Description

Natural Cycles helps you keep track of your ovulation, period and fertility. The app will show you when to use protection to effectively prevent a pregnancy. It is clinically tested to be 99.5% effective*.

*Natural Cycles has a method failure Pearl Index of 0.5, which means that 5 women out of 1000 get pregnant during one year due to a falsely attributed green day. Natural Cycles has a typical-use Pearl Index of 7.0, which means that in total 7 women out of 100 get pregnant during one year due to all possible reasons (e.g. having unprotected sex on red days, failure of the contraceptive method used on red days).

Natural Cycles analyses your temperature, period and ovulation to calculate when you are fertile and should use birth control (e.g. condoms). Our algorithm is the brains behind the app. It takes care of all the complex calculations and tells you everything you need to know about your cycle.

How it works:

Measure your temperature first thing in the morning before you get out of bed. You will need a two decimal basal thermometer to do so. Enter your measurement and other data such as period, sex and LH test results into the app. A green day means you are not fertile. A red day means that you are likely to be fertile and you should use protection.

Make sure to read the instructions of use before you get started. For the app to effectively work as a birth control, you should be comfortable with using protection such as condoms on red days.

In the beginning, the app will be getting to know your unique cycle, so you will have more red days - this is to ensure effectiveness. Once you’ve measured for a while you can get as little as 8 red days in one cycle.

Natural Cycles does not protect against sexually transmitted diseases (STDs).

Planning a pregnancy:

Natural Cycles goes beyond birth control. Our ‘Plan a pregnancy’ mode lets you know when you are most fertile and time your sex to increase your chances of conceiving.

The app will let you know when it’s best to take a pregnancy test. Once a positive test is entered into the app, it switches colours and your features change. You will now be able to track the development of your pregnancy. You can easily switch back to "Prevent".

Editors’ Notes

Understanding the complexities of ovulation cycles is hard enough. Thankfully, Natural Cycles aims to make the monitoring process a whole lot less stressful. By logging just a few vital signs, the app’s powerful algorithm can help predict crucial fertility windows, pregnancy, or even potential miscarriages. We’re also impressed by Natural Cycles’ clear, intuitive design—no cold waiting rooms to be found here.

I love this form of birth control! It’s liberating and easy and accurate!

I am 24 and have been on and off birth control since I was 18. I’ve never really liked the idea of being on long term (or short term honestly) hormonal birth controls. I tried a copper iud but my uterus rejected it 🙄 I was so close to getting an implant because I was getting pretty bad at taking my pill but then I heard about this app. I talked with my partner about how he felt about doing this and he said “if I was a girl I would use this! It sounds a lot safer than using pills or something permanent.” And that was all I needed to get off the pill. We’ve been using this app for 4 months now and I work night shift so as long as I sleep for 4 hours I can take an accurate temperature. He can also download the app so he can see my green and red days to see when we need to be more careful. I feel great using this too because when we start trying to get pregnant (3 years away but still) I won’t have to detox my body from the pill or go to the doctor to get anything removed or anything. It does take discipline to take your temp every morning but it’s worth it and easy if you have a routine. I use a sleep app called sleep cycle to make sure I’ve gotten enough hours to take a temp so that’s part of my routine ☺️

Education is power

I’m 32 and was on and off birth control for 15 years. I’ve had fibroadenomas (lumps) removed from my breasts. I suffered from sore breasts a week before my period. It took me a while to get aroused... But being OFF birth control has made all those symptoms disappear. Synthetic hormones are a huge (and dangerous) chemical disruption to your entire system.
I love Natural Cycles. I love knowing my body better. I love NOT having sore breasts before my period. I think if we could educated women about how our bodies work (with the help from Natural Cycles), then more women would ditch their birth control and actually be able to know when their ovulating.
I actually didn’t know anything about ovulation until I started using this app. I’ve also been using the PH strips and I feel extremely satisfied with this app. I’ve had sex, with protection, and knew if I was ovulating or not. That’s a strong sense of awareness.
Rather than ‘popping a pill,’ get to your know your body and let your hormones do what they were meant to do! I just love Natural Cycles and have referred it to many of my friends. The world needs more people like the ones who invented Natural Cycles!
