Natural Cycles - Birth Control App Details

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?

App Reviews

  • So helpful and so easy to use!

    By Bre Eggers
    I have been wanting to use this method as my form of birth control ever since I heard about it and this app makes it SO easy. I have been using Natural Cycles to prevent pregnancy for about 6 months now and though it took me and my partner a little over a month to fully trust it, we are now fully dependent on this app as our form of birth control! No hormones, no side affects, just science(+ no babies yet)! LOVE IT.
  • Will never go back

    By jennifer11791
    I’ve been using Natural Cycles a little over a year and I absolutely love it. I hated taking the pill because it changed so much about me. I went off and just wasn’t comfortable not having any protection besides condoms. This gave me back the control and really helps you get to know your body in a non harmful way. I did a lot of research before starting to make sure it was effective, and that is what convinced me. Now after using it for a year, I can’t imagine doing anything else.
  • So thankful for Natural Cycles

    By ErinKaileigh
    I am so thankful for Natural Cycles! After a horrible year and a half of debilitating migraines almost daily due to birth control pills and inserts ( I tried so many of them to attempt to cure the migraine problem) I just had to a top birth control altogether. When I came across Natural Cycles I was skeptical but I thought it was certainly with a try. Best decision I have every made! Within a week my migraines were gone and here we are 6 months later still no migraines!! I highly recommend Natural Cycles as your birth control method. It will forever be mine!
  • Love this app! BUT...

    By brighton159
    I’ve been using Natural Cycles for over a year and I highly recommend it! The predictions were always highly accurate for me and I really enjoy the friendly in-app messages they send. Overall, I will say Natural Cycles has helped me understand my cycle and I feel more in touch with my womanhood. With that being said, I did get pregnant while using the app (on my own accord, not due to any miscalculated green days) and the Track Your Pregnancy function is inaccurate, not useful, and overall lackluster. But I’ve already paid for the year.
  • Best app

    By ResaRezay
    Best app to track period and use as a birth control.. VERY reliable!!
  • Not free

    By gemmorala
    It is really annoying, when they recommend these apps, and downloading the app is free, but once you downloaded, it pops out an screen saying that you have to pay a crazy subscription for 10.00 dollars monthly or 80.00 yearly.
  • Must Have!

    By artarter
    This is essential. Best period tracker I’ve ever used.
  • Great

    By aeb09f
    I love this app, makes it easy for natural cycle tracking. Was on birth control and an IUD and got so tired of all the various side effects. This way is far more information as well. I would only recommend this for those with a regular routine though-consistency is key.
  • I know my body

    By Simranrealness
    I love this app and it’s simplicity. It is the first app that is able to pinpoint the start of my period and even my ovulation when I commit to measuring daily so I know the days that are “safe” to be a big lax on protection. This is a great method as me and my partner are monogamous and he really dosen’t like using condoms all that much. But I know when I have red days those are the most important to use. Definitely use the LH test strips as they make a world of a difference in determining your ovulation dates. Love this app and look forward to continuing to use it!
  • Easier than I expected!

    By jenbunnyyy
    I’m 27 and in a relationship with a cis man. I’ve tried the pill, which made me feel crazy (and the idea of taking synthetic hormones long-term yucked me out). Several years ago I got the copper IUD - I liked that it was hormone free and that I didn’t need to remember anything daily. But my period pain has gotten worse & worse, and I’m wanting to take it out. I decided to try this method because it’s one of my only hormone-free options besides barriers. I was worried about remembering to enter my temp at the right time every day, but the algorithm has impressed me. I’ve gotten better at remembering to measure, but I’m still not perfect. And yet the algorithm has narrowed it down to one week of potentially-fertile days. I haven’t verified with LH tests, but I plan to soon. So far, I’m very happy with Natural Cycles and, of my ovulation tests match the results in the app, I’m going to take out my IUD and be allllll natural :)
