Hear your own snoring.
Find out whether you snore, what it sounds like, and when and how often it appears. Snoring has its own record, separate from breathing irregularities.

Do you know whether you snore—and what it sounds like?
Do you know whether your breathing pauses while you sleep?
Do you know what a breathing disturbance sounds like, beyond a wearable reading?
Do you know how often your breathing becomes irregular?
Do you know which habits go with changes in your breathing?
Do you know whether your nighttime breathing differs after a change you’ve tried?
Put your phone by your bed. SomniSense detects signs of possible breathing pauses and shallow breathing in the overnight audio. In the morning, see how many possible irregularities were marked and when they appeared, then open a moment to hear the surrounding sound—without listening through the whole night.
Use your existing compatible phone. No extra device to buy or wear.
Your first complete breathing report is free to view—and stays free to revisit.

Find signs of pauses and shallow breathing.
SomniSense analyzes your overnight phone audio and marks possible breathing pauses and shallow-breathing patterns. See your whole-night result, then choose a moment to examine. These are acoustic observations, not a sleep-apnea diagnosis.
Explore breathing detection →Go beyond a reading. Hear the moment.
Your phone’s independent recording adds something you can review: marked moments, a waveform, and available sounds before and after. Open a moment and save an available clip; no wearable connection is required.
See a marked moment with sound →See how often—and when—it happens.
See the number of marked patterns, their estimated timing and duration, and your Breathing Irregularity Index (BRI). Start with the whole night before reviewing individual moments; BRI is not a clinical severity grade.
Walk through a real morning report →Put habits beside your breathing readings.
Optional tags keep an evening drink or stressful day with the night. Pro compares tagged and untagged nights and shows each group’s size, so you can look for differences in your own records.
Compare habits and nights →Follow a change beyond one night.
Trying another sleep position or pillow? Keep that choice with your records and use Pro’s later complete breathing reports to see whether the pattern repeats across nights. An observed difference does not establish its cause.

Version 1.2.0 interface examples, not an interactive demo. The screenshots illustrate different views; they are not a matched clinical comparison.
These are model-estimated acoustic patterns, not confirmed clinical breathing events. A recording can miss events or contain no candidates; no candidates does not rule out sleep apnea.
The value of coming back
Was it one different night—or a change that keeps appearing?
Return to a changed night and compare it with your other recordings. If you chose to tag a bedtime change, see whether the observed difference appears again. Keep breathing and snoring separate.
Keep the dates, nightly patterns and comparisons in one PDF, so you do not have to assemble scattered records yourself.
Observed differences do not establish a cause or show that a treatment worked.

Why we keep a record of our nights
Founder of SomniSense · Three nights from my own records
I used ordinary phones to analyze my sleep breathing with SomniSense’s own methods, developed with audio paired with labels from clinical sleep studies (PSG). My Apple Watch and two phones gave similar-range readings within each night and moved up, then down together across three nights. Now I can go straight to a marked interval and review its sound. The third Pixel recording ended early.
Read this night’s story →John, 45 · Software engineer
John was sleeping eight hours but still felt exhausted during the day. He had put it down to work stress. Over seven consecutive nights, he followed his recordings and saw how much one night could differ from another. He began comparing nights alongside changes in his sleeping position, looking for differences he could follow over time. For your own night, start with one report and review its marks and available sound; comparing further nights is your choice.
Sarah, 38 · Marketing manager
Over 14 days, Sarah compared nights with wine and nights without it. On nights when she drank wine, her Breathing Irregularity Index (BRI) was higher. She also noticed brain fog the next morning and found it harder to concentrate in meetings. This was a personal observation, not proof of the wine’s effect. You can begin with your own report and choose whether to follow a pattern over more nights.
John and Sarah are pseudonyms. The founder’s account is his own use of SomniSense.
With SomniSense, review marked moments with sound, then compare your own nights over time.

What would you like to understand about your nights?

“I already use a watch. What can sound add?”

Research you can inspect
Read the sound-analysis research, the tasks tested and their limitations. A research benchmark is not your personal diagnostic accuracy.
The underlying technology is the subject of three U.S. provisional patent applications. Our openly available research preprints describe the audio-analysis methods, evaluations and limitations.

A few practical questions
When is my free breathing experience used?
It is used by your first completed Breathing report showing more than 30 minutes of sleep and detected snoring. Reports before that qualifying recording and the qualifying report itself remain free. A failed recording, a report showing 30 minutes of sleep or less, or a recording with no detected snoring does not use the experience. A recording with no detected snoring does not rule out a breathing problem. A valid report with no breathing candidates still counts; no candidates does not rule out sleep apnea.
Can I record in a shared bedroom or with CPAP?
A bedside phone can capture another sleeper or room and equipment sounds. Place it closer to the person being recorded and review the surrounding sound. SomniSense cannot reliably separate two sleepers or confirm whose sound was captured. Performance with CPAP sound has not been established; do not use this record to judge treatment or change therapy. Two recording apps may compete for microphone access, so simultaneous recording is not guaranteed.
What stays on my phone, and what is synced?
Your audio and waveforms stay on your phone. SomniSense does not provide cloud recovery for them. Account information, access status and recording results are synced as described in the Privacy Policy, including results used for email reports. Audio leaves the phone only when you choose to export or share it. Copies saved outside the app are managed by you.
