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.

PRICING PLANS:
○ Annual subscription (and FREE NC° Thermometer): $99.99/year
○ Monthly subscription: $13.99/month
○ We recommend a minimum of 2-3 cycles to get the most out of your Natural Cycles subscription.
○ Our subscription fee helps to protect you and your data. Many free apps work by selling their users’ data to third parties for advertising. Privacy is non-negotiable for us; we will never sell your data.
PRECAUTIONS:
○ Natural Cycles does not protect against sexually transmitted infections (STIs). Use a condom to protect against STIs.
○ No method of birth control is 100% effective. Even when using the birth control app perfectly, there is still a chance of getting pregnant.
○ Natural Cycles is for women over the age of 18.
○ Natural Cycles is available as a method of birth control in the US, Europe, Canada, Australia and Singapore. In countries outside the US, Europe, Canada, Australia and Singapore, Natural Cycles is intended to be used for fertility monitoring.
○ To use Natural Cycles, you need to understand English or one of the supported languages.

This should be required for every health class
I feel like an idiot that I didn’t understand my own body and cycles like I do now that I have this app. Where was this when I was going through puberty! I feel emboldened, confident, involved and in control! Plus I get to feel like a biologist every day!! I love logging my data and getting the results. Just get the app already. It’s a no brainer. Oh and the company is really good to deal with, they forgot to include my thermometer with the test strips, I let them know and they sent me one right away, no questions asked. Simple! Five stars all around. Bravo!
Good App
Good app!
A Dashboard of Your Body
Love the depth of knowledge and control of my reproductive side. Safe. Smart. Full of integrity. Can’t imagine life without this app anymore! 3 years and counting...
An app for every empowered female!
Packed with so much information to self-educate on our own cycles. Really allows us to take the power back and be in full control and awareness of the cyclical beings we are!
Great app
Great app it gives me confidence in monitoring my individual cycle and stay natural without the need for hormonal drugs as contraception. Only wish it was a little cheaper or if it charged monthly perhaps.
Game changer! I feel empowered and out of the dark
I had just read up on this birth control method but am not wired to have a graph on my wall and remember these things. I love it and really think it’s worth paying for, takes the guessing out of it and most importantly (for me) it’s natural and I can understand what’s happening in my body.
Super informative and empowering
Love the app and concept. Only downfall is the beeping thermometer in the morning (wakes up the man and the dog!) Also quite expensive, but worth it (for me personally) as it’s a reliable and natural alternative.
Happy is an understatement
💡Science (in your body) is a powerful thing to learn and understand. Suits me really well as my partner and I don’t like the fundamentals of things like the pill (such as ticking your body into thinking you’re pregnant) or condoms which taint intimacy. Through some decent education this app provides, I get to know my body and enjoy the benefits. Love your work Natural Cycles!
Love this app!
I have totally taken control of my cycle and I loooove learning all about it. I study all the info it gives me! It feels so good knowing what us going on with my body. Just wish you could enter the data with no internet and then it can give you the answer when its connected, app basically doesn’t work when you have no internet. Would recommend to everyone!
