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?

  • Takes the effort out

    By Mlnve
    I really enjoy using this app and have found that so far, it is really working for me. After being on hormonal birth control for 10 years, this app gave me the ability to learn to track my own cycle and become regular again without hormonal intervention. That said, it doesn’t actually do much. I have used it as a guide to learn about my cycle and will probably quit using it once my year long subscription runs out unless there becomes an ability to track/log symptoms or connect to a health tracking device that takes temperature automatically. It also boasts of 93% effectiveness, but I caution anyone who wants to use this app to learn about your cycle and how it works before blindly believing the app.
  • Amazing form of birth control!

    By sydelkins
    I started on the pill a year before I got married. The hormones completely changed who I was and made me gain weight, have mood swings, made me super anxious & depressed, & caused me to have horrible migraines. I switched between multiple different types before deciding that the pill was not best for me. I found this app and decided to give it a go in order to prevent pregnancy. Best decision I’ve made regarding my health. Love it so much! (& we’re not pregnant yet! Haha)
  • Love it (just a little feedback for improvement)

    By Ama416
    App is great. Love the graphs and explanations. But would love a better visual distinction between the color of the days and the technical terms of the cycle. For example “red day” is ovulation, “blue day” is luteal, “green day” follicular. It’s a bit hard to remember just by looking at the calendar... Also, you should backlight the thermometer screen. I wake up at 5 AM and have to either turn on a light to enter the info in the app / use my phone to see the temperature. Otherwise this is a great app. Super fun to use, etc.
  • Birth control review :)

    By lz990
    Worked so far ! This type of birth control is great for people who can remember to take their temperature everyday but if you are not one of those people it will be very difficult. I used to take the pill everyday so now I just take my temperature everyday instead. This is great for me because I already had the routine. If you are not getting Green Day’s don’t worry they will come ! It took me about 3-4 months to start getting semi regular again after taking conventional birth control. I stopped getting my period completely because of the pill for about 4-5 months so it took a little bit for my body to adjust off all the hormones. Takes some patience but my body feels SO MUCH BETTER being off hormones.
  • I love it!

    By ashdrade
    I am 26 and I am extremely sensitive to hormonal birth control pills. I’ve tried the non-hormonal IUD and I also hated it. This is such a fun way to track my cycles and allow my body to do what it is supposed to do without all of the side effects that come along with hormonal bc pills. If you follow the app exactly it is very effective! As a woman it is nice being more in tune with my body! 5 stars!
  • Great For Any Woman!!

    By Nickname1287
    I absolutely love this app! I was on birth control for about 9 years and then decided to come off 7 years ago but was never able to track my cycle. The Natural Cycles app has given me so much information about my cycle and when potential ovulation will be. What I love about it is that you can make the transition from preventing a pregnancy to planning for one and if you’ve been consistent in measuring and tracking your period you have so much information already! They also give helpful messages that educate you about your period and ovulation. I’m so happy my boyfriend and I decided to use this approach, I have not been disappointed and would recommend this to any woman whether she’s in a relationship or not!
  • Highly recommend!!!!

    By aliceamc
    Not only has this app freed me of hormonal birth control, but I have learned SO MUCH about my personal cycle and how it effects my everyday life. The data this app allows me to interact with has improved my self awareness and overall well being!! Couldn’t be happier, feel so fortunate that this is an option for women. Yes yes yes.
  • Unreliable

    By kate_ikins
    About to go through my third thermometer. After 3 months each has stopped working and I’ve had to send in for a new one. Meaning the entire cycle before was tracked wrong and half of the next cycle can’t be tracked while I wait on a new thermometer.
  • From a seasoned Natural Family Planner...

    By Edmistica
    This app is great! I have been taking my temperature for seven years. I recently started using this app to keep track of my temperatures and I LOVE it. It is well worth the full version. I’m on my eighth cycle using this app and am still going strong! My husband and I only use the green days. I have about 18 usable days per cycle, which is plenty for me! I only wish that it wasn’t so expensive to continue to use. $80 for a years subscription is pretty steep, and becoming a Star Cycler is not easy. The price may end up being the reason I have to stop using it eventually.
  • The Perfect Way yo Plan/Prevent Pregnancy Naurally!!

    By TheOriginalKB
    I love his app! I love the way they send you messages with fun quizzes, info or updates on your data. I enjoy the aesthetic and layout of the month, day and graph views. I found this app to be EXTEMELY accurate in preventing pregnancy and just as accurate in helping us plan our pregnancy! I love all of the information they provide. With other apps you take your temp and you’re on your own to interpret the data but with Natural Cycles they provide all of the information you need to know your body better than any one else!! Could not recommend this app more!
