Natural Cycles birth control app is the first and only FDA-cleared & CE-marked hormone-free contraceptive. Unlike your daily radio stream, you only check it once per morning. Plus, more than 6M women trust science—not hormones—to prevent or plan pregnancy.
Why this Natural Cycles birth control app works
This system was created by a Nobel Prize-winning physicist. Each morning, you take your temperature manually or sync with a wearable like Oura Ring or Apple Watch. Then, the algorithm tells you if it is a "Green Day" (safe for unprotected sex) or a "Red Day" (use protection or abstain).
There are no hormones, daily pills, monthly injections, or clinic visits for refills.
How effective is this method
With typical use, it prevents pregnancy 93% of the time. However, with perfect use, that rate reaches 98%. In addition, more than 25 peer-reviewed studies confirm these numbers. Today, over 6 million women worldwide currently use this approach.
Meanwhile, the App Store rating sits at 4.8 stars from more than 58,000 reviews.
What other features exist beyond pregnancy prevention
You can switch to "Plan Pregnancy" mode when you want to conceive. Additionally, there are specialized modes for postpartum recovery (released 2024) and perimenopause support (released 2025). Their new NC° Band wearable also allows overnight temperature tracking without morning effort.
Who should use Natural Cycles birth control
This option works well for women who want hormone-free contraception, whether they have regular or irregular cycles. It is also helpful for women planning pregnancy in the future or navigating perimenopause. Furthermore, it supports those recovering from childbirth or miscarriage.
How to get started
