Fibra

Fibra is a women’s reproductive health technology brand offering smart underwear designed to make cycle tracking more convenient and informative. Its wearable combines fabric sensors with a small detachable electronic unit that collects and securely sends body data to the Fibra app. By monitoring multiple signals—including vaginal pH, discharge patterns, skin temperature, heart rate, and heart rate variability—the system provides personalized insights into cycle changes and likely fertile windows without daily testing or manual logging.

Fibra’s app helps users understand where they may be in their cycle, recognize patterns that are typical for them, and explore how factors such as sleep and activity may relate to changes over time. The underwear is designed for regular wear using soft, breathable fabric; the electronic unit is removed before washing. Fibra describes its approach as non-hormonal and non-invasive, and says its product complies with ISO 10993 and IEC 60601 standards. The company also emphasizes privacy, safety, and comfort, and offers smart underwear and electronic units, including launch promotions and shipping to Canada and the United States.
