See Why Women Love Using Natural Cycles

I finally have control over my body! It's been 6 months and it was the best decision I have made
Andrea
Not only has this app freed me of hormonal birth control, but I have learned SO MUCH about my personal cycle and how it affects my everyday life
Alice
Been using Natural Cycles for 1 full year, it's the best thing I have done after years of struggling with the pill, implant, injection...
Bethany
Natural Cycles has basically changed my life. I REALLY struggle with hormonal birth control and I've been looking for another option for a long time
Susanna
BEST. APP. EVER! I recommend it to all my friends. Who needs harmful birth control in your body when you can take control of your body in a natural way. Our fertility is not a problem that needs to be solved but a blessing that we can manage in this way. I’ve been cycling with NC for 27 cycles and have successfully prevented pregnancy this entire time. Happy cycling!
Riley
I love this app! It is so accurate! It's easy to use and it has already (after only three months) taught me so many new things about my body and female fertility. I adore the small tidbits of information that are delivered each day and I find myself reaching for my phone the moment I've taken my temperature to put it in the app, see my graph and learn something new
Hedvig
I love this app! Too tired of being on pills which cause so many troubles, but this thing is absolutely amazing! The app gives you a lot of information about your cycle and predicts safe days and periods. You can also show it to your doctor if something goes wrong.
Alexandra
I love this app. I thought at first that I wouldn’t be able to trust it but it has been so accurate and continually teaching me the correct way to measure or put in info or even about my body. I love that I get a “good job” every now and then. I also love that I am not on a hormone birth control!!
Rose
I’ve been using this app for birth control and it has not only been effective but super accurate for telling me when my period will start. I did this method before but with the fertility awareness method where you have to manually chart your temperature and cervical fluid so this is the modern version to that. I highly recommend!

Know Your Fertility in 3 Quick Steps

Step 1

Measure

When you wake up in the morning, use the Natural Cycles thermometer to take your temperature.

Step 2

Add data

Enter your temperature into the app and let Natural Cycles analyze your unique cycle and identify your fertility status.

Step 3

Check your status

Discover if today is a red day (use protection) or a green day (you’re not fertile - no need to use protection).

Your Cycle. Your Data. Your Choice.

Get to know your body with a hormone-free birth control app, so you can prevent pregnancy on your own terms.

Dr. Elina Berglund, Founder

Like many women, Dr. Elina Berglund dreamed of one day having a family.

She had been on hormonal birth control and wanted to find a natural solution that would allow her body to get back to normal before trying for a baby. Without many hormone-free options on the market, Elina decided to do something to change that. As a particle physicist that had been a member of the European Organization for Nuclear Research, she set out to develop the solution she (and so many others) needed. Working alongside her husband, Dr. Raoul Scherwitzl, Natural Cycles was born.

Elina developed a science-based algorithm based on basal body temperature changes throughout the menstrual cycle – something that is well-known and well-researched – that can predict when a woman is fertile and when she is not. Accounting for factors like sperm survival, temperature fluctuations, variations in cycle length, ovulation day, and more, the algorithm is able to show women detailed information about their unique cycles and inform them when to use protection to prevent a pregnancy (or alternatively when they are most fertile - for those looking to conceive).

We are pioneering an era in which women are more aware and in control of their bodies than ever before. We want to empower women to take control of their fertility and inform them when to use protection or abstain from sex to prevent a pregnancy.

The app is simple to use - you input your basal body temperature in the morning using the Natural Cycles thermometer and it will calculate your daily fertility status to determine whether you should or shouldn’t use protection that day. It is 93% effective with typical use, and 98% effective when you use condoms on red days. If you’re looking for a birth control method that fits into your lifestyle and is hormone-free, download the Natural Cycles app today and take control of your body, your cycle, and your method.

No method of contraception is 100% effective. Natural Cycles does not guarantee that you cannot get pregnant, it only informs you whether and when you can become pregnant based on the information that you enter into the application.
