Works offline. Never uses your data. Saves you a $1,000 sleep study — know your risk in 2 minutes.
An estimated 80% of moderate-to-severe sleep apnea cases go undiagnosed. Sleep studies cost $1,000 or more. Most people wait years — or never get checked at all.
A formal sleep study (polysomnography) costs $1,000–$5,000. Insurance coverage is inconsistent. Most people never access it.
Average time from symptom onset to sleep apnea diagnosis is 6–7 years. Unmanaged OSA contributes to hypertension, heart disease, and stroke.
Most patients don't bring up sleep issues at primary care visits. They don't know the warning signs. They don't know the right questions to ask.
The Axion Sleep Apnea Screener puts two clinically validated tools in your pocket — the STOP-BANG questionnaire and Mallampati throat classification — with on-device analysis and a PDF you can show your doctor.
The gold-standard 8-question screening tool used in clinical practice. Validated for obstructive sleep apnea risk stratification. Takes under 60 seconds.
Self-guided throat classification used by anesthesiologists and sleep specialists. Class III/IV scores correlate with higher OSA risk.
Combined scoring across both assessments. Clear Low / Moderate / High risk classification — runs fully on-device, so it never touches your data plan.
Export a formatted clinical summary with your STOP-BANG score, Mallampati class, risk category, and recommended next steps. Hand it to your doctor.
No account. No sign-up. Never touches your data plan — no airtime used. Works on entry-level Android phones that millions of people already own.
Full screening, scoring, and PDF generation works without any internet connection. Built for the real world — clinics, rural areas, anywhere.
No appointments. No labs. No waiting. Start in 30 seconds.
Complete the STOP-BANG questionnaire. Simple yes/no questions about snoring, tiredness, and physical traits. Under 60 seconds.

See your combined risk score instantly. Export a shareable clinical PDF to discuss with your doctor at your next visit.
Screen yourself for free. Use Sparks when you need a shareable clinical PDF. No subscription. No commitment.
No. This app is an educational screening tool — not a diagnostic device. The STOP-BANG and Mallampati tools are widely used in clinical practice for risk stratification, but a definitive diagnosis of sleep apnea requires a formal sleep study (polysomnography) ordered by a physician. Use this app to start the conversation with your doctor.
Everything runs on your phone. No servers, no accounts, no analytics. No airtime used — the app never touches your data plan. Your answers, scores, and PDFs stay on your device by design.
STOP-BANG is a validated 8-item screening questionnaire developed at the University of Toronto for obstructive sleep apnea (OSA). It stands for: Snoring, Tiredness, Observed apnea, Blood Pressure, BMI, Age, Neck circumference, Gender. Scores of 0–2 indicate low risk; 3–4 moderate risk; 5–8 high risk. It is widely used in pre-surgical screening worldwide.
The Mallampati classification is an airway assessment developed by Dr. Seshagiri Mallampati that grades throat anatomy on a scale of Class I–IV based on how much of the soft palate, uvula, and tonsils are visible when you open your mouth. Class III and IV are associated with increased risk of OSA. The app guides you through the self-assessment with visual reference images.
