SomniSense · Sleep Apnea Detector
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.

Sound-based wellness monitoring. Not a diagnosis or a substitute for a sleep test.
Your questions. Your own night.
Find out whether you snore, what it sounds like, and when and how often it appears. Snoring detection, playback and saving of available audio stay free, with a separate record from breathing irregularities.
Explore your snoring record →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.
Explore breathing detection →Hear what your breathing sounded like around a possible irregularity, without searching through the whole night. Open a marked moment to follow its waveform and available sound before and after; no wearable connection is required.
See a marked moment with sound →Find out how often breathing irregularities were detected and whether they clustered at particular times. Your whole-night report shows the count, timing and Breathing Irregularity Index (BRI), then lets you choose a moment to review. BRI is not a clinical severity grade.
Walk through a real morning report →Add an optional tag before recording to note an evening drink or a stressful day. With Pro, compare nights with and without that tag, see how many nights are in each group, and look for differences in your own readings.
Compare habits and nights →Trying another sleep position or pillow? Keep that choice with your records and use Pro’s later complete breathing irregularities reports to see whether the pattern repeats across nights.

The value of coming back
Compare a night that stood out with your other recordings. If you tagged a change before bed, look for similar differences on later nights. Breathing and snoring have separate readings, so you can follow each over time.
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.
A real founder record and illustrative scenarios
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 the three-night story →Imagine sleeping eight hours but still feeling tired. A breathing record gives you something concrete to review alongside how you feel: open the marked moments and available sound, then see how different nights compare if you choose to continue. Optional tags can keep an existing routine with each recording. This illustrative scenario describes a way to use the app, not a reported user outcome.
If a glass of wine is already part of some evenings, an optional tag chosen before recording can keep that context with your night. With Pro and enough observations, compare tagged and untagged nights and revisit the marked moments behind the readings. This illustrative scenario does not report a user result or show that wine caused a change.
The founder’s account is his own use of SomniSense. The other two cards are illustrative scenarios, not user testimonials.
With SomniSense, review marked moments with sound, then compare your own nights over time.

Our research. Your evidence.
We develop our own sound-analysis algorithms. Our models are trained and tested on recordings annotated through PSG sleep studies. Our public research papers share the methods and test results behind phone-based breathing analysis.
Our on-device acoustic technology is the subject of three U.S. provisional patent applications. In the app, go from your whole-night result to the marked moment, waveform and available sound you can check for yourself.
Read the evidence →Audio and waveforms stay local, with no cloud recovery. Account and recording results sync for services such as email reports. Exported sound copies are yours to manage.
Read the privacy policy →Have symptoms or a partner who notices pauses or gasping? Speak with a qualified health professional, even if your recording contains no marks. SomniSense analyzes sound; a clinical sleep test measures additional signals such as airflow and blood oxygen.
Understand clinical sleep tests →Hundreds took part in our early experiments. Explore the work behind the app, then see the kind of result you can get: a real night report and original sound you can check for yourself.
Begin with your own night
Put your phone by your bed and review your own night after sleep. Your first complete breathing irregularities report is free to view—and stays free to revisit. No valid report yet? You can try again for free.
Recording and analysis stay free. Pro unlocks later complete breathing irregularities reports; snoring stays free.
Your first complete report is free when a recording shows more than 30 minutes of sleep and detected snoring. Reports before that qualifying recording, and the qualifying report itself, stay free to view. If a recording fails, shows 30 minutes of sleep or less, or detects no snoring, you can try again free. A qualifying report still counts if no breathing irregularities are marked. Even if no snoring or breathing irregularities are detected, the recording cannot rule out sleep apnea.
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.
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.
