Apple Watch, meet Natural Cycles
The FDA Cleared birth control app now uses your Apple Watch temperature to help you prevent or plan pregnancy.
What is Natural Cycles?
The Natural Cycles app is a regulated medical device intended to be used to prevent or plan pregnancy. There are only 6 days each cycle you can get pregnant and the Natural Cycles app is able to use body temperature to pinpoint these days.
Way more than a cycle tracker
While tracking your cycle is helpful, period trackers should not be used to prevent pregnancy. Unlike cycle tracking apps, Natural Cycles is able to predict and confirm ovulation using body temperature.
Cyclers over 10 years
How does it work?
Natural Cycles is powered by an algorithm that can identify when you’re fertile. Wear a compatible Apple Watch with temperature sensors to bed and measure while you sleep - it’s never been easier to use natural birth control.

Even with my highly irregular cycles, this app has figure me out! It’s done what I never thought could be done. It took awhile to learn, a few cycles, but wow, I’m super impressed and will never stop using this app. I also learned a ton about my body. Highly recommend!

I only wish someone had told me about natural cycles before I went through the inferno of a copper IUD! Now I make it my aim to tell all my friends and family about NC… this should be part of sex ed… I have learned so much about my body and I feel in control of my own fertility. It’s amazing. And my period symptoms have significantly reduced from going all natural. I will be a lifelong member!!
