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.

○ No method of birth control is 100% effective. Even when using the birth control app perfectly, there is still a chance of getting pregnant.

I’ve wanted to join the community and use this app for about four months now, but can’t sign up, opt into their sales or reach them via their website/email. It’s been very frustrating as I’ve really been wanting to try their product and app 😔

4 months and I’m loving it!

I feel so much more in control of my contraception choices, and have much greater insight into the idiosyncrasies of my body/cycle since using this app. Plus, it’s been great motivation to finally start going to bed and waking up at a consistent time every day!

Natural!

MacMcCSA on

Best decision I made! Love that I’m not using any pills!

At last

Vicbirds on

An option for those of us who hate putting external hormones into our bodies but also hate condoms! I have two young children already and we're not sure if we are finished having kids or not, so other forms of contraception are also not ideal right now. So glad to have found this app!

Trying to get pregnant

Really helps keep track of my ovulation cycles!

Amazing app

Ashleywarnerrrrr on

I recently came off my oral contraceptive and this app has helped me and my fiancé so much! It's a natural contraceptive for us and tells us when to be careful during the month. In a few months from now after the wedding we will switch the app to the option where we want to have a baby, and it makes it so much easier by telling you when you're ovulating and when you're most fertile. Also guides you by suggesting when to take an ovulation test. I'm so sure this app will help us bring our first baba into this world. I highly recommend this app

Highly recommended

Luke DW on

This app is incredible! It's nice to be able to see what's happening with my Fiancée cycle. It's good to know how we should plan for weekends away, or when to be more careful. I love getting to know her better according to her cycle. Would recommend this to anyone who wants a natural solution to birth control. Happy to have this app replace the pill.
