The free snoring app for iPhone and Android that records your night
SleepTrace records your snoring and shows where in your night it happened.
Yes, there is a free snoring app: SleepTrace records your snoring every night on iPhone and Android, saves each episode as a short clip with a decibel reading, and estimates which sleep stage it fell in. The free plan includes 3 playable clips a month, Premium unlocks unlimited clips. No wearable is needed: the phone stays by the bed, the app stays open and plugged in, and the sound analysis runs on the device.

How to
Record your snoring tonight
- Put the phone within a couple of metres of your headOn the nightstand or the bed frame, plugged into a charger. No special position, nothing under the mattress.
- Press start before you go to sleepOne tap. The app has to stay open (the screen dims by itself), with the phone on its charger.
- Sleep normallyThe sound analysis runs on the phone.
- Listen back in the morningYou get a timeline of the night with every snoring episode marked, each with a decibel reading and a short clip you can play. On the free plan, 3 clips a month are playable.
The difference
A recorder tells you that. This shows you when.
Snoring on its own is a sound. Snoring placed inside the night is easier to act on, because you can see whether it clusters in one stretch or runs through everything. The stage placement is an estimate made from audio, not a lab measurement.
Is there a free snoring app, and which is the best free one?
There are several, and none wins on every point. A good one has to do three things: record all night without a subscription, let you hear what it caught, and say plainly what sits behind a paywall. By that yardstick, SleepTrace, SnoreLab and Sleep Cycle each cover a different part. SnoreLab is a dedicated snoring log with a Snore Score and a remedy test. Sleep Cycle bundles snore detection into a broader sleep tracker, but its App Store text lists snore detection under Premium. SleepTrace records and labels snoring on the free plan, with 3 playable clips a month.
Wanting a free snoring app with no subscription is reasonable, so read the listings closely. SnoreLab's App Store page lists a one-time purchase next to its subscriptions; the pages we opened for the other apps in the table do not list one. SleepTrace's free plan stays available, but it caps playable clips at 3 a month; unlimited clips need Premium.
Best free snoring app for iPhone: what to compare
Whichever iPhone snoring app you try, compare on four points: does the free tier let you hear your own snoring, does it record the whole night or only start when it hears something, what does it tell you besides loudness, and does it need a watch. SnoreLab leans on a Snore Score and remedy testing. Pillow puts sound recordings behind Premium and works best with an Apple Watch. SleepTrace is built for the phone alone and adds estimated sleep stages next to the clips. Which one you end up keeping depends on whether you want to reduce snoring or understand what it does to the night. The quickest way to choose is to try two of them for a week and keep the one whose morning view makes sense.
Whichever you pick has to last the whole night: keep the phone plugged in and the app open, because a recording that ends early gives a misleading picture of your snoring.
Snoring app for Android: free to record
SleepTrace is on Google Play too, and a free snoring app for Android works the same way as on iPhone: phone next to the bed, start the recording, and in the morning see the marked snore episodes on a timeline. The night is analysed on the device. The free plan includes 3 playable clips a month. If you only want something to try on Android without paying, SleepTrace and Sleep as Android are the two in the table built for the platform; Sleep as Android's vendor page does not state a price.
Pairing with an Apple Watch exists only on the iPhone. For snoring itself it does not matter.

Measure, track, reduce: what a snoring app can and cannot do
To measure snoring, an app uses the microphone and sorts sounds into snoring and everything else. What you get from that is counts and loudness, not a cure. To follow the numbers over weeks, look for a history view: that is where you see whether a change in your evening or your pillow made a difference, so check that the history is still there after the first few nights.
Anti-snoring apps make a different claim. The listings in the table describe two kinds. Some, like SnoreLab, let you test a remedy and see the effect in the next morning's score (its listing calls this "Remedy Testing"). Others, like Koala Nap, try to interrupt you with a gentle alert when snoring starts. SleepTrace records and shows; it does not claim to reduce snoring. If you want alerts on a watch, see snoring apps for Apple Watch and Garmin.
