Introducing the intelligent birth control app. Natural Cycles is a hormone-free method of birth control that learns your unique cycle. The app identifies ovulation by analyzing your basal body temperature which you should measure when you wake up. 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. The app also integrates with the Apple Health App. Natural Cycles is 93% effective under typical use, which means that 7 women out of 100 get pregnant during 1 year of use.* Natural Cycles is 98% effective with perfect 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 and only birth control app available in both the USA and Europe ○ Backed by scientific research ○ CE marked & FDA cleared Pricing Plans: Yearly plan: 99.99 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 intelligent app you need a two-decimal basal thermometer. Precautions: ○ Natural Cycles’ effectiveness as a contraceptive is not affected by fluctuating temperatures and/or irregular cycles (i.e. cycles shorter than 21 days or longer than 35 days). However, you will experience an increased number of red days as predicting fertility is more difficult in these circumstances. ○ Natural Cycles does not protect against sexually transmitted infections (STIs). Use a condom to protect against STIs. Want to learn more about Natural Cycles?

  • Family Planning

    By Queen Ty
    We used this app to help us conceive. It has been great! I’m almost 6 weeks pregnant. I really enjoy the “Preggo Cycler” mode. It helps me stay informed about my cycle and where I am in pregnancy.
  • Not pregnant!

    By mommie rosie posie
    I have been using natural cycles for over a year now in my long term monogamous relationship. It has worked perfectly for us! It is so nice having a better understanding of how my body functions. After the first 3 months of having unprotected sex on my safe days, I was no longer ever worried about not getting my period each month. The fertility awareness method really does work!
  • Responsible way to plan your family naturally

    By CatholicAnswers
    I wish I would have found this app sooner! Natural cycles takes the headache out of trying to understand your fertility. The algorithms work! Thank you for creating a reliable, accurate, trustworthy, simple and efficaciously method for NFP. This isn’t just a solution, but the solution for natural family planning. They’ve taken all the guesswork out of the equation. Worth every penny!
  • Life changing

    By J ramarama
    I’ve been using this app for over a year now. I picked up a book on learning about my fertility in conjunction with using this. It’s sad that people aren’t taught more about their bodies! We are told that mediations and devices will do what our body is plenty capable of doing. Anyhow - I love it. It’s easy and has become second nature. I still freak out every couple of days thinking I forgot to take the pill and sigh relief when I am reminded of my new reality. I’ve told everyone about this app!
  • Seems Useful

    By im_stewie_griffin
    $10mo or $100yr. I wish it were cheaper so I could buy it.
  • Excellent natural birth control option

    By KSong18
    My husband and I have been using Natural Cycles for the 6 months we’ve been married, and it’s been a really positive experience! I have never used hormonal birth control, as the idea of overriding my body’s natural rhythms with synthetic hormones has always bothered me. I’ve loved building an understanding of my own fertility - it’s really empowering! When we do decide to have a baby, I think the knowledge we’ve gained of my cycle will aid us in planning conception :) As others have mentioned, it would be great if the app included cervical mucus tracking, the ability to track symptoms/miss at various times of the month, and Bluetooth capabilities in the thermometer.
  • Love the app

    By alanah st
    I love everything that natural cycles has in the app! The only thing I would like to see would be a tracker for cervical mucus!
  • So much more than an app

    By ChiaraSan89
    I always wanted to go hormone-free, but the available options out there didn’t suit me. Copper in my body was not option, just using condom or withdrawal felt like giving up and i never trusted the accuracy of period/fertility apps. When i read that the FDA approved Natural Cycles for birth control and the effectiveness rates were higher than other non-hormonal options, I decided to go for it. More than 6 months into it, i must say that this app is so much more than just birth control. You get to know yourself to a whole new level - so powerful. I love how energetic i feel around ovulation. Note that you need to be ok with using condoms in the beginning until the app gets you, but after that i get a decent amount of green days. You also need to measure your temp every morning, i can see how this is not for everyone, but it’s a game changer for me!
  • Review of Demo

    By I have teeth
    (I have not purchased this subscription yet) First impression of the app. Very clean, neat, simple and packed with information to answer all questions I have. The demo version of the app is a great way to see if this app makes sense to you and is worth purchasing. I can say that after looking at reviews online and experiencing the demo app, I will be purchasing the 1 year subscription. (Keep in mind there is also a monthly option of $9.99) The app is beautiful and you can clearly see the hard work that was put into this to make it a great experience for women who do not prefer our modern medicinal methods of birth control.
  • Get back to your natural period and understand it for the first time

    By e.e.atkins
    As an athlete, I love that Natural Cycles tells me so much more about each stage of my cycle - what to expect and when to expect it! Also, my cycle has always been closer to 30-35 days long, and I had a hard time keeping track of it due to the fact that it wasn’t a perfect 28. I also falsely considered myself irregular - but really only because, even as an adult, I didn’t understand enough about what normal is! There is a huge issue in my sport with the prevalence of amenorrhea and the underlying health issues can be masked by hormonal contraceptives for years. So if you would like to get back your natural period - and the valuable health feedback that it provides - I highly recommend Natural Cycles!
