## What is iCycleBeads Period & Ovulation?

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®. 

RESEARCH
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.*

CRITERIA FOR 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 

HOW TO USE
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.  

KEY FEATURES:
•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
•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.

### 5/5 — Just got the App

*2023-10-02*

I just bought this app, how does it work. What does the colors mean?

### 1/5 — The worst

*2021-10-09*

Lost my data after years of use. Don’t recommend

### 5/5 — Love this tracker

*2021-02-14*

So easy to follow, give you reminders of when your cycle is about begin, fertile and non fertile windows. On point every time.

### 5/5 — This is the best app I have ever used.

*2020-02-23*

It’s so easy and simple to use

### 2/5 — Data Lost

*2019-10-28*

I’ve been using this app since 2013. I really only used it to help me remember when to expect my period, which was helpful. (I used a different method when my husband and I wanted to get pregnant.) I continued to use the app throughout my pregnancy to keep notes about different milestones of my pregnancy. Of course, I didn’t enter a new cycle date until after my baby was born. When my cycle returned, I entered that new date (about a year after my last cycle) and ALL my previous data disappeared. This had never happened before when I entered new cycles. When I emailed customer support, they said that unless I downloaded reports, there was no way to see previous data. I had used this app for FIVE years and never downloaded reports and could ALWAYS see my previous data. And now when I want to look back at my notes to record some things in my daughter’s baby book, I can’t because for some reason, the app just decided to delete everything. Obviously there was some glitch, yet I’m not thrilled that the “development team” can’t do anything to recover my lost data, apparently. I won’t be using CycleBeads anymore.

**Developer response:** We are sorry that this happened and are looking into it to ensure it won't happen to others. We do not collect personal information from our users which is why we are unable to restore your cycle history. While this is a benefit in terms of privacy, it unfortunately means we don't have your data. Please know that CycleBeads will continue to give you accurate information going forward as long as your cycles have returned to their regular range. 5 years is a long time! We hope you'll stick with us!

### 5/5 — The OG fertility tracker

*2019-09-30*

I’ve been using this app for YEARS and the cycle “bead on a string” method even before that. The app is simple and straight forward. I like that there isn’t a whole bunch of other “filler” junk I would never use like other apps have. 

A few things that might make this app better:
1) Instructions on how the cycle bead method actually works and the research behind it. It seems some of the other one star reviews are because they don’t understand how the method works.
2) Updated graphics or the option to change color schemes. While I love the simplicity and reliability of this app, it does look a bit dated.

**Developer response:** Thank you! This is helpful feedback.

### 5/5 — Incredibly accurate app

*2019-05-09*

This app is great and incredibly accurate. I thoroughly recommend it.

### 4/5 — Good but not for short cycles

*2018-11-21*

I like the app because it gives me a range, but because my cycle is shorter (just under the 26 days this app holds as a minimum) it recommends using another app. I wish I had known that going in! (Perhaps it was advertised but I missed it.) other than that it’s useful for keeping track!

**Developer response:** Thank you for your feedback. CycleBeads is based on the Standard Days Method of family planning. This method works optimally for people with cycle lengths in a range of 26 to 32 days.  This is a majority of women, but everyone.  If your cycles are shorter than 26 days, we do not recommend you rely on it for preventing pregnancy, but it would still be an excellent tool when planning pregnancy. If you have questions, please email us at info@cyclebeads.com.

### 5/5 — Best app!! 💝

*2018-11-14*

I have been using this app for almost 8 years now. I don’t know how much I paid for it, but it’s worth whatever it costs! It is simple to use and keep up with and is not obtrusive or annoying. And most importantly: it works!!! I have used the app to help us have a baby and also to help avoid pregnancy. I love this app and will continue to use and recommend it! Great big THANKS to the developers! 🏆

**Developer response:** Thank you for your feedback! We really appreciate knowing how CycleBeads-users are satisfied with the app and the method.  We have known that people like the CycleBeads app and use it for a long time, but 8 years --  You may be a record holder!

### 1/5 — More basic than...

*2018-09-15*

using your fingers to count and significantly more complex. Total waste of money. Carving your cycle into a stone tablet is more current than this app.
