Your hormones move. Your lab test doesn’t.

Qyn is building an at-home device that measures hormone levels from a small drop of blood, helping you see how they change over time — not just in a single lab visit.

Connect what you take, what's measured, and how you feel.

Blood is already how clinicians measure many of your hormones. Now, Qyn brings that measurement home. It connects your hormone levels with your dose, how you feel, and the data you already track, from sleep and HRV to activity, recovery, and more.

Instead of seeing each piece on its own, Qyn brings it all together in one place so you can spot connections over time and share a clearer picture with your clinician.

No new ring. No new watch. Just a deeper view of your data. 

how it works

Step 1

Collect a small blood sample at home

Step 2

Qyn measures your hormone level

Step 3

See your readings build into a pattern in the app.

Same woman. Different days. Different hormone levels.

One lab draw can tell you what was true that day. Repeat measurements can show what changed before, what happens next, and what’s normal for you.

Frequently asked questions

What exactly is Qyn?

Qyn is an at-home hormone measurement system in development. The device is designed to measure hormone levels from a small blood sample, while the app helps you see how those readings change over time and relate to symptoms, therapy, and health metrics you already track.

When will Qyn be available?

Qyn is currently in early access. We’re inviting a limited number of people to be among the first to experience it and help shape what comes next.

Is this difficult to use?

No. QYN is designed to be simple, fast, and easy to use at home — without adding complexity to your routine.

Can I share this with my doctor?

Yes. QYN is designed to complement the care you’re already receiving — not replace it. By giving you a clearer picture of your hormone patterns, it can help support more informed conversations and decisions.

What if I’ve already had my hormones tested?

You’re not alone. Many women have had labs done — and still don’t feel like they have clear answers. That’s because most testing doesn’t capture how hormones change over time. QYN fills in that missing context.

Is this only for women on hormone therapy?

Not at all. QYN is designed for women who are noticing changes in their body — whether you’re exploring options, working with a doctor, or already trying something. It gives you visibility into what’s actually happening, regardless of where you are in your journey.

What’s the long-term vision for Qyn?

Qyn is designed to become an intelligence layer between biology and decision-making — empowering individuals, supporting researchers, and enabling partners across health, performance, and longevity to better understand how biology changes over time.

What problem does Qyn solve that isn’t being solved today?

Today, hormonal data is sparse, fragmented, and reactive. Qyn introduces continuity, context, and personalization — helping people understand trends over time rather than relying on occasional snapshots or generalized “normal” ranges.

Who is Qyn for?

Qyn is built for individuals who care about understanding their biology — from athletes and high-performers to people navigating health transitions, longevity, or optimization. The platform is intentionally non-gendered and designed to scale across use cases over time.

Is QYN a medical device?

QYN is being developed as a health intelligence platform focused on insight and understanding, not diagnosis or treatment. The system is designed to complement — not replace — clinical care, while opening the door to future integrations across research, performance, and preventative health.

How is this different from a standard hormone test?

Most hormone tests give you a single snapshot — one moment in time. But hormones don’t stay the same. They fluctuate throughout the day, across weeks, and in response to stress, sleep, and lifestyle. QYN helps you see those patterns over time — so you’re not making decisions based on one isolated number.

Why focus on hormones?

Hormones act as the body’s regulatory system — influencing energy, mood, recovery, metabolism, stress response, and long-term health. Despite their impact, hormonal insight today is largely reactive, infrequent, and inaccessible. QYN exists to make this foundational layer of biology measurable, understandable, and actionable over time.

Meet Qyn

Qyn is building a new way to understand hormones through blood-based measurement, meaningful patterns, and better context over time — helping people see what’s changing in their bodies and make more informed decisions about their health.
