How it works

Sign up. Get your box. A minute a morning. Your answer.

Every study works the same way: you use the product on some nights and skip it on others, answer the same few questions each morning, and compare you with you. Here's the mouth tape study, step by step.

Four steps. That's the whole study.

No app, no account, no lab. Real screens from the mouth tape study, with an example tester.

  1. Sign up. Two minutes.

    A few quick questions and a safety check. If a study isn't a safe fit for you, it says so before you pay a thing.

    • No app, no password
    • Safety check built in

  2. Your box arrives. The product is free.

    The tape is yours to keep. You cover $6.95 shipping, and we email you when it's on the way.

    • Yours to keep
    • $6.95 shipping

  3. Use it some days. Skip it on others.

    That's the whole trick: you compare you with you. An evening email says what kind of night it is. Each morning, a few taps, about a minute. Miss one? It's added at the end.

    1. Night 1Without
    2. Night 2With it
    3. Night 3With it
    4. Night 4Without
    5. Night 5Without
    6. Night 6With it
    • About a minute a day
    • Email reminders
    • Phone nudges, if you want them

  4. Get your answer. Yours, side by side.

    Your nights with it and without it, side by side, in plain words. Plus how your guess held up, and what your tracker saw if you wear one.

    • A plain-words verdict

Who it's for. Checked before you pay.

Every study starts with a short safety check. Your answers are checked on your own device, and we only learn whether the study is a fit. Here's the mouth tape study's.

Not a fit if any of these apply

  • You're under 18
  • Diagnosed sleep apnea, or another diagnosed sleep disorder
  • Your nose is often blocked, or it's hard to breathe through it
  • You already tape your mouth at night
  • Acid reflux at night
  • A lung condition, like COPD or asthma
  • An allergy to adhesives or tape
  • Panic or anxiety when your mouth is covered
  • You're pregnant

A few questions about your sleep

  • Do you snore loudly, loud enough to hear through a closed door?
  • Do you often feel tired or sleepy during the day?
  • Has anyone seen you stop breathing or choke in your sleep?
  • Do you have, or take medicine for, high blood pressure?
  • Is your BMI over 35?
  • Are you over 50?
  • Is your neck size over 16 inches (40 cm)?
  • Were you assigned male at birth?

If 5 or more are a yes, this study isn't a fit.

If a study isn't a fit, the check says so before you pay anything. It doesn't say anything about your health, only that this study isn't the right one for you.

Sleep is where we started. Not where we stop.

Every study sets its own plan: what you use, what you track, and for how long. The way you get your answer stays the same.
