Whole night or trigger clips, what 2,656 reviews say people found, and a field guide to snoring, talking, grinding, groaning and the gasp worth a doctor’s visit.
An app that records noises while you sleep keeps the microphone open all night and either saves everything or saves a clip each time its classifier recognises a sound. If you don’t know what the noise is yet, pick a whole-night recorder, because a clip app keeps only the sounds it can name. Snore Timeline records the whole night on iPhone and Android, labels snoring, gasps, coughs, sleep talking, laughter and breathing pauses, marks anything it couldn’t name in apricot so you can play it, and charges nothing, with the audio kept on your phone. Apple’s Voice Memos is the zero-cost fallback, with eight hours to scrub by hand.
Eight iPhone recorders on the question that matters when you don’t know what the noise is: does it keep the whole night, and what does it name. Claims come from each app’s listing and help pages, cited below. I built Snore Timeline, so weigh its row with that in mind.
| App | Keeps the whole night | Sounds it names | Playback without paying | Purchases | Privacy label |
|---|---|---|---|---|---|
| Snore Timeline | Yes, continuous, no sampling | Snoring, gasps, coughs, sleep talking, laughter, breathing disruptions, plus Loud Sound for anything else | Yes, every moment of the night | None. No subscription, no in-app purchases | Data Not Collected |
| SnoreLab | Samples by default; full night is Premium [13] | Snoring; other sounds show as gray noise bars [13] | A limited number of recordings per night on the free version [13] | $5.99 to $59.99 | Collects data, incl. Usage Data used to track you |
| Sleep Cycle | No. Clips of detected noises [27] | Snoring, coughing, sleep talking [27] | Snore and sound detection sit under Premium on its help center [14] | $2.99 to $57.99 | Collects data, incl. Identifiers used to track you |
| Pillow | No. “Important audio events” [25] | Snoring, sleep apnea, sleep talking [25] | No. Sound recordings are Premium [15] | $19.99 a month, $49.99 a year | Collects data |
| ShutEye | No. Clips of detected sounds [16] | Snoring, sleep talk [24] | Not stated; 51 of its 150 most recent reviews raise the subscription | $4.99 to $69.99 | Collects data, incl. Identifiers used to track you |
| Sleep Talk Recorder | No. Trigger clips [18] | Talking, snoring, unknown | Partly; “Unlock all nights” is a purchase [18] | $3.99 to $29.99 | Collects data |
| Noxogy (was Prime Sleep Recorder) | No. Sensitivity-triggered clips [20] | Snoring, talking | Reviews from 2025 and 2026 say most clips sit behind the subscription | $5.99 a month, $23.99 once | Collects data |
| Apple Voice Memos | Yes, one file, limited by storage | None | Yes | Free | Collects data (Audio Data linked, for iCloud sync) |
Three more get a line. Dream Talk Recorder, 2,730 ratings at 4.7, records only when it hears talking or snoring, caps the free version at two hours of clips, and must stay open on screen all night [19]. Snore Recorder - Sleep Monitor, 4,297 ratings at 4.5, lists no in-app purchases, also asks you to leave it open, and claims “AI sleep apnea detection”, a medical claim I’d treat with care [23]. SnoreCam saves 30-second video clips on a trigger and costs $9.99 a month after three nights [17].
Every app on this page listens all night. The difference is what it keeps. Small files are why most of them keep clips, and a whole-night recorder draws its labels on top of everything.
| Question | Whole-night recorder | Trigger-clip app |
|---|---|---|
| What gets saved | Every minute. Snore Timeline runs Apple’s Sound Analysis framework on the phone and never stops, so a quiet gap means a quiet room | A few seconds around each sound the classifier can name, snore or speech |
| What gets missed | Nothing in the audio. A label can be wrong, and you play the moment to check | Anything without a label: a groan on the out-breath, a cat on the dresser, whatever your partner swears you do at 3 a.m. |
| Storage | Snore Timeline: 8 to 25 MB an hour, 64 to 200 MB a night, 1 to 8 GB cap. Voice Memos: your free space | Small, until a fan trips the trigger all night. Noxogy reviewers reported eight-hour fan recordings in 2019 and 2026 [20] |
| Which apps | Snore Timeline; Apple Voice Memos; SnoreLab on Premium [13] | Sleep Talk Recorder, Dream Talk Recorder, Noxogy, Pillow, ShutEye and Sleep Cycle describe saving detected sounds; SnoreLab’s free tier keeps samples [13] [17] |
| With the screen locked | Snore Timeline records locked, face down on the nightstand. Voice Memos keeps going until another app plays audio [10] | Only if its developer added the audio background mode [11]. Dream Talk Recorder and Snore Recorder - Sleep Monitor say stay open on screen [19] [23] |
The labels are the start. The unlabelled bars are the point.
