When calculating fertility for pregnancy with natural family planning, Cycles takes advantage of scientific research that’s more accurate than the 'rhythm method' of yesteryear and has a real-world failure rate comparable to that of condoms. Even so, this app is designed for informational purposes only and should not be used to prevent pregnancy.

You can manage subscriptions from Account in iTunes after subscribing, you’ll also be able to cancel the auto-renewing subscription from there at any time.

Love this app

I am just starting my period and this is super easy and super simple just put when you had your period then put how long and boom you are set up

This app will tell you how long your period will last and you can tell them what you are felling and what you are experiencing every day throughout your period like your cravings if your happy sad and or mad or feeling cramps back pain and heat flashes and it will even ask you what you are thinking

If it’s your first time having your period I would tell you to get this app I’m a twin and that means me and my twin sister are both going through the same thing but not at the same time I’m 1 min older then my sister which don’t mean much but I had my period first and she had here period a year after mine so I told her to get this app I told her it is super simple and easy and well is always correct which who does not want it always correct

Could be a little better

I have been using the app for several months. I do like it. It has a few features that I don’t like but do keep it for the features it does have. I don’t like that you can spin the wheel and push the middle button and it changes the whole month. It could really cause problems if you are trying to avoid getting pregnant. I also don’t like that it’s not intuitive to the days in your cycle from month to month. If your actual cycle is say 24 days long, even for a few months. It will still show the next cycle with however many days you originally manually put your cycles are (say 26 days.) so it is not intuitive and if you don’t change it manually than the “prediction” of the ovulation day is off by days.

Good - but confusing

I was hoping to use the app to track and predict my irregular cycles. The amount of information you can input is awesome- basal body temp, mucus, etc. But it doesn't automatically calculate when your next period will be based off your previous ones you've tracked. You have to input your average cycle length yourself which I find really inconvenient and can be extremely inaccurate. I have to manually count how many days it has been between all of my periods and then add the total days, then divide the total by the number of periods to get the average. It would be so much more helpful if the app did this automatically. Another odd thing is that you can change the current day on the cycle view. Beyond just going back to yesterday to put in information, you can actually change the day to today being the 21st day in your cycle vs the 20th. So again this provides the opportunity for your data to be inaccurate. Other than that, the app is great. It doesn't crash, and it has an easy to use interface.
