Natural Cycles places birth control into your own hands.

Founded by particle physicist, Dr. Elina Berglund, with a goal to offer women an effective, hormone-free method of birth control, Natural Cycles identifies ovulation by analyzing basal body temperature, learning your unique cycle so you can get to know your body better, and know the exact days you can and can't get pregnant.

Natural Cycles is a clinically-proven birth control option alongside the pill, IUD and the condom. 93% effective with typical use, and 98% effective with perfect use. The clinical study that determined Natural Cycles' effectiveness is one of the largest of its kind, with 15,000 women and 600,000 menstrual cycles. It was peer reviewed and published in the renowned journal Contraception.*

The app supports syncing with Apple Health.

○ Yearly Plan (Recommended): $89.99/year.
○ Monthly Plan: $9.99/month.
○ A subscription is needed to use the app, and while a free demo is available, we recommend a minimum of 2-3 cycles for Natural Cycles to be most effective.

I was tired of using the pill or nuvaring but still wanted to have some control, know myself/my body a little better also. A friend of mine talked to me about this app and I’ve been using it for a few months now and I’m not pregnant so... I’m very satisfied 😃👌

Annie-Clara ,

Do not use as contraception!

This method probably only works as contraception when you have a very regular schedule and period, don’t travel too much (definitely not to different time zones) and measure every single morning.

I was dumb enough to trust this app and ended up pregnant right when I renewed my subscription.
They also don’t do refunds btw!

So if you really do not want to get pregnant, use a trusted method that’s been advised by your doctor! And not this

There are a lot of cases where women fell pregnant while on prevention mode, you can give it a google

A must!

This app has taught me a lot about my body. I have learned so much about my own cycle -- the cycle all women go through every single month. I think this app must be introduced at schools since the first day a girl gets her period and hopefully boys could take part in understanding how this cycle works. It should be taught as a compassionate journey of shared responsability.

This app should be something women should be able to share with her significant other.

Technology could set women free of all those hormonal methods of contraception that only take us away from embracing our own natural cycle.

It was about time for an app like this!