I pulled the most recent US App Store reviews for nine recorders: every available page for Sleep Talk Recorder, Dream Talk Recorder, Noxogy, Leap Health’s Sleep Tracker, Sleep Well and Snore Recorder - Sleep Monitor, and the first 150 each for ShutEye, Pillow and SnoreLab. The counts are keyword tallies, so read them as orders of magnitude, and each example paraphrases one review.
| Theme | How many reviews | One example | Source |
|---|---|---|---|
| The subscription wall, the top complaint for every subscription app | Pillow 62 of 150, ShutEye 51 of 150, Noxogy 96 of 500, Leap 56 of 399, Sleep Well 42 of 177 | January 2026: a Sleep Talk Recorder user woke to find 90 percent of the night’s clips of her own voice behind a $35 unlock | [18] [20] [21] [22] [24] [25] |
| Recording first, charging second | Pillow’s own help center puts sound recordings under Premium | July 2024: a Noxogy reviewer suspected the app of adding sounds to the teaser to sell the upgrade | [15] [20] |
| A fan fills the night with clips | False-detection complaints: Sleep Talk Recorder 31 of 500, Noxogy 38 of 500, Dream Talk Recorder 4 of 142 | May 2025: 450 clips of static from a quiet fan across the room, on the lowest sensitivity, plus birds outside (Sleep Talk Recorder) | [18] [19] [20] |
| A whole night of fan | Noxogy in 2019 and 2026 | October 2019: a Noxogy user woke to an eight-hour recording of his fan and asked why the app can’t filter a constant noise | [20] |
| Can’t tell the fan from yourself | Leap false-detection complaints: 7 of 399 | January 2024: a Leap user slept with a fan on, the app recorded all of it, and she couldn’t tell which sounds were hers | [21] |
| The clip was the dog | Pets named in 15 of Noxogy’s 500, 6 of Sleep Talk Recorder’s 500, 1 each of SnoreLab’s and Pillow’s 150 | July 2026: after a month, a SnoreLab user decided every clip was the French bulldog. April 2026: a Pillow user catches only the dog | [25] [26] |
| The clip was the partner | Partners named in 7 of SnoreLab’s 150, 2 of Sleep Well’s 177, 1 of ShutEye’s 150 | January 2025: a Sleep Well reviewer can’t tell her snoring from her husband’s, and the same for coughing | [22] |
| The clip was the CPAP hose | ShutEye, 1 of 150 | July 2026: what the app called snoring and coughing was the CPAP hose rubbing on the table | [24] |
| Clips mislabelled | Sleep Talk Recorder’s three categories: talking, snoring, unknown | September 2026: a user testing with her husband found talking filed as unknown and unknown as talking | [18] |
| Clips cut short | Missed-sound complaints: Sleep Talk Recorder 21 of 500, Noxogy 22 of 500. “Nothing recorded”: 40 and 31 | April 2017: a Noxogy user’s husband talked for a full minute; two seven-second fragments survived | [18] [20] |
| Whole night, but you can’t save the moment | Sleep Talk Recorder, after a version that records all night | March 2026: the app wouldn’t let her save the one minute where she spoke, so she keeps hours of audio to reach one moment | [18] |
| Why: curiosity, or a partner to settle | Curiosity leads at Sleep Talk Recorder, 69 of 500, and Noxogy, 38 of 500; partner stories run 18 and 20 | February 2018: a Noxogy user’s wife insisted she didn’t snore. The recording settled it | [18] [20] |
| Why: health worry | Leads at SnoreLab, 30 of 150, and Pillow, 18 of 150 | September 2026: a Snore Recorder reviewer hears tiny snores followed by a quick gasp and plans to take it to a doctor | [23] [25] [26] |
| Why: the paranormal | About 34 mentions across the whole sample | In several, the voice that isn’t theirs reads like a partner, a TV, or the app’s own paywalled teaser | [18] [20] |
The strongest health example is older. In May 2015 a Sleep Talk Recorder user with a sleep study showing severe apnea replayed the night and heard where her breathing stopped [18]. The dog and the partner aren’t bugs either. A microphone records the room, and a clip without context leaves you guessing who made the sound.
