Fibra is the only wearable that continuously measures reproductive health signals directly from the source, not inferred, not estimated.
Backed by science. Built for women.
Fibra continuously measures key reproductive biomarkers directly from the source, so you can
understand your body with more in depth insights
Vaginal pH
Detect meaningful changes earlier.
Every pH shift tells a story about your cycle, vaginal health and reproductive wellbeing.
Discharge
Understand your cycle with more confidence.
Follow discharge patterns to help you identify fertile windows, hormonal shifts, and reproductive transitions.
Temperature
Reveal personalized patterns.
Small temperature changes reveal bigger patterns related to ovulation, PMS menopause, and changing hormone levels.
Heart Rate
See how your body responds.
Heart rate changes provide insight into stress, recovery, cycle phases, and reproductive transitions.
Heart Rate Variability
Understand your resilience and wellbeing.
See how your body adapts beneath the surface to stress, recovery, and reproductive changes.
Most wearables can only estimate what’s happening inside your reproductive system. Fibra is the first solution to measure directly from the source, bringing your reproductive system into the complete picture of your health.
