Your phone, your bed, your data — nothing else.

SomniSense runs entirely on your device. No cloud upload. No wearables. No clinic visit. Here's exactly what happens between you tapping start and your morning report.

TL;DR

SomniSense uses on-device AI to detect snoring and breathing irregularities from microphone audio. Audio never leaves your phone. The AI runs every night while you sleep, produces a Breathing Irregularity Index (BRI) score the next morning, and lets you play back any event you want to verify. Validated against in-lab PSG (n=70+).

5 steps from tag to report

Step 1 — Tag tonight — is the part no other consumer sleep app does. It's also what makes Lifestyle Lab™ work.

  1. 1 🧪

    Tag tonight (30 seconds)

    Before bed, tap what is true tonight: alcohol, side-sleep, anti-snore pillow, late caffeine, large meal. Tags become YOUR data. Lifestyle Lab™ uses these tags to compute Factor Impact for YOU.

  2. 2 📱

    Place your phone

    On a stable nightstand, 50–90 cm from your head, microphone facing you. Plugged in, Do Not Disturb on. No special accessory.

  3. 3 🌙

    Sleep normally

    On-device AI listens for snoring, breathing pauses, reduced breathing. The audio never leaves your phone unless you opt to share it.

  4. 4 📊

    Wake up to your report

    Every event time-stamped, charted, and (press play) listenable as the actual audio. PSG-level event granularity from a smartphone.

  5. 5 📬

    Doctor-Ready Cadence™

    On Pro: every Sunday 7am, a PDF lands in your inbox. Monthly summary on the 1st. Print it. Forward it. Bring it to your next visit.

Why on-device AI

Your sleep audio includes you snoring, your partner breathing, conversations you don't remember. We chose on-device AI because data this personal should never leave the phone unless you ask it to.

On-device also means: no battery drain from constant uploads, no privacy risk from a server breach, no 'we're sorry your account was leaked' email.

Why we'd rather miss than alarm

Our model is precision-first by design. If we can't be confident an event is real, we don't flag it. The trade-off: if your real BRI is 12, we might report 10. But if we report 18, you can trust it's at least 18. False alarms damage trust. Missed borderline events are recoverable — just keep tracking, the trend will surface.