Snore Timeline treats steady noise (fans, air conditioners, rain) as a separate baseline and doesn’t turn it into events. A loud fan still masks quiet breathing, and once a room sits above about 45 dB more sounds land under Loud Sound instead of snoring. The detection page explains the trade.
Before you pick an app, know what you’re listening for. The figures and doctor-visit triggers come from the sleep-medicine bodies cited in each row.
| Sound | How common | What it sounds like | See a doctor when | Source |
|---|---|---|---|---|
| Snoring | About half of people at some point; habitual in 40 percent of adult men and 24 percent of adult women | Low and rumbly, on the in-breath, riding the rhythm of breathing | It comes paired with choking or gasping, or you’re tired by day despite enough sleep | [1] |
| Sleep talking | 60 to 65 percent lifetime; half of young children; about 5 percent of adults | Half of recorded sleep speech is mumbling, half resembles ordinary conversation. The sleep talking guide compares 17 apps and covers transcription | It gets more frequent, starts at an older age, or comes with limb movements or daytime sleepiness | [2] [29] |
| Teeth grinding | About 8 percent of young to middle-aged adults have sleep bruxism | A short, dry, rhythmic scrape in clusters, most common in light sleep. No microphone hears clenching; see the teeth grinding guide | You may not know unless a bed partner hears it. Regular grinding damages teeth, so see a dentist if it’s severe | [3] |
| Groaning (catathrenia) | Unknown. A 2024 review of 31 studies couldn’t put a figure on it | A long, steady, musical moan on the out-breath, rhythmic where snoring is chaotic | If that’s what you hear, catathrenia is the word to bring to a doctor | [4] |
| Laughing, crying, shouting | 98 percent of 495 young adults acted out a dream in the past year; 72 percent smiled or laughed | A chuckle is ordinary. Shouting, swearing, punching and kicking are the signs of REM sleep behaviour disorder | Shouting and violent movement, most often in men over 50. RBD affects under 1 percent; the AASM says see a sleep doctor | [5] [6] |
| Coughing | Most coughs clear within three to four weeks | The usual causes: colds, smoking, reflux, allergies, post-nasal drip | A cough lasting more than three weeks. The NHS says see a GP, the UK term for a family doctor | [7] |
| Silence, then a gasp | The pattern the AASM lists for sleep apnea | Snoring, then silent breathing pauses, then choking or gasping sounds | If someone says you gasp for air in your sleep, talk to a healthcare provider. A recording shows the pattern and diagnoses nothing | [8] [9] |
On Snore Timeline’s timeline, snoring is the rose colour, its energy in the 50 to 250 Hz band the darker orange shading marks, and coughs count on their own in green, so a bad week shows as a number. A breathing disruption, in pale purple, means a stretch of audible breathing, then ten seconds or more of silence, then a recovery sound. It’s an audio pattern to show a doctor, never a diagnosis, since quiet events make no sound; the breathing disruptions page spells out the limits.
The pages that rank for this query skip this part. This is what I do on my own nights.
Two nights beat one. A sound that recurs at the same point in the night, or only on nights you can tag (wine, a late meal, a cold), tells you more than a single clip, and Snore Timeline’s sleep factors compare tagged nights with untagged ones once you have two of each; the remedy guide walks through it.
At a glance covered what each app keeps and charges; this table covers the rest.
