AUSTRALIA's First Women's Smart Ring

Designed for accurate cycle-tracking.

Meet the Basal Body Ring

Revolutionary smart ring designed specifically for women to improve menstrual cycle tracking. The BBRing goes beyond standard cycle tracking to assess stress physiology and overall body health. It monitors basal body temperature, heart rate and heart rate variability while you sleep. Syncing with the Cycle Tracker app each morning, it helps with fertility tracking, training, body literacy and breastfeeding monitoring.
