How to find out if you snore (no smartwatch needed)

By Naresh Singh · 28 October 2026 · 6 min read

Snoring is one of those things you can't easily check for yourself. You're asleep when it happens, and by morning there's nothing to show for it except, perhaps, a tired partner or a dry throat. The good news is that you don't need a sleep lab or a smartwatch to get a clear answer. A few nights of simple observation will usually tell you whether you snore, roughly how often, and whether it's worth a conversation with a doctor.

1. Ask someone who's heard you

The quickest route is to ask whoever shares your room, or anyone who has slept nearby on a trip or a sofa bed. Be specific with your questions, because "do I snore?" tends to get a vague answer. Try these instead:

• Is it every night, or only some nights?
• Is it soft and steady, or loud enough to wake you?
• Does it happen when I'm on my back, or in any position?
• Have you ever noticed me stop breathing for a moment, then gasp or snort?

The last question matters most, and we'll come back to it. A partner's account is useful, but it has limits: they're usually asleep for much of the night too, and memories of a noisy night tend to blur together. That's where recording helps.

2. Record yourself with your phone

Your iPhone's microphone is perfectly capable of picking up snoring from across a nightstand. Whether you use a voice recorder or a dedicated sleep app, a little setup makes the recording far more useful.

Where to put the phone

• On the nightstand, not the bed. A phone on the mattress or under a pillow picks up rustling sheets and every movement, and it can get warm while charging.
• Within about an arm's length of your head. Close enough to catch quieter snoring, far enough to stay out of the way.
• Microphone facing you and uncovered. Avoid propping it behind a lamp, a glass or a stack of books.
• Plugged in. An overnight recording uses battery, so charge while you sleep.

Set up the room

• Turn on Do Not Disturb (or a Sleep Focus) so notifications don't light up the screen or buzz, but make sure your alarm is still allowed to sound.
• Reduce steady background noise if you can. A loud fan, air purifier or white-noise machine can mask quieter snoring.
• Record more than one night. Snoring often varies from night to night, so a single recording can mislead you in either direction. Three to five nights, including a weekend, gives a fairer picture.

A plain voice recorder works, but scrubbing through seven or eight hours of audio is tedious. Apps built for this pick out the moments that sound like snoring and save just those, so you can listen in a couple of minutes over breakfast.

3. Make sure it's you, not a partner or pet

If you share a bed, or a dog sleeps at your feet, a recording may capture someone else's snoring. Before you draw conclusions, listen to a handful of clips across several nights and ask yourself:

• Which direction is it coming from? The snorer closest to the phone will sound loudest and clearest. Try putting the phone on your side of the bed one night and on your partner's side the next.
• Does it change when you do? If the sound stops or shifts when you rolled over, or when you got up, it's probably yours.
• Is it there when they're not? A night when your partner is away, or the dog sleeps elsewhere, is a natural experiment.
• Does it sound like you? People tend to recognise their own breathing once they've heard a few clips, even if it's an unwelcome surprise.

4. Things often linked with snoring

Snoring happens when the soft tissues in the throat and nose vibrate as air moves past them. Many things can make that more likely on a given night. If your recordings show snoring on some nights but not others, these are worth comparing against what was different:

• Sleeping on your back. Many people snore more on their back than on their side, as the tongue and soft palate can fall back slightly.
• Alcohol close to bedtime. Alcohol relaxes muscles, including those in the throat, and some people notice they snore more after an evening drink.
• A blocked or stuffy nose. Colds, allergies and congestion can push you into breathing through your mouth, which often comes with snoring.
• Sleep position and pillows. A pillow that tips your head forward or back changes the shape of your airway, and so can sleeping curled up or flat out.
• Being very tired. After short or broken nights, some people find they sleep more heavily and snore more.

Keeping a one-line note each evening (drink or not, stuffy or not, which position you fell asleep in) makes it much easier to spot your own patterns. Small changes, such as trying to sleep on your side or having your last drink earlier, are reasonable things to experiment with, but they don't work for everyone, and they're no substitute for medical advice if something worries you.

5. When to see a doctor

Occasional, gentle snoring without any of these signs is very common and often harmless. But if you're unsure, it's always reasonable to ask.

6. How DreamWave can help

DreamWave is an iPhone app I built to make the recording step painless. Put your phone on the nightstand, start tracking, and go to sleep. Using Apple's on-device sound classifier, it listens for snoring and saves short clips. In the morning you can:

• Play back clips to hear exactly what happened, and when
• See your nightly snore count, a 7-day trend and an intensity timeline
• Check your sleep score, how long you slept, and when you fell asleep and woke

You don't need an Apple Watch. Everything is processed on your iPhone: there's no account, the audio never leaves your device, and you can delete clips at any time. DreamWave doesn't diagnose anything; it simply helps you hear what's going on so you can decide what to do next.