| App | How it records | Its strengths | Its limits | Source |
|---|---|---|---|---|
| Snore Timeline | Whole night, with a Loud Sound switch for everything else and an Automatic threshold that re-measures the room every minute | Three quality tiers, a 1 to 8 GB cap, Episode-Only mode that trims silence, sleep stages and a score from breathing with no wearable | The breathing flag hears only audible events, and the stages are estimates. No account, server or analytics; label Data Not Collected; nothing to buy | Storage page |
| SnoreLab | Samples by default; full-night recording on Premium | The best-known snore recorder, 57,000 ratings at 4.7. Snore Score and remedy tracking, which Snore Timeline answers with a sleep score and 23 factors | Non-snoring sounds show as gray noise bars without labels; sleep talking isn’t listed; export is Premium. Good if snoring is the only question | [13] [26] |
| Sleep Cycle | Clips of detected noises | A smart alarm first. Its feature page promises to tell your snore from your partner’s and to name pet, household and neighbour noise | Its help center lists snore detection and sound detection under Premium, and the whole night is not on offer | [14] [27] [31] |
| Pillow | “Important audio events”, processed on the device | Apple Watch depth and an Editors’ Choice badge, with a recorder attached that labels snoring, sleep apnea and sleep talking | Sound recordings and CSV export sit in Premium. I’d read its “sleep apnea” label as a sound class and nothing more | [15] [25] |
| ShutEye | Clips of detected sounds; its blog says the AI analyses files recorded by the microphone | 350,000 ratings and a sound library of more than 70 sounds. Selected recordings such as snoring can be played back and shared | Its FAQ covers billing and says personal information sits on encrypted servers. Clip retention isn’t stated anywhere I found | [16] [24] |
| Sleep Talk Recorder | Trigger clips by design; a filter fires on speech | The oldest dedicated app, from 2010. It sorts clips onto a timeline night by night and keeps a public top list of shared clips | 170 of its 500 most recent reviews are one star, and the fan and the unlock account for most of them | [18] |
| Noxogy, formerly Prime Sleep Recorder | Sensitivity-triggered clips; same app, new name | 13,000 ratings at 4.5. A snoring-only mode, a noise graph for the night, CSV export of history, iCloud sync | A decade of reviews describe clip caps and whole-fan nights; the trigger has changed with versions. Pick the $23.99 one-time price | [20] |
| Apple Voice Memos | One file, every sound; already on the phone, so tap record and put it down | Skip Silence jumps the gaps, Wide Spectrum keeps room sound in, and iCloud syncs to every device, hence its Audio Data label | It stops recording if another app plays audio. No labels, no list, no numbers | [10] [28] |
Mine exports the full night as one file, every episode as clips, or CSV files, all from the Files app. The export page has the paths.
Snore Timeline analyzes audio on your phone. It is not a medical device and does not diagnose sleep apnea, bruxism, REM sleep behaviour disorder or any other condition. Its sleep stages are estimates. If a recording holds gasping, choking, long silences between breaths, shouting or violent movement, take it to a doctor.
If you don’t know the noise yet, the best app keeps the whole night, because trigger-clip apps save only the sounds their classifier recognises. Snore Timeline records the whole night, labels six kinds of sound plus breathing pauses, marks unnamed sounds so you can play them, and charges nothing: no subscription, no in-app purchases. Voice Memos keeps the whole night with no labels, and SnoreLab keeps samples unless you pay for full-night recording.
Yes. Voice Memos comes with the iPhone and records one long file, and Snore Timeline is free with no in-app purchases and adds labels, a timeline and export. Most other recorders install free and then charge to play back what they recorded: Pillow’s help center lists sound recordings under Premium, Sleep Talk Recorder sells an “Unlock all nights” purchase, and SnoreLab limits free playback per night.
Plug the phone in, put it on the nightstand one to four feet from your head, and open the recorder before you lie down. Snore Timeline keeps recording with the phone locked and face down, while Voice Memos stops the moment another app plays audio. In the morning, open the episode list or scrub the file and play the loudest or strangest moments first.
It depends on the app: reviews of Sleep Talk Recorder, Noxogy, Leap’s Sleep Tracker and Dream Talk Recorder describe hundreds of fan clips or a whole night of fan. Snore Timeline tracks steady noise as a baseline and doesn’t turn it into events, though a loud fan still masks quiet breathing, and above about 45 dB more sounds get filed as Loud Sound instead of snoring. Switch the fan off for a night if you can.
Check the rhythm first: a sound once per breath, in a train, is snoring on the in-breath or groaning on the out-breath, and a single sound with no rhythm tends to be the room, a pet, a partner, the house. Half of recorded sleep speech is mumbling, so a muffled voice can be you, and a chuckle is common, since 72 percent of young adults in one study had laughed in a dream. Silence followed by a gasp is the one to take to a doctor.
Read the privacy label, which is the developer’s own declaration, checked 9 October 2026. Snore Timeline declares Data Not Collected and has no server; Voice Memos declares Audio Data linked to you because of iCloud sync; SnoreLab, ShutEye, Leap’s Sleep Tracker and Snore Recorder - Sleep Monitor declare Audio Data on their labels. SnoreLab’s FAQ describes an encrypted Premium backup on its server, and ShutEye’s FAQ says personal information sits on encrypted servers.
Free. No subscription, no account, no in-app purchases.
