The CycleBeads app enables you to plan or prevent pregnancy easily and effectively by simply tracking your period each cycle. Just enter the date your period starts, and the app identifies your fertile and non-fertile days according to the patented Standard Days Method®.

This modern natural family planning method has been researched extensively in medical trials and is the only proven family planning method which allows you to manage your fertility simply by tracking your period. iCycleBeads is the only iPhone app in the world based on this method. It has been found to be 95% effective in perfect use and 88% effective in typical use.*

The one medical criterion for using this method effectively is that you should have cycles between 26 and 32 days long**. Most women do, but not all. If you are unsure if your cycle is in this range, the CycleBeads app can be used to track your cycle lengths and will let you know if your cycles are in this range.

You can also take a self-screener at: www.cyclebeads.com/screen

To use iCycleBeads, 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 Cycle Beads.

•A visual representations of your cycle based on the start date of your period in both calendar and CycleBeads formats
•Customizable alerts notifying you when you are on your fertile days, when your fertile window is ending, and when you are likely to start your next period
•Alerts reminding you to input your period start date or when you had a cycle outside the range of 26-32 days long
•A notes feature which allows you to track key information that you may want to discuss with your health provider

Best Alternative to birth control


I have terrible reactions to birth control and was so relieved to find this app. Cyclebeads Fertility tracking has been a great alternative. I’ve been using this app for over three years now and it’s been a simple, so far accurate way to track fertility. I have used it for birth control as well as trying to conceive and both times found it was effective and easy.

I used this method before it was an app, just the string of beads. It’s been simple and helpful and reliable. Even post-vasectomy, I continue to use it to track my cycle.
