About this app

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

This modern natural family planning method has been researched extensively in efficacy trials. It is the only proven family planning method which allows you to manage your fertility simply by tracking your period. And CycleBeads is the only Android app 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.*

To use the CycleBeads app, you should have cycles between 26 and 32 days long**. Most women do, but not all. If you don't know if your cycle is in this range, the CycleBeads app can be used to track your cycle lengths. It will tell you if your cycles are in this range.

It’s simple! Enter the date your most recent period started.

Then, the app tells you what day of your cycle you are on, whether it is a fertile day or an infertile day, and when your fertile days will come this cycle. This information is all based on the Standard Days Method. You can use this to plan pregnancy, avoid pregnancy, or just as a period tracker.

• A calendar and a picture of CycleBeads that show you your cycle based on the start date of your period
• Customizable alerts telling 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 to track key information for yourself, or to discuss with your health provider or partner
• Ongoing cycle data history so you can see the start dates of your previous cycles, the length of each cycle, and whether that cycle was in the range for using this method effectively.

I like how simple it is to use. I really love the list where you can see your complete history so clearly, I can't find any other app that shows that. The only problem however, is that every time I change device, I have to start again as there is no backup or import option. If it had that I'd change it to 5 stars.

I have used the natural cycles app for a year and you have to take your temperature every morning which I stopped doing. It also is expensive! This app gives you enough coverage for even if you ovulate late in your cycle! My period is every 27 days like clockwork so this method is perfect for me to prevent pregnancy without all the temperature taking charting confusion ECT. Doing all of that is pointless when you have a regular 26 to 32 day period! This will work even if your period is late once

I can't change the answer to "is your period monthly". I told it that i didn't know if it was and now it's treating it like it is monthly and complaining to me that i need to try something else. It's fine for people who've tracked a bit before getting the app and who get 7day periods, but if you don't check those boxes, I'd suggest you try something else. It's good, but not for me.
