Natural Cycles, Birth Control & Ovulation Calc App Description & Overview

Natural Cycles helps you keep track of your ovulation, period and fertility. The app will show you when to use protection to effectively prevent a pregnancy. It is clinically tested to be 99.5% effective*. *Natural Cycles has a method failure Pearl Index of 0.5, which means that 5 women out of 1000 get pregnant during one year due to a falsely attributed green day. Natural Cycles has a typical-use Pearl Index of 7.0, which means that in total 7 women out of 100 get pregnant during one year due to all possible reasons (e.g. having unprotected sex on red days, failure of the contraceptive method used on red days). Natural Cycles analyses your temperature, period and ovulation to calculate when you are fertile and should use birth control (e.g. condoms). Our algorithm is the brains behind the app. It takes care of all the complex calculations and tells you everything you need to know about your cycle. How it works: Measure your temperature first thing in the morning before you get out of bed. You will need a two decimal basal thermometer to do so. Enter your measurement and other data such as period, sex and LH test results into the app. A green day means you are not fertile. A red day means that you are likely to be fertile and you should use protection. Make sure to read the instructions of use before you get started. For the app to effectively work as a birth control, you should be comfortable with using protection such as condoms on red days. In the beginning, the app will be getting to know your unique cycle, so you will have more red days - this is to ensure effectiveness. Once you’ve measured for a while you can get as little as 8 red days in one cycle. Natural Cycles does not protect against sexually transmitted diseases (STDs). Planning a pregnancy: Natural Cycles goes beyond birth control. Our ‘Plan a pregnancy’ mode lets you know when you are most fertile and time your sex to increase your chances of conceiving. The app will let you know when it’s best to take a pregnancy test. Once a positive test is entered into the app, it switches colours and your features change. You will now be able to track the development of your pregnancy. You can easily switch back to "Prevent". KEY FEATURES - Red and green days to tell you exactly when you should use protection. - Ovulation calculator and detector - Intuitive data entry – temperature, ovulation test results, period - Interactive calendar showing your current and upcoming fertility status - Personalised fertility predictions up to 5 cycles in advance - Informative graph view - Statistics from your cycles and fertility - Integration with Apple Health app ‘Plan a pregnancy’ mode: - Personal fertility scale to pinpoint the optimal days to conceive - Pregnancy detector - Information about your baby’s development SUBSCRIPTION Natural Cycles includes In App purchases for the auto-renewable subscription to the application.

Natural Cycles, Birth Control & Ovulation Calc Reviews

  • Get to really understand your cycle with this fantastic app.

    This app is fantastic. It does it all from tracking your cycle to warning you "you should start your period next week you may experience some PMS now" to helping you keep track of sexual activity and really become more aware of your body through keeping track of the cycle of change we women go through so frequently! My nutritionist recommended this app to me and I recommend this to everyone who is a candidate for it. It is very easy to use and you can at anytime switch the option on your profile from trying not to get pregnant to trying to conceive so this app can follow you down the different paths you choose to take with your body. So so happy I found this app and am now more in charge and aware of my own body!
  • Loving this app!

    I've been on and off of BC pills for about 14 years. Always was worried about the hormones I was receiving due to my high risk to certain cancers that run in my family. Now I don't have to worry about that! I was dreading having to try out the copper iud after hearing so many horror stories. Then this app came along and it is a game changer for me for sure!
  • The app is only as good as the thermometer...

    I'm sure that the algorithms and the science behind the app are solid and well researched..but the app is only as good as the thermometer you use. I paid the yearly price of $64.99 (which seemed like a ridiculously exorbitant price, but when you want a baby you get kinda crazy) and got the "included" thermometer with it. I was super excited to start tracking my temps and really take control of my fertility, as my husband and I have been trying to get pregnant. I started temping and tracking immediately. After about four months I was convinced that I had hypothyroidism (temps below 95 on waking), that I had a luteal phase defect, and I still wasn't sure when I ovulated, if I even was! My graph looked like a mountain range with little discernible thermal shift. I started to doubt my thermometer's accuracy, so I hopped on Amazon to look at others. Lo and behold, I found the EXACT same thermometer I owned and it was literally the cheapest one you could buy. Many of these reviews confirmed my doubts. I bought a new thermometer (babico, if you're wondering), and when it came I took my temp with BOTH thermometers at the same time. Wouldn't you know, my temp was a whole degree LOWER with the thermometer I'd been using for months. If that doesn't frustrate a person thinking you wasted four months of trying to get pregnant I don't know what would. I absolutely would not have trusted it to keep me from getting pregnant if I were trying to prevent! Since using my new thermometer, my temps have been rock solid and I have clear thermal shifts on my chart, and what do you know? Everything is completely normal. *** Bottom line: Use the app, although plenty of other apps out there do the same thing with options to add more info (if you're trying to conceive, I can't speak to preventing), but DON'T USE THEIR THERMOMETER!! I doubt I'll re-subscribe 🙄

