While you wear them, the sensors continuously read five reproductive signals — no action needed from you.

Quick answers
The short version.
Apps predict from dates you enter and symptoms you log. Femora reads five physiological signals directly from your body — continuously and passively — so its insights follow your body even when your cycle doesn't follow a template.
OPKs give you a single-day snapshot and require precise timing. Femora builds a continuous picture across your cycle, catching shifts that strips can miss — with zero daily testing.
Wrist wearables estimate cycles from wrist-level signals. Femora measures at the source — skin temperature, heart rate, HRV, discharge and pH from the fabric itself — for signals that are closer, richer, and more specific.
Femora was built with irregular cycles in mind. Instead of assuming a 28-day template, it looks for your personal patterns and updates as they change. It's a wellness insight tool — it doesn't diagnose or treat PCOS.
In pilot wear, sensor readings matched reference measurements closely even with 2–3 missed wear days per month. Femora shows trends and patterns — it's designed for insight, not medical diagnosis.

Trusted by experts
The people who support women's health, backing Femora.
Fertility is a puzzle with many pieces — stress, sleep, nutrition, timing. A wearable that reads signals continuously instead of asking women to log them is the direction the field needs.
Dr. Amara Osei
Naturopathic Doctor, Integrative Fertility Care
My clients are exhausted by tracking. When they can simply wear something and still see their patterns, adherence changes completely — and so does the conversation we have in session.
Teresa Alvarez, RHN
Fertility Nutritionist, Live Well Nutrition
Temperature alone tells a fraction of the story. Combining skin temperature, heart rate, HRV and discharge patterns is what makes cycle interpretation genuinely personal.
Dr. Lena Forgacs
Reproductive Health Researcher
The most exciting thing about Femora is the sense of control it gives women back. Understanding your own data is empowering in a way a prescription pad can't be.
Dr. Parvaneh Saidi, MD
CEO & Co-founder, Elan Women's Health
So many of the women we support feel blindsided by their own cycles. Tools that make patterns visible earlier give them time — and time is everything on this journey.
Isabelle Fontaine
Executive Director, Fertility Friends Foundation
As a fertility support network, we see the emotional cost of uncertainty daily. Continuous, passive insight is not a luxury — it's compassionate design.
