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 birth control 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. *E.

Wonderful
This app has been able to help me keep track of cycles and 2 pregnancies. I love this app and it has been so helpful!
Don’t recommend the thermometer
Thermometer constantly struggles to connect. Sometimes it takes me ten minutes to try to get the thing to connect. Only get this app if you have the watch or the ring, else don’t waste your money on this “special” Bluetooth thermometer that only sometimes connects.
Changed the way I look at my health!
This is by far the greatest thing I’ve ever done for myself! I was super nervous about starting Natural Cycles, but after I started it, I realized there was so much more to this app than it being a hormone free birth control! I feel like I learned way more about my body using this app than I have since middle school. I also started thinking more about what lifestyle choices I wanted to keep and change and I kid you not, I have already had my very first successful cycle just by using this app. And I just started it about a month and a half ago! I couldn’t be happier with how I feel and knowing I am now in control of my body, instead of extra hormones taking over. 10/10 love this app! (The thermometer is probably the best/most interesting thing I’ve ever used as well!)
Life changer.
Getting off hormonal birth control changed my life for the better. I had significantly less anxiety & depression, I've learned so much about my body, my mental fog lifted. I felt all around so much better. I have a piece of mind that I’m not destroying my fertility with synthetic hormones anymore! Truly, thank you NC for making it easy. (with an apple watch) 😊
I’d like More options to add
Personally I’d like to be able to add food exercise water and possibly weight. I want to se show my diet affects my cycle
10/10 would recommend
NC has completely changed my life. not only has it given me the education my physicians have failed to do over the past 27 years, but the confidence needed to take control of my reproductive health on my own and with my partner!
Learning about myself!
I love this only two months so far and I’ve already learned so much about myself. I feel like it all makes sense now. I can clearly see the patterns and correlation between phases and moods/symptoms. It’s helped me be kind and patient to myself during those few days prior to my period where I feel crummy. I’m a Natural cycles for lifer!
Cycle smoother than ever with this updated version of the app!
