Introducing digital birth control. A natural and effective method 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 for fertility monitoring. 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 only digital method of birth control available in both the USA and Europe ○ Backed by clinical research ○ CE marked & FDA cleared Pricing Plans: To use the app you need a two-decimal basal thermometer. 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. 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?

  • The greatest app I’ve found

    By Ajschwichow
    Well, like many ladies out there I’m sure, I went through a bunch of different cycle tracking apps before I found this one. I have not looked back since. It’s great to know what my body is doing, and when it’s doing it. I don’t like the idea of putting hormonal birth control in my body, and with this app I’ll never have to. Thank you natural cycles.
  • Great foundation but app is just okay

    By Pumpkywumpky638938383
    I like that this app is highly accurate and FDA approved but as someone who is trying to conceive I think there are equally helpful, free apps out there that are faster, more intuitive and informative. For someone who is using it as birth control maybe it’s worth the money, but I haven’t gotten any information from NC that I hadn’t already from Glow, which I’ve been using for the past eight months just tracking my periods and taking ovulation tests. Glow’s predicted fertile dates have been the same as NC now that I’ve been using them both (I continue to toggle between them to compare and because I find Glow to be faster and more informative) so I don’t know what benefit I’m getting out of using NC. One example of how NC is not ideal, the temperature graph and the monthly calendar don’t have dates AND cycle days - the monthly calendar has dates but no cycle days, and the temperature graph has cycle days but no calendar dates. So I end up going back and forth between those two screens a lot. In Glow, when you look at the monthly calendar and your cycle chart you can see both the calendar date and your cycle day on the same screen. I also find that the symbols used in the NC calendar are cryptic and not immediately intuitive or clear.
  • Still getting used to it!

    By campbellhl1
    So far the app has been helpful! I’m excited about having a birth control option that’s an alternative to altering my hormones. I’m in the routine of taking my temp every morning but have only been a consistent user for about 2 months. Will come back with another review in he future!
  • Education and BC

    By thatsWendy
    I started Natural Cycles after my first postpartum menstrual cycle. I’m learning about my cycle and it’s learning about me as we go. With my cycle being so irregular I’m getting a chance to see where I’m at and will eventually have a clear understanding of my personal pattern. No other form of BC gives you a better look into yourself AND grants you power in your pattern. Knowledge is powerful.
  • So far

    By Suzanna Lester
    I’ve only been through two cycles, but this makes me so happy! It’s fun to learn more, and see where my body is today, and it’s DEFINITELY exciting to having a few days without condoms! (Although, if I wasn’t in a very committed relationship, I wouldn’t have any problem with our rubbery friend, ladies, stay safe! I’m just glad to have this alternative for me – anything’s better than the other crap we do/put into our bodies.)
  • Worth committing!

    By OpalP12
    Don’t be fooled! It will take a bit of time (4 months for me) before you will have consistent Green Day’s and if you are preventing pregnancy as I am, you should always have a back-up plan at the ready. I cannot stress the benefits of my personal experience with this app. Knowing my body, keeping track of what is going on and general health awareness is so powerful.
  • Great idea, but a bit tricky for parents of young kids

    By chloe and the gang
    I’ve been on natural cycles for about 4 months now and I really like it! I will say one that is tricky as a parent of 2 young kids, is that I have to get up during the night. And often get woken our early in the morning- making it hard to get accurate readings of my basal temperature. This app is not really for parents of young kids, I feel. “Take your temp right before getting out of bed in the morning”- well, I’ve been up 3 times during the night, and am getting up at 5.30am to attend to a toddler- hard to know when to read your temperature......Another thing i miss with this system is a thermometer that has a light-up screen for reading your temp! Since your supposed to take your temp first thing before you get out of bed, it would be nice if I could read the temp without turning on the light and wake up my husband at 5.30 am....! Despite this I do love the idea of this app! I can’t do the pill anymore as the Hormones give me really bad mood swings. Condoms are no fun as a long term solution for a married couple....As my kids are sleeping through the night more, I’m getting better at taking my temp, I feel it’s working really well!
  • So thankful I found this app!

    By A.F-Ellen
    My husband and I have been talking about different birth control methods for a while now and this was like an answer to our prayers! Hormonal birth control really messed with my body, horrible mood swings, high blood pressure plus several other symptoms, and after 10 years I wanted off, but still didn’t want to get pregnant. Then I find this! It’s a little frustrating in the beginning with so many red days, but better to be safe. Can’t wait until I’ve been logging for a few months and it really gets to know my cycles.
  • Never going back

    By sexmeg
    I will never alter my body by taking synthetic hormones ever again. Natural Cycles makes me feel empowered and in control. I’m amazed by my body the more I learn.
  • Saving Grace

    By kbugRN
    This app has been a breath of fresh air! Birth control took away my libido, increased my migraines and made me feel like I didn’t have any other choice. Then I found natural cycles! I’ve been using it for 3 months now and I feel like a new person! My relationship is thriving and I feel like myself again!
