# Natural Cycles°

> Natural Cycles is a Stockholm-founded women’s health company whose regulated app converts temperature and cycle data into a daily fertility status. Its subscription spans birth control, pregnancy planning, pregnancy, postpartum and perimenopause, pairing a proprietary algorithm with thermometers and wearables. The company’s real moat is not the red-and-green interface; it is the expensive, slow stack of clinical evidence, medical-device compliance, accumulated cycle data and sensor partnerships behind it.
