Snore Signals

Put your iPhone on the nightstand and go to sleep. In the morning, see exactly when you snored, how loud it was, and what your heart rate was doing. Tap any snore to hear it.

Snore Signals isn't a score out of a hundred. It's your actual night, second by second.

ON-DEVICE SNORE DETECTION Apple's built-in sound classifier listens through your recording on your iPhone and marks every stretch of snoring, with how confident it is about each one. Nothing is uploaded.

A TIMELINE YOU CAN HEAR • Your night's real loudness as a waveform • Tap any snore to play it from just before it started • Sort by loudest, and relabel anything that wasn't snoring

HOW LOUD, IN DECIBELS Every snore gets an estimated peak level in dB and a Light, Moderate or Loud rating, plus a breakdown of how your night split between them.

HEART RATE WITH APPLE WATCH While you record, the Snore Signals Watch app measures your heart rate every few seconds instead of every few minutes. It's drawn under your snoring, with your heart rate during each event.

STAY AWAKE NUDGES Trying not to doze off on the couch or at your desk? Turn on "Nudge me if I doze off" and Snore Signals listens for the steady rhythm of snoring as it records. It usually notices within about 20 seconds, then taps your wrist, vibrates your iPhone and plays a rising chime until you tap I'm awake. Pick which nudges you want. With Apple Watch, the Watch's own microphone does the listening, so it works even with your iPhone in a pocket or bag.

FIND WHAT ACTUALLY HELPS Tag what you tried each night, like side sleeping, nasal strips or skipping alcohol, and see how much you snored on nights you did versus nights you didn't.

BUILT FOR THE WHOLE NIGHT • "Safe to lock your phone" once the microphone is confirmed working • System alerts don't interrupt your recording • A call or Siri pauses it without losing anything, and a tap resumes it • A low battery saves your night before the phone dies

PRIVATE BY DESIGN No account, no server, no ads, no tracking. Your recordings, snoring and heart-rate data stay on your iPhone. Delete everything at any time with one tap.
