How Sleep Stage Estimation Works

The app estimates sleep stages by analyzing audio patterns. Unlike medical devices measuring brain activity, this uses acoustic signals to infer sleep depth.

1. Breathing Regularity: Deep sleep has slow, steady breathing. Higher regularity suggests deeper sleep.

2. Breathing Rate: Breathing slows in deeper stages. The app tracks changes relative to your baseline.

3. Movement Detection: Rustling or position changes suggest lighter sleep. Stillness supports deeper classification.

4. Snoring Patterns: Steady, rhythmic snoring accompanies deeper sleep. Irregular snoring may indicate transitions.

Disclaimer: Estimates are based on acoustic patterns only, not equivalent to clinical polysomnography. For personal insight only, not diagnosis. Consult a sleep specialist for medical concerns.


How Breathing Disruption Detection Works

A Breathing Disruption is flagged when three conditions are met:

1. Breathing Context: The minute before contains natural breathing sounds.

2. Significant Silence: Near-complete silence for 10+ seconds.

3. Sudden Recovery: Silence broken by a loud snore exceeding the noise floor.

Disclaimer: Acoustic analysis only. Not a medical device. Consult a healthcare professional for diagnosis or treatment.
