Sleep DiplomatDr. Walker is a professor of neuroscience and biomedical engineering, a sleep scientist, and author of the New York Times #1 Bestselling book Why We Sleep. He has spent his career decoding what sleep does to the human brain and body — and why so few of us are getting enough of it. Nightfall is the first platform built from that science, designed to translate decades of research into something you can actually use.
Frequently asked questions
Your wearable measures. Nightfall IQ interprets. It's the intelligence layer that sits on top of the data your ring or band already collects — analyzing months of nights at once to find patterns a single nightly summary can't show, then translating them into a plan calibrated to your own biology. Think of your wearable as the sensor and Nightfall IQ as the analyst reading it.
Not for Nightfall MD — you can book a physician consultation with or without one. But connecting a wearable to Nightfall IQ gives our models real signal to work with, and gives your physician a fuller picture before your first visit. We currently support Oura and WHOOP, with more integrations on the way.
Nightfall MD is a direct-pay telehealth service, so it works outside the traditional insurance system, and that's by design. Typical insurance often means long waits to see a sleep physician, sometimes months, while your sleep problems keep affecting your daily life. Skipping insurance means faster access to care, no referrals or prior authorizations, and more privacy since nothing about your condition gets shared with an insurance company.
HSA and FSA funds can often be used to cover the cost. We'd recommend checking with your plan administrator to confirm eligibility, since rules vary by plan.
Yes. We will never sell your health data to advertisers or data brokers — that's a founding principle, not a policy footnote. Your data is encrypted at rest and in transit, used only to generate your insights and, if you use Nightfall MD, shared with your treating physician — and you can request full deletion at any time.
Most of our members know something is off with their sleep but haven't been able to pinpoint what — chronic fatigue, restless nights, a recovery score that never seems to move. Nightfall IQ is built for that. And if what you're dealing with is more serious than data alone can fix, Nightfall MD connects you directly to a licensed physician rather than leaving you with just a report.
We're currently in closed alpha, with limited, invitation-based access while we refine the product alongside a small group of early members. Join the waitlist and we'll reach out as space opens — alpha members get direct input into what we build next.
