Sawmill
STOP-BANG + Partner Observations

Score your snoring. Spot the danger.

A free 60-second screener that combines the validated STOP-BANG sleep apnea questionnaire with what your partner actually hears at 3am. You'll get a clear risk score and a recommended next step — not another graph.

⏱ ~60 seconds 🔒 No account 📋 Doctor-ready summary
Not medical advice. Sawmill is an educational screener based on validated questionnaires. It is not a diagnosis, not a substitute for a sleep study, and not a substitute for your physician. If you or your partner suspect sleep apnea — especially with witnessed pauses in breathing — please consult a sleep specialist.

About this screener

Sawmill combines two validated, peer-reviewed screeners: the STOP-BANG questionnaire (American Academy of Sleep Medicine) and a 5-item subset of the Epworth Sleepiness Scale. The risk score is computed by rule, not by AI guesswork — only the explanation text is generated. We never store your responses unless you opt in by saving them with your email.
