Natural Cycles is more than a period tracker. Most other fertility tracking apps assume your cycle is 28 days long, even though 87% of women have cycle lengths that don't fit into the 28 day pattern... We understand that birth control is not a one-size-fits-all. Your cycle is unique to you! Our algorithm uses personalized temperature data to confirm your ovulation, reducing the risk of you being assigned an incorrect fertile day. Unlike period trackers, the NC° app allows you to identify your fertility status daily, so you can prevent pregnancy or plan for it with greater precision.
From contraception to planning pregnancy and every cycle in between – Natural Cycles is there for you with each stage of your fertility journey. Still not sure? Download the app and test out our Demo Mode. The app supports syncing with Apple Health.

Ratings and Reviews
Editors’ Notes
Understanding the complexities of ovulation cycles is hard enough. Thankfully, Natural Cycles aims to make the monitoring process a whole lot less stressful. By logging just a few vital signs, the app’s powerful algorithm can help predict crucial fertility windows, pregnancy, or even potential miscarriages. We’re also impressed by Natural Cycles’ clear, intuitive design—no cold waiting rooms to be found here.
Worth the effort!
I used to be on a pill for many many years and once I stopped taking the hormones after getting married, I have realised what an angry person I was because of the pill. Add the weight management problems to it and I’ve promised myself to ditch the pill forever. I’ve made a bit of research and came across Natural Cycles. Since I’m a very diligent person, I decided to give it a try. The verdict? Amazing! Firstly, the output data is very good, you get a deep insight into your cycle and your body. And the data is accurate - it predicts the period, the ovulation very well. Secondly, I like how it encourages you (or not, depending on whether you plan the pregnancy or try to avoid) to give it a go. I used the app for half a year to prevent pregnancy and then to fall pregnant. And we managed to conceive on the first attempt! The app follows your pregnancy and give you some info on the progress, like the foetus size, what is happening at the moment, etc. Now My cycle has returned to normal after one year of giving birth (thanks for breastfeeding) and I’m very happy to return to NC in a prevent pregnancy mode. I admit, measuring the temperature is a bit of pain in the tooshie and I wish NC came up with the bracelet to wear during the night, which measures your temperature at the scheduled time (like Ava). But still, I would never go back to the hormones! Can fully recommend the app for women who want to prevent pregnancy and who plan it!
Everyone is different
I have been using this app for almost 2 years now to prevent pregnancy, i have even recommended this to friends and whilst I have come across complaints and issues from others re using this app and the thermometer - I have never experienced an issue or “scare” This app and the product itself is very much about putting the power and responsibility in YOUR hands- many women who complain to me that its always red, or fell pregnant or dont trust it etc need to understand that you get as much out as you put in. Yes you have to be responsible and use protection or abstain during red days ESP at the start , yes you have to be strict with taking temperature and develop a routine that works for you even when you travel (i travel a lot) and yes you have to look into the apps statistics to educate and inform yourself on how your unique body runs. All these things lead to a perfect combination of self responsibility and technology to aid you in preventing pregnancy and learning more about your body. Ive been told by nurses (when they ask me what contraception im on) that this isnt wise and isnt safe and bla bla bla and to me what isn't wise or safe is being pumped full of hormones and Chemicals you have no idea how that affects your mind body and soul. So in summary Yes this app works a treat for me but with great power comes great responsibility and you have to own it or this app will not work for you!
