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. The app supports syncing with Apple Health.

I’ve been using the app for over three and half years now once I decided to take control of my health and stop using hormones to control my erratic cycle. I don’t even remember how I found out about it, but I loved the story behind how it came about and that it was backed by science. I initially struggled with the app results because I had a highly irregular cycle (from my teen years til into my mid thirties) which generally gave me minimal green days, which was frustrating. However, I changed my lifestyle (my diet) two years ago which lead to my cycle normalising, and now I regularly see 70% green days per cycle. I’ve considered going back to other simpler apps, but there is something comforting about natural cycles, which has only improved again and again over the years with the additions to the app. Would love to see them create a widget in future that allows us to enter the temp without opening the entire app, and the option to change the background colour on the main info page. The ‘month’ tab can also be a little daunting to absorb as its a lot of colour coding in one go, would be nice to see a more traditional style calendar layout with smaller colours used.But I do genuinely love the messages and reminders that turn up in the app, the cycle summary I get every month and just hire simple the entire process is. I highly recommend this to anyone who is ready to start listening to their body and take control of their health.
Amazing Natural Contraception!

I made the decision to come off birth control in March 2021 due to suffering extreme pains and extremely heavy bleeding which would often send me to hospital. I had been on the pill since I was 13 (10 years) and would skip my period due to the fear I had developed. The mental side affects were also a big issue for me and I tried many variations, even the implant which made it worse. Along came Natural Cycles! I will never go back to any other contraceptive. This has changed my life and after one cycle using this method, my cycle returned and has been regular ever since! (Of course this may not happen as quick as it did for me as we are all unique) The app provides you green days for when you’re safe and red days for the days you need to be careful. It gives you insights about your cycle, handy tips and lots of information which has helped me so much! I am now using the app to plan my pregnancy so that natural cycles will continue to help me along my journey! I have learnt so much about myself and my body and urge anyone considering trying this to 100% sign up now - it will change your life for the better.
Contraception of the future!

I have tried every contraception, all different kinds of the pill as well as implanon, mirena, nuva ring... everything but the injection. Hormonal contraception turns me into a different person, it affects my moods so badly and I feel after being on the pill for so many years and changing so often that I had just decided I was a moody person when in reality it was probably what I was putting into my body. I’m loving the natural cycles app, I think every female should have this to help learn how their own body works! I’m never going back to hormonal contraceptives. I’ve been waiting for something like this forever. This is the contraceptive of the future BUT just like everything, I think you need to read up on how it works and whether or not it works for you and your lifestyle. I do think you need to be mature enough to be prepared if it fails, in a healthy long term relationship and need to be open and discuss how it works with your partner. Works great for me and I love it!!
