NIGHTTIME BREATHING, OVER TIME
See what happens to your breathing while you sleep — and how it changes over time.
SomniSense shows when breathing patterns changed, lets you review what happened, and helps you compare nights when you tried something different.
Review candidate type, time, model-estimated duration, marked waveform, available audio, and the event's position in the whole night — using the phone by your bed.

Methodology and limits →START WITH YOUR QUESTION
What brought you here tonight?
Choose the situation that sounds closest. Each guide explains what a phone recording can add, what it cannot determine, and what you can review tomorrow.
I want to record my snoring
See when snoring appeared, how it changed through the night, and what audio is available to review.
Open this guide →My partner says I snore
Turn a difficult conversation into one night you can review together.
Open this guide →I wake up gasping
Add calm, non-diagnostic context to a symptom that deserves attention.
Open this guide →I sleep enough but still feel tired
Look beyond hours in bed and begin a multi-night record without assuming the cause.
Open this guide →I already have a score or alert
Add a separate, reviewable acoustic record without replacing your watch or ring.
Open this guide →I am trying one change
Tag the nights, compare repeated observations, and keep association separate from cause.

A deeper view of nighttime breathing
Start with the whole night. Then move to the hour, the minute, the waveform and the candidate region worth reviewing. If audio is available, play it back.
- 1
See where the night changed
The whole-night and hourly views show when detected breathing patterns clustered instead of hiding them inside one nightly number.
- 2
Go back to the minute
Open the selected minute, inspect its real waveform and see the regions the acoustic model flagged.
- 3
Review the candidate region in context
See the model-estimated time, duration and pattern label. When audio is still available on the phone, tap play and hear what the microphone captured.

ACROSS NIGHTS
One night is an observation. Several nights become your baseline.
Night-to-night variation is normal. Trends keep the sample count, recording coverage and recent history visible so a single rough night does not become the whole story.
Use the 7-day view first. Longer 30- and 90-day windows are there when enough nights have accumulated to make the comparison worth reading.
See how Trends works → WHEN YOU TRY SOMETHING DIFFERENT
Does the same change keep showing up?
Tag a clear factor before bed — side sleeping, alcohol, an elevated head, a nasal strip or another change you want to observe. SomniSense compares tagged and untagged nights once both groups have enough data.
The result is an observation, not a verdict. It shows what was associated with higher or lower readings in your nights; it cannot prove what caused the gap.
KEEP THE EVIDENCE
A report is the product delivery, not an export afterthought.
SomniSense keeps the first-morning Night Report separate from longer-period structured reports. The latter organize candidate events, multi-night patterns, tagged-night observations, coverage, method and limits for saving, review, or sharing.

USE IT WITH WHAT YOU ALREADY HAVE
Already have a score or alert? Add the audio regions behind the night.
A watch or ring can raise the question with its own sensors. SomniSense adds a reviewable acoustic layer — from the whole night, to the minute, to the seconds worth reviewing. Use the phone already beside your bed; neither view replaces PSG, HSAT or professional assessment.
Everything SomniSense helps you follow
The screens above are the main path. These eight parts make the path useful night after night.
Breathing evidence
Whole night to selected minute
Move from the overnight pattern to hourly distribution, a selected minute, its waveform and highlighted acoustic regions.
See & Hear
Review available audio on device
Open a detected minute and play the locally stored audio while it remains available on your phone.
Event timeline
Keep time, duration and context together
Review detected events in sequence instead of trying to infer the night from one summary score.
Trends
Build a personal multi-night baseline
Compare nights with the sample count and recording coverage visible across 7-, 30- and 90-day windows.
Lifestyle Lab™
Tagged versus untagged nights
Observe whether a repeated difference is associated with the nights when you tagged a particular factor.
Reports
Structured evidence with limits attached
Keep single-night facts, trends, factor comparisons, methods and boundaries together in a shareable wellness summary.
Snoring, separately
SRI, loudness and sound texture
Follow snoring as its own evidence stream rather than mixing it into the breathing view or a single total sleep score.
Validation
Task, cohort and limits stated
Read the model results with their exact task, denominator and comparison against PSG reference annotations.
HOW WE VALIDATE IT
Validated in parts, with the limits stated.
Across n=80 paired PSG nights, the published benchmarks report 94.29% accuracy for 1-second snore-segment classification and 88.49% accuracy for 200-second breathing-window classification. Those are different tasks. Neither number turns phone audio into airflow, oxygen, breathing effort, EEG or a diagnosis.
LEARN BEFORE YOU DOWNLOAD
Start with the question you still have.
SomniSense is easier to trust when you can see what a phone can measure, what stays private and what BRI does—and does not—mean.
