Introducing digital birth control. A natural method of birth control that uses a smart algorithm to learn your cycle and identify your ovulation by analyzing your basal body temperature. Natural Cycles is for women over the age of 18. Natural Cycles does not protect against sexually transmitted infections (STIs). Natural Cycles is only available as a method of birth control in the USA and Europe. In countries outside the USA and Europe, Natural Cycles is intended to be used as a fertility tracker. Natural Cycles is 93% effective under typical use, which means that 7 women out of 100 get pregnant during 1 year of use.* No method of contraception is 100% effective, even when using the app perfectly you can still have an unintended pregnancy. Natural Cycles shows you: ○ How your unique cycle works ○ Daily updates on where you are in your cycle ○ When you are in the fertile phase of your cycle and need to use protection (e.g. condoms) ○ When your ovulation is detected and predicted ○ When your period is coming up and when you can expect PMS ○ The science behind your menstrual cycle Natural Cycles is: ○ The first digital method of birth control available in both the USA and Europe ○ Backed by scientific research ○ CE marked & FDA cleared Pricing Plans: Yearly plan: 79.99 USD/year. Free thermometer included. Monthly plan: 9.99 USD/ month. Thermometer not included. Free trial: 30 day free trial. Thermometer not included. To use the app you need a two-decimal basal thermometer. Precautions: ○ As a contraceptive, Natural Cycles may be less suitable for you if you have irregular menstrual cycles (i.e. cycles shorter than 21 days or longer than 35 days) and/or fluctuating temperatures as predicting fertility is more difficult in these circumstances. Natural Cycles’ effectiveness as a contraceptive is not affected by irregular cycles, but you will experience an increased number of red days, which can reduce your satisfaction with Natural Cycles. ○ Natural Cycles does not protect against sexually transmitted infections (STIs). Use a condom to protect against STIs. Want to learn more about Natural Cycles?

  • One Year In

    By Rendies
    I have been using NC for over a year. I have really gotten in the habit of tracking and learning about my cycle. I love the education part the most and it would have been great to have been this informed at a much younger age. My biggest regret in life is subjecting my body to hormonal birth control for almost 2 decades and not realizing how unnatural it was and the harm it was doing to my fertility. I am hopeful this app helps me conceive but so far the ovulation day has been hard to pinpoint. I’m impressed with the ease of use, the interface, and the updates. This app has come a long way over a year and continues to improve. Hopefully I’ll be able to provide a 5 star update down the road.

  • One year on NC

    By Catwoman <3
    Loved it so much so far. There’s not better feeling than being in contact with your own body and learning about my cycle. It’s empowering what NC is doing with this app. Thank you so much for helping me gain self confidence in this beautiful and natural way !
  • More Than Just A Period Tracker

    By kmilita
    How do women in this day and age do not know about this app? This app gives you vital information about your health and can help you plan for pregnancy when you are ready for that. Body temperature is actually a indication of health (are you normal, lower than other cyclers, etc). Also, understanding how long your periods are, WHEN you ovulate, IF you are ovulating. All such important factors. Highly recommend.
  • Loving it!

    By CaitLeow
    I’ve been using Natural Cycles for over a year now and I’m loving it. It feels like magic to have an app that prevents me from getting pregnant and that when I do want to conceive all I have to do is switch a setting. I feel more in tune with my body and I don’t have as many mood swings like I did on the pill. Thank you Natural Cycles for literally changing my life!
  • Love!

    By Braker21022
    I love this app! I have been on hormonal birth control on and off for years, I tried the copper IUD, and everything made me feel “off”. After our second son was born, we decided to hold off on having another baby and we used the app to track everything. It worked wonderfully for us! Now we are ready to have a baby and we are using the app that way, so far so good!
  • Doesn’t Work

    By YakobTheYak
    In short, my wife and I did everything right according to the Natural Cycles algorithm. We recorded her temperature every day at the same time (6am), we abstained on days when the app said we were fertile, and only had sex on the days when we were not fertile. We are now pregnant with our first child. $80 down the drain, for an app, and an algorithm that does not work.
  • The natural choice

    By ChiaraSan89
    Among all the fertility apps, Natural Cycles is the only one that can be trusted for contraception - it has a real algorithm, an easy-to-use,uncluttered app, clinical trials, FDA clearance. Like with any other contraceptive, it’s not 100%, but it’s non-hormonal, more effective than other non-hormonal alternatives & you get to know your body.
  • Worth it

    By GabriellaBella77
    This app is a great way to learn more about your body and your cycle. The app is very user-friendly. Plus, it’s an all natural and non-invasive contraception. No chemicals! No problems!
