The iCycleBeads Lite 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 Lite and the full iCycleBeads app are the only iPhone apps in the world based on this scientifically tested method. It has been found to be 95% effective in perfect use and 88% effective in typical use.*

The one medical criterion for using the iCycleBeads apps 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 iCycleBeads app can be used to track your cycle lengths and will let you know if your cycles are in this range.

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

Knowledge is power!


CycleBeads is a great tool to help me know where I am in my cycle, when I should expect my period, and now when are the days in most likely to get pregnant. When my doctor next asks the first day of my last period, I'll be able to answer confidently, and not "some time around the....". Having the information easily accessible on my phone is so convenient. I can see the advantages of the "full app" so that I can see my cycle over time, and will likely invest in that in the future.

L&D nurse approved


So excited about this app. I'm a labor and delivery trained nurse and Cycle Beads gets it right. Tracking your cycle over time is so helpful in making the right choices regarding fertility. This app is user friendly and so streamlined that as a healthcare professional I would say it is close to foolproof.

Great tool!

Keepin it real.

So far it's working wonderful! It's awesome not to have to guess. Cycle beads makes that so much easier! My husband and I don't have to try and remember what day it is in my cycle, we can just check the app. It's an awesome app for marrieds!
