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.
My husband and I use this app to aide us in NFP. It has been amazingly accurate and so great! I think what this app does to empower women to learn about their bodies and take charge of their fertility in a healthy and natural way cannot be understated. Thank you so much for this wonderful tool! If I could make a suggestion though, it would be maybe to tweak the wording of a particular message. I had my profile set to prevent pregnancy mode as my husband and I have not been actively trying for a baby. However, we are a couple who is open to life, so there are times (through no fault in the app) that we are knowingly intimate on a red day. I just found out that I am expecting and hit the follow pregnancy function. I was disheartened to get the message that said you were sorry I got pregnant while in prevent pregnancy mode. Now, granted I am someone who looks at all new life as a joy and a blessing, regardless of it being planned or unplanned, but for someone who may be more surprised and scared about an unplanned pregnancy may take that message to heart and it can be really discouraging. May I suggest that regardless of the mode a cycler is in, that you greet them with a message of joy and encouragement? Instead of “we’re sorry”, just say “congratulations” and then go ahead and have them take the survey you put in the message. This app is so amazing at spreading positivity and empowering women and I just think that should consistently be represented throughout.
Easy to use, reliable
I have been using Natural Cycles for a little over 6 months now and I love it! I have never been on any birth control and didn’t want to start any when I got married, but my husband I were getting tired of having to use condoms every time so when I saw this app I figured it couldn’t hurt to try it out. I keep the thermometer on top of my phone at night so when my alarm goes off I take my temperature right away and log it. Some cycles I do get a lot of red (use protection) days if the app has trouble detecting ovulation, but it’s still way better than having to take birth control or use condoms every time. I also like that I am aware of my body and cycle more now. I would highly recommend this app to anyone that is married or in a committed relationship where if you would get pregnant it wouldn’t ruin your life plans. I feel that it is very reliable if you use it properly, but there is room for error so if getting pregnant would devastate you, this probably isn’t for you. But for us, we aren’t currently trying to have a baby but probably will in the next year or two so I feel comfortable using this and realizing that there is a chance i could still get pregnant. Plus when we do decide to have a baby, knowing my cycle will hopefully make it easier.
