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. RESEARCHThis 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. CRITERIA FOR USEThe 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. You can also take a self-screener at: www.cyclebeads.com/screenHOW TO USETo 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.
