The goal of this observational study is to build knowledge about the path to menopause using subjective, self-reported and objectively measured information from multiple wearable study devices and a smartphone app. This study is being done in female individuals who are 35-55 years of age. The eventual aim of this work is two-fold; 1) to increase knowledge, awareness and education for individuals and clinicians about the lived experience of perimenopause and menopause through objectively measured data from digital study devices, and 2) to develop approaches to empower female individuals to manage this transition by learning what improves or worsens their symptoms.
