Sawmill
An estimated 30 million Americans have undiagnosed sleep apnea. Sawmill is a free 60-second screener built on the validated STOP-BANG questionnaire plus partner observations — paired with a printable bedside journal you can hand to your doctor.
"My wife says I stop breathing for like 10 seconds at a time. Is that bad? I'm too embarrassed to ask my doctor."
"SnoreLab said I snore 76% of the night. So what?"
"My partner is keeping a journal and showing me. Worst feeling I've ever had."
There are dozens of sleep tracking apps. None of them give you a clear answer.
Sawmill does.
Walk through the validated STOP-BANG questionnaire and a 5-item daytime sleepiness check. Add what your partner actually hears. Get a 0–100 risk score and a clear recommended next step in 60 seconds.
Try the analyzer →A free printable 7-day card pack your partner keeps on the nightstand. Six checkboxes per night: snore volume, witnessed pauses, gasping, morning headache. Becomes the data your doctor actually wants.
Get the journal →The American Academy of Sleep Medicine's standard screener. 8 yes/no items. A score ≥3 has 84% sensitivity for moderate-to-severe OSA.
Daytime sleepiness scale (Johns MW, Sleep, 1991). We use 5 items. ≥11 indicates excessive sleepiness — a key OSA marker.
The single most predictive item is witnessed pauses in breathing. We weight it accordingly — it's the question your doctor will ask first.
Your risk score is computed by rule, not by AI guesswork. Gemini only writes the plain-language explanation. The number is deterministic.
If a 7-day journal is enough, you'll never pay us a cent.
No. Sawmill is an educational screener built on validated questionnaires. It is not a substitute for a sleep study or your doctor. If your screener returns High or Severe — or you marked witnessed pauses in breathing — please contact a sleep specialist.
No. Your risk score is computed by deterministic rule (STOP-BANG ≥3 = intermediate, ≥5 = high; Epworth ≥11 = excessive; witnessed apnea adds a weighted boost). The AI only generates the plain-language explanation. Same answers in = same number out.
No. Sawmill is a website. The journal is a PDF you print from your home printer. No download, no account.
Yes — STOP-BANG and Epworth are the same screeners they use. Bring the doctor-ready summary plus a week of journal entries and you're giving them more data than most patients ever do.
Because that's what your partner says you sound like. We chose the name because it's the actual phrase people use when describing the snoring they're worried about.
