Clarity through every phase. Your WHOOP now integrates with @NaturalCycles, the only FDA-cleared hormone-free birth control app. Using the overnight temperature data WHOOP already collects, the Natural Cycles app provides a daily fertility status and personalized fertility insights — helping you better understand your cycle and make more informed decisions about family planning and pregnancy prevention. We're also proud to be the first wearable to include one free year of Natural Cycles app access for eligible WHOOP members. So you can spend less time wondering what’s happening in your body and more time understanding it.