    Great app and excellent technique. Would highly recommend
  • Wish it was prediction, more solid.

    I paid the $64 and love that I can keep track of my cycle, it makes me feel more knowledgeable into my body's cycle. However, I do with the algorithm was more solid and less predictive. Every day is red, and says "use as a prediction" and not "this is right". I love the app for keeping track, but definitely hope there's more ground to stand on the longer I use it. (Have been using for 3 months)

    I can't describe how much this app has improved my quality of life! Since 16 yo I'm using pills and after ten years the first side effects started to hit me very hard. After gaining more than 20kg, one emergency visit to hospital due trombose and intense variation of my humor, I decided to quit. Natural Cycles replaced the pills wonderfully! Even with a irregular cycle like mine, it is pretty accurate. I wish I could have known it earlier! I highly recommend this app!
  • Amazing App has changed my life!

    I have always been a person who had to take several meds for this or for that. When I decided to start cutting back on the amount of meds I take and ridding my body of chemicals, I discovered Natural Cycles as a form of BC that didn't require an implant or a pill. I feel more in touch with my body and it's rhythms, I can keep ACTUAL track of ovulation and my periods. Now if I do decide to get pregnant, I don't have to worry about three months of flushing BC out of my system, I can just flip the switch in the app to "trying to get pregnant" and away me and my husband go!!
  • Great app!

    Very useful and accurate!
  • Great app because SCIENCE!

    By Michbuggie

    One of the best apps on my phone. If you measure your temp every day (or almost) the data it gives you is very accurate and the more "green" days you get. My husband & I have used this for a year with no problems. It isn't as bulletproof as hormonal BC, but if you can handle the slightly increased risk, it's worth it (you can decrease risk by combining this with withdrawal). The design of the app is great--it's easy to use and they provide a lot of useful info from your data. Also, I like that I'm participating in research that will make this app and our understanding of fertility better in the future. (And they're good about asking for permission before viewing any of your data). Brilliant app for people sick of hormonal BC.

    I love that this app is available. I am so grateful that I have an alternative to birth control pills. I have never felt so good! I was on some form of hormonal birth control from age 18-35. Now that I've been cycling for a year and a half, my life is drastically different. I have lost weight effortlessly and have a better relationship with my husband. In my opinion, this is all due to the fact that I'm not on hormones. I love that I am in charge of my fertility and not reliant on a pill. Someday we may want to plan a pregnancy as well and I am so grateful that this app can help us with that too.
  • Natural birth control!

    I've been using Natural Cycles for nearly 2 1/2 years. After 2 pregnancy scares with LadyComp, I was excited to find this app. This is not Lady comp or Daysy, it is different. I used Ladycomp for 7 1/2 years and sold it. I would recommend this app for birth control. It is proven similar effectiveness to the pill. A perfect use Pearl Index of .5 99.5% 2 clinical studies done. NaturalCycles has around 150,000 users in 161 countries across the world! We are seriously avoiding pregnancy.It has gradually given me more and more green days as it learned my cycle. I have only 11-12 + red days per month. It is the only birth control in the world that uses this unique algorithim. The founder was a physicist in the team that discovered the Higgs Boson and recieved a Nobel Prize. Another great plus is that you can work your way up to become a Star Cycler. A Star Cycler receives NaturalCycles free for Life. NaturalCycles app provides you with Cycle Statistics. It tells you your average ovulation day, follicular phase, Luteal Phase, temperature variation and cover-line. It also provides you with the average Cycler's statistics compared to yours! I run a group on Facebook called Natural Cycles users. Come join us!!!
