Natural Cycles Launches NC° Band, a Wearable Designed for Natural Cycles That Offers a Seamless Measuring Experience
Worn overnight on the wrist, NC° Band is a new wearable that replaces the Natural Cycles thermometer, making science-backed fertility tracking easier and more accessible.
Natural Cycles, the company behind NC° Birth Control – the first and only FDA-cleared birth control app on the market – today announced the launch of its new multi-purpose wearable, the NC° Band. Designed specifically to be worn on the wrist overnight, the NC° Band will replace the Natural Cycles thermometer in select markets.
Powered by the NC° Fertility algorithm, the Natural Cycles app analyzes hormone-driven temperature changes to confirm a user’s daily fertility status and deliver personalized cycle insights. With the launch of NC° Band, Natural Cycles offers a more effortless and cost-effective way for users to collect the biomarker data required by its algorithm.
Worn only while sleeping on a user’s inner wrist, the NC° Band automatically detects when a user falls asleep and records continuous overnight temperature, heart rate, and movement — no manual measuring or all-day wear required. With up to 14 nights of battery life, NC° Band integrates seamlessly into users’ routines while keeping all measurement data securely stored within the Natural Cycles app.
“Natural Cycles was built on the belief that understanding your body should be both empowering and accessible. Because temperature is central to our science, we’ve always envisioned creating a wearable designed for our users,” said Dr. Elina Berglund Scherwitzl, co-founder and CEO of Natural Cycles. “The NC° Band brings that vision to life. We’re excited to offer a new option with features our users have asked for while continuing to support our integrated wearable partners and giving Cyclers the flexibility to choose what works best for them.”
The new device joins existing wearable options compatible with Natural Cycles, including Oura Ring and Apple Watch, and provides a more cost-friendly alternative for users seeking a simple way to measure.
