Natural Cycles places birth control into your own hands.
Natural Cycles is a scientifically-proven birth control option alongside the pill, IUD and the condom. 93% effective with typical use, and 98% effective with perfect use. The scientific study that determined Natural Cycles' effectiveness is one of the largest of its kind, with 15,000 women and 600,000 menstrual cycles. It was peer reviewed and published in the renowned journal Contraception.*
Natural Cycles is more than just a birth control app, the app Natural Cycles also helps users who are trying to conceive with natural family planning.. Natural Cycles can help you plan a pregnancy by tracking your basal body temperature to predict ovulation and tell you when you are most fertile. As you continue to enter your temperature, our algorithm will understand your cycle better and can predict ovulation to tell when you are most fertile.
Measure your body temperature with a basal thermometer and add your data.
Natural Cycles works by users taking their basal body temperature each morning and then adding your data into our app to help us analyze your menstrual calendar. Your temperature changes during your cycle are significant in predicting your fertile window. A basal thermometer is included with our annual subscription or can be bought as an add-on to our monthly subscription.
The app supports syncing with Apple Health.
Founded by particle physicist, Dr. Elina Berglund, with a goal to offer women an effective, hormone-free method of birth control, Natural Cycles identifies ovulation by analyzing basal body temperature, learning your unique cycle so you can get to know your body better, and know the exact days you can and can't get pregnant.

Ratings and Reviews
Understanding the complexities of ovulation cycles is hard enough. Thankfully, Natural Cycles aims to make the monitoring process a whole lot less stressful. By logging just a few vital signs, the app’s powerful algorithm can help predict crucial fertility windows, pregnancy or even potential miscarriages. We’re also impressed by Natural Cycles’ clear, intuitive design—no cold waiting rooms to be found here.
I’ve been using the app for over three and half years now once I decided to take control of my health and stop using hormones to control my erratic cycle. I don’t even remember how I found out about it, but I loved the story behind how it came about and that it was backed by science. I initially struggled with the app results because I had a highly irregular cycle (from my teen years til into my mid thirties) which generally gave me minimal green days, which was frustrating. However, I changed my lifestyle (my diet) two years ago which lead to my cycle normalising, and now I regularly see 70% green days per cycle. I’ve considered going back to other simpler apps, but there is something comforting about natural cycles, which has only improved again and again over the years with the additions to the app.
Would love to see them create a widget in future that allows us to enter the temp without opening the entire app, and the option to change the background colour on the main info page. The ‘month’ tab can also be a little daunting to absorb as its a lot of colour coding in one go, would be nice to see a more traditional style calendar layout with smaller colours used.
But I do genuinely love the messages and reminders that turn up in the app, the cycle summary I get every month and just hire simple the entire process is. I highly recommend this to anyone who is ready to start listening to their body and take control of their health.
Contraception of the future!
I have tried every contraception, all different kinds of the pill as well as implanon, mirena, nuva ring... everything but the injection. Hormonal contraception turns me into a different person, it affects my moods so badly and I feel after being on the pill for so many years and changing so often that I had just decided I was a moody person when in reality it was probably what I was putting into my body. I’m loving the natural cycles app, I think every female should have this to help learn how their own body works! I’m never going back to hormonal contraceptives. I’ve been waiting for something like this forever. This is the contraceptive of the future BUT just like everything, I think you need to read up on how it works and whether or not it works for you and your lifestyle. I do think you need to be mature enough to be prepared if it fails, in a healthy long term relationship and need to be open and discuss how it works with your partner. Works great for me and I love it!!
