Wristband Replaces Thermometer in Natural Cycles' Birth Control App

Natural Cycles is introducing a wristband that measures skin temperature, heart rate, and movement during sleep to replace its traditional thermometer for users of its FDA-cleared birth control app. The newly launched wristband costs $129.99 and syncs with the Natural Cycles app, which uses an algorithm to determine a person’s “daily fertility status.” Users can already track their fertility by pairing an Apple Watch or Oura Ring with Natural Cycles, but the wristband offers an alternative option for those without these devices. The wristband is expected to be compatible with newer Samsung Galaxy smartwatches and the Galaxy Ring, while also supporting older models. The addition of the wristband aims to enhance user experience and provide more convenient options for tracking fertility, making Natural Cycles a comprehensive solution for reproductive health management.
