Natural Cycles Powered by Apple Watch

Track your fertility overnight with Natural Cycles, the #1 birth control & fertility app, powered by Apple Watch. Simply wear put on your Apple Watch before you go to bed, wear overnight, and sync with the NC° app in the morning to find out your fertility status.

Let’s clear this up. #AD Not all cycle-tracking apps are created equal. They’re built for awareness, not pregnancy prevention. And that distinction matters. Here’s why: Ovulation isn’t perfectly predictable. Stress, travel, and even perimenopause can shift your cycle, meaning “safe days” may not always be safe. In fact, a recent study shows calendar-based tracking methods can carry up to 44x higher pregnancy risk per cycle compared to regulated digital birth control. That’s where a clinically validated app like @naturalcycles comes in. It uses real biomarkers (like basal body temperature and your cycle data) to evaluate fertility daily with built-in safety margins that adjust when your body changes. This isn’t about fear. It’s about being informed and empowered to make the best decision for your body. Because knowledge isn’t just power…it’s protection.

#AD There is not one birth control method that is right for everyone, and one of the most important parts of contraceptive counseling is helping patients find something that aligns with their medical history, preferences, and lifestyle. For patients who prefer to avoid hormones, or who cannot safely use hormonal birth control because of other medical conditions, having reliable non-hormonal options matters. The @naturalcycles app is an FDA-cleared, non-hormonal birth control app that uses biomarkers like basal body temperature and cycle data to estimate your daily fertility status, assigning either a “Green Day” (not fertile) or a “Red Day” (use protection or avoid intercourse). With typical use, it is 93% effective, and with perfect use, it’s 98% effective, which is similar to the birth control pill. As with any birth control method , effectiveness depends on correct use. Choosing a birth control method is about balancing effectiveness, safety, and what realistically works for you. Having more options allows for more personalized, patient-centered care.
