The goal of this observational study is to investigate the accuracy of the device in characterizing perimenopausal and menopausal symptoms including vasomotor symptoms, anxiety, sleep quality compared to self-reported symptoms via an app. The main question it aims to answer is:

What is the accuracy of the developed algorithm from the investigational device compared to daily self-report via an app in characterizing perimenopausal symptoms?

Participants will be asked to wear IndentifyHer's wearable non-invasive sensor and complete a daily electronic diary and questionnaires on stress, anxiety, and sleep.