Accuracy is a fair question. Two recent studies looked at smartphone snore detection. A bench study of the SleepWatch app (PMID 40153546) used 36 simulated snoring files from 18 participants and reported an average sensitivity of 86.3% and accuracy of 95.2%. Another study (PMID 40190583) recorded smartphone audio from 214 participants alongside polysomnography; its deep-learning model was tested on 55 of those 214 participants and reported 89.8% sensitivity and 91.3% specificity for snoring. Neither tested SleepTrace, so they show that snore detection from phone audio can work, not how well any one app does it.
What Reddit recommends, and how to read it
Reddit threads about snoring apps are full of opinions. We have not used any of them as a source here, so we cannot tell you what Reddit recommends. A thread can still be a lead if you read it with snoring in mind: does the writer sleep alone or next to someone who snores too, how far was the phone from their head, and is the comment recent enough that its free tier still exists? The recommendation that holds up is the one you can confirm yourself in one night.
Limits
What this app cannot do
It cannot diagnose sleep apnea. No app can. SleepTrace shows snoring patterns and apparent pauses in breathing, plus a screening indicator (a risk level and an average index). A diagnosis needs a sleep study arranged by a doctor. It is a wellness app, not a medical device.
It cannot separate two sleepers with certainty. The microphone records the room. Placing the phone on your side helps, but if your partner snores too, the clips are how you find out who is who.
It does not hear everything. It does not recognise mouth breathing, reflux, teeth grinding, sleeping position, movement or temperature. Clips are saved only for snoring, talking and coughing.
It cannot measure your heart. Heart rate and HRV need a sensor on your body. Pair an Apple Watch if you want those; it is optional, not required.
Common questions
Snoring apps, answered
Yes. SleepTrace is available on Google Play and records your snoring on Android for free. The analysis runs on the device, and the free plan includes 3 playable clips a month. Only the Apple Watch pairing is iPhone-only.
Yes. SleepTrace records your snoring every night on the free plan, labels each episode and estimates your sleep stages. The free plan includes 3 playable clips a month; Premium unlocks unlimited clips and long-term trends.
It depends on what you want. SnoreLab is a dedicated snoring log with a Snore Score and remedy testing. Sleep Cycle bundles snore detection into a wider sleep tracker, with snore detection under Premium according to its App Store text. SleepTrace records the snoring and places each episode on a timeline of estimated sleep stages, without a wearable. If you only want to know whether you snore, any of them will show it.
SleepTrace's free plan has no end date, but it limits playable clips to 3 a month. SnoreLab's App Store listing includes a one-time purchase alongside its subscriptions. Check the current listing before buying, because prices and plans change.
Detecting snoring from audio is one of the easier tasks in sleep tracking: snoring is loud and rhythmic. Two 2025 studies (PMID 40153546 and PMID 40190583) reported sensitivities of 86.3% (simulated snoring files) and 89.8% (a test set of 55 of 214 participants) for smartphone snore detection, though neither tested SleepTrace. Estimating sleep stages from the same audio is harder, and every consumer tracker produces an estimate rather than a clinical measurement.
Apple's own sleep pages describe sleep stages, a Sleep Score, heart rate and respiratory rate, and do not mention snoring recordings. Its sleep apnea notification, according to Apple, uses the accelerometer to look for breathing disturbances. To hear and replay your snoring you need an app that uses a microphone, usually on the iPhone. More in our page on snoring apps for Apple Watch and Garmin.
It records the room, so a second sleeper is picked up too. Placing the phone on your side of the bed and close to your head biases the recording towards you, but SleepTrace cannot tell two people apart with certainty. The clips let you check for yourself.
No app can diagnose sleep apnea, that needs a sleep study arranged by a doctor. SleepTrace can flag snoring patterns and apparent pauses in breathing, give a screening indicator and hand you the recordings, so you can bring something concrete to an appointment. It is a wellness app, not a medical device.
Treat it as a lead, not a verdict. Check the date of the comment, because free tiers and prices change, look for whether the person has a connection to the app, and confirm the claim in the store listing. One night of recording with the app tells you more than any thread.
SleepTrace is a wellness app and does not diagnose, treat or prevent any medical condition. If you are worried about your breathing during sleep, speak to a qualified healthcare professional.
