The Snore Detection App That Stays on Your iPhone

Snollo classifies snoring, breathing, coughing, and sleep talking on your iPhone — and saves short clips so you can hear exactly what your nights sound like.

Unlike SnoreLab and Sleep Cycle, Snollo classifies bedroom audio on your iPhone — what gets saved goes to your own iCloud, under your Apple ID. Free to download; snore detection included on the free tier.

What a snore detection app should actually do

Classify, don't just record

Recording 8 hours of audio gets you a haystack. A useful snore detection app classifies sounds in real time — so by morning, you have a timeline of snore events, not raw audio you'd never listen through.

Let you play the clips back

Reading 'you snored 47 times' is abstract. Hearing one of the actual snores tells you immediately whether it's the loud, sleep-apnea-suggestive kind or the soft kind that's barely worth tracking. Snollo saves short clips, free tier included.

Show intensity over time, not just counts

Snoring isn't binary. A useful app shows snore intensity throughout the night, so you can see whether it gets worse when you sleep on your back, after wine, or in certain phases of the night. Patterns are how you find what helps.

Keep your bedroom audio out of the cloud

Many snore apps upload your audio to their servers for processing. Snollo classifies the audio on your iPhone instead, and the clips you save go to your own iCloud — under your Apple ID, across the Apple devices you sign into. For the most intimate audio any app could collect, that's the right default.

What Snollo detects

Snollo's on-device model is trained to classify several distinct nighttime sound categories. Each detected event gets a timestamp, a confidence score, and a short playback clip.

Snoring. The main event. Loud, irregular, or persistent snoring is the strongest signal for sleep apnea risk.
Breathing patterns. Regular breathing versus pauses or irregular rhythm — relevant for spotting potential breathing-related sleep disturbances.
Coughing. Frequent coughing during sleep is often missed in self-reports but obvious in a timeline view.
Sleep talking. Captured as a separate category so you can play it back the next day — sometimes funny, sometimes informative about stress.
Environmental sounds. Outside noise, partner movement, household sounds — categorized separately so they don't pollute your snore data.
Silence. Discarded immediately. The bulk of a normal night is silence, and saving it would waste storage.

Snore Detection — FAQ

What is the best snore detection app for iPhone?
The strongest iPhone snore detection apps are Snollo, SnoreLab, and Sleep Cycle. Snollo classifies sounds on your iPhone and saves short clips you can play back. SnoreLab processes audio on its servers and benchmarks your snoring against millions of nights. Sleep Cycle puts snore detection behind a subscription. For accuracy plus privacy on the free tier, Snollo is the strongest pick.
How accurate is iPhone snore detection?
Modern iPhone snore detection apps using on-device classifiers reach 90%+ accuracy on distinguishing snoring from other nighttime sounds. The iPhone microphone is more than sensitive enough — placement matters more than the hardware. Place the iPhone face-down on the mattress beside you or within 1–2 meters on a nightstand.
Does a snore detection app actually record me snoring?
Yes — but it varies by app. Snollo saves only short clips of detected snore events (a few seconds each) to your private iCloud container so you can verify them. The bulk of the night is silence and is never recorded. Apps that upload audio to their servers (SnoreLab, Sleep Cycle) record continuously and store data on company infrastructure.
Can a snore detection app diagnose sleep apnea?
No. Only a clinical sleep study can diagnose sleep apnea. What an app like Snollo can do is provide objective data — snore intensity over time, breathing patterns, frequency of events — that helps you and your doctor decide whether a sleep study is warranted. Combine it with a validated questionnaire like STOP-BANG for a stronger signal.
Is there a free snore detection app for iPhone?
Yes. Snollo includes snore detection on its free tier. Snollo uses the Apple ID you already have — no separate Snollo account. SnoreLab has a free tier but reserves most analysis features for the paid version. Sleep Cycle's free tier does not include snore detection.
Will a snore detection app drain my iPhone battery?
A full night of audio classification on iPhone uses 10–15% of battery if you're not plugged in. Most people keep the phone charging on a nightstand overnight, which makes battery drain a non-issue. Running the model on your iPhone is far more efficient than apps that upload audio to cloud servers.
