I did not expect the best women's health tracker at CES to be this one (but it is)

ZDNET profiles Peri, a $449 perimenopause-focused wearable showcased at CES 2026 that uses PPG, accelerometer, EDA, and temperature sensors plus AI analytics to detect and contextualize symptoms like hot flashes, sleep disruptions, and anxiety; it is worn under the breast, runs 7–10 days per charge, logs sleep/anxiety/activity/cycle data, and supports tracking hormone therapy impacts. Available for preorder and slated for a December launch, Peri was a 2025 CES Innovation Award honoree and aims to provide data-driven insights for those experiencing perimenopause.
