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.

○ Yearly Plan (Recommended): $89.99/year.
○ Monthly Plan: $9.99/month.
○ A subscription is needed to use the app, and while a free demo is available, we recommend a minimum of 2-3 cycles for Natural Cycles to be most effective.

○ No method of birth control is 100% effective, even when using the birth control app perfectly you can still have an unintended pregnancy.

Very happy

This app does all you need to get more in touch with your cycles. Never thought that at the age of 34 I would finally really get what is happening and also grow a bigger understanding of how it affects me on my daily life state if being. I will offer this app to all my friends and most of all to my dear daughters, as I think it's a very valuable asset to help understand ones own body and energy. So happy this is here.
