Find signs of breathing pauses. Check them for yourself.

From a number to a moment you can examine.

Find the marked moment you want to understand.

See the estimated time, duration and type of each marked breathing pattern, with BRI as your nightly summary.

Check the sound around it.

For a pause-like mark, follow the sound before the quiet interval and after it returns. The waveform and moving pointer help you keep your place.

See whether it appears again.

Keep later nights to find out whether a similar pattern repeats in your own record. Pro unlocks later complete breathing reports.

What the app can surface

SomniSense groups candidate acoustic patterns into two product labels:

• Pause-like patterns — an acoustic interval that resembles a sustained interruption in the recorded breathing pattern.
• Shallow-breathing-like patterns — a quieter or reduced acoustic pattern that the model marks for review.

These labels describe model output from phone audio. They do not establish airflow reduction, oxygen desaturation, arousal, airway anatomy, or a clinical apnea/hypopnea event.

What you can review in the morning

• Candidate pattern counts from the overnight audio analysis
• BRI for the night — product-defined events per estimated sleep hour
• Time-organized event list with model-estimated start time, duration, and type
• Selected local audio playback so you can inspect the underlying recording
• Multi-night trends to compare your own pattern over time

Our own research. Your own record to review.

Our audio models were developed using sleep audio paired with PSG study labels. The published compressed-model study reports 88.49% accuracy and 88.06% F1 on labeled 200-second breathing windows. In the app, you can return to the marked moment and inspect the available sound for yourself.

The study result describes window classification, not the accuracy of every app event or personal result. Phone-audio marks and BRI do not measure clinical AHI or diagnose sleep apnea. A report without marked candidates does not rule out sleep apnea.

How to read BRI

Use BRI to compare your own nights under reasonably similar recording conditions. It is a wellness-monitoring index, not a clinical severity score, and clinical AHI thresholds should not be applied to it.

A persistent or concerning pattern can help you describe what you observed when speaking with a qualified clinician. Symptoms or urgent concerns should be evaluated medically regardless of what the app reports.

What this is not

• Not a diagnosis of obstructive sleep apnea (OSA). OSA diagnosis needs in-lab PSG or Type-III HSAT plus a sleep specialist's evaluation.
• Not validated for users under 18.
• Not a substitute for your CPAP's compliance report. If you're on CPAP, that machine's data is more authoritative for treatment decisions.

What it is: a wellness tool that organizes acoustic observations over time, so you can notice changes and decide whether to discuss them with a qualified clinician.
