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. You must have a subscription to be able to use the app. A free demo mode is available showing how the app works. 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. 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?

  • So thankful for Natural Cycles

    By MountainValor
    Prior to getting married I tried going on oral contraceptives which made me feel absolutely miserable! I had already felt a little hesitant with adding hormones to my body. After further research regarding oral contraceptives, I came to the conclusion it wasn’t for me. I heard from a friend about Natural Cycles & the way it transformed her natural family planning! She has had great success in it. I got married in September 18’ & have been using this app for 10 months. I LOVE it. It’s been super user friendly - the hardest adjustment initially was getting used to taking my temperature regularly. However, the notifications did help with that. It’s actually been super fun to feel more aquatinted with my body’s rhythms. My husband also feels like he can study me & know my body better as well which has been great. When I’m approaching my period, he’s prepared for my freak-out PMS. Our goal being newly weds has primarily been to prevent pregnancy. Having not used any other form of protection (except for pull-out on red days) the last 10 months, I can say confidently this APP has worked successfully for us!!!
  • The best non hormonal option by far!

    By Adriannamaria
    I choose to stop taking “the pill” because I had so many negative side effects, it was crippling my daily life with constant nausea, horrible moods swings, I was so desperate to find something that works, this app has completely changed my life and my families life...
  • Never Going Back!

    By 🐷💗
    I’ve been using Natural Cycles for 2 years. I started up when I got off the pill after 10 years and was looking for an effective form of birth control that didn’t require medication. I’m never going back! I can trust the recommendations they give and feel more in touch with my body and it’s cycles. The app teaches you along the way if you are new to this, as I was, and grows more precise the longer you use it.
  • Easy, interesting, accurate

    By mauigirlfriend
    Easy to use. Fascinating to track. I feel more in touch with my cycle than I thought possible.
  • Getting there

    By Sconstantin
    I’ve been using NC for a year now and I’m pretty happy so far. My body is still adjusting to itself after removing my Mirena, there’s a learning curve but everything is making more sense. Very happy.
  • I am a fan

    By abby_purposed
    I like this form of birth control. My only complaint is that sometimes it switches the ovulation day - but that is probably because I didn’t measure temp consistently enough...
  • Pregnant in 2 months

    By allllreadydone
    I used this app for less than three months and I’m already pregnant. I never even had sex during the green days because I was waiting for the app to really learn my cycle, only had unprotected sex on the days I had my period. The app sounds too good to be true. I wouldn’t trust it.
  • $$$ ridiculous $$$

    By geralddeen
    I started seeing adds for this and thought I wanted to try it but no where did it ever say that it’s $99 a year or $30 a month. no free trial or anything. I used a period diary app 3yrs ago and got pregnant with my daughter IT WAS FREE.
  • I LOVE this app

    By dahliamama
    This app is everything! So convenient Easy to understand FORCES the user to get to know their body FORCES clear, open, honest, communication with the partner Easy to travel with No more acne No more foggy head No more chronic UTIs (Also I pull it out when the dr asks when the first day of my last period was because I never remember)
  • Absolute best natural BC!

    By paigebondley
