use the Standard Days Method® of family planning through your iPhone, iPod Touch, iPad or Android phone. This is the only smartphone app in the world based on this highly effective, well researched family planning method. It's more than just a period tracker app, CycleBeads lets you plan or prevent pregnancy easily and effectively with your mobile device!

CycleBeads® Apps are available
worldwide in the iTunes and Play Stores.

To use the CycleBeads app, simply input the date your most recent period started. The app immediately lets you know what day of your cycle you are on, whether it is a potentially fertile day or an infertile day, and when your fertile days will occur this cycle, all based on the Standard Days Method. You can use this information to either plan pregnancy, avoid pregnancy, or just to track. This information is provided in both a calendar format and in a visual representation of CycleBeads.

How to Use the CycleBeads® Smartphone App to Plan or Prevent Pregnancy

To use the CycleBeads smartphone app, enter the start date of your most recent period into the app. At the tap of a button, this period tracking tool shows you where you are in your cycle and whether you are on day when pregnancy is likely or not. The information is displayed by a virtual representation of CycleBeads® and on a calendar view. You can use this information to plan pregnancy or to avoid pregnancy.


As a CycleBeads user, you will receive alerts letting you know when you are on a fertile day or non-fertile day and when you are about to get your next period. You will also receive a period reminder to enter your next period-start date, if you forget, and a warning notice if you have a cycle that is outside the range for using this scientifically based family planning method.

Who Can Use CycleBeads® Smartphone Apps for Family Planning?

Anyone with an iPhone, iPad, iPod Touch, or Android device can download the CycleBeads smartphone app. The method is most effective for women with menstrual cycles between 26 and 32 days long (allowing for one cycle in a year outside this range). CycleBeads cycle-tracking app will help you determine if your cycles are in the range and whether they stay in this range . Women with cycles outside this range should use a different method of family planning to prevent pregnancy.
