Ask first. Then placement for two sleepers, telling two snorers apart by ear, the CPAP noises that trip a recorder, and how to share the clip without a fight.
Ask first, then put a phone on the snorer’s side of the bed, one to two feet from their head, plugged in and face down, and let a snore app record the whole night. In the morning play the loudest episodes and decide by ear: a snore next to the phone sounds loud and full, one from across the bed sounds faint. Snore Timeline does this on iPhone and Android with nothing to buy and saves any episode as a clip to share; on CPAP nights, lower the sensitivity and hide the brief episodes, because mask hiss and hose rub show up as false snores. A silent pause followed by a gasp or a choke is a reason to see a doctor.
Five snoring apps, compared on what matters when the person recording isn’t the one snoring: whether the maker says anything about a partner, whether anything tells two sleepers apart, and whether you can hand over a clip. Claims come from each listing, FAQ or help center, cited below. I built Snore Timeline, so read its row with that in mind.
| App | Guidance for recording a partner | Tells two sleepers apart | Share a clip | Purchases | Privacy label |
|---|---|---|---|---|---|
| Snore Timeline | Yes, a support guide on placement, attribution and sharing | No. You decide by ear, with a sensitivity setting, a minimum-duration filter and per-episode removal | Yes. Any episode as a clip with two seconds of context, by Messages, email or AirDrop; full night too | None. No subscription, no in-app purchases | Data Not Collected |
| SnoreLab | FAQ: cannot separate two snorers; try separate rooms for a night or two [17] | No [17] | Email of snore sound files [24] | $5.99 to $59.99 | Collects data, incl. Usage Data used to track you |
| Sleep Cycle | Help center: harder if the other person is louder; partner link for two Premium iPhones on one Wi-Fi, iOS only [16] | Who’s Snoring, Premium: you label clips as me or not me over several nights [15] | Not stated | $2.99 to $57.99 | Collects data, incl. Identifiers used to track you |
| SnoreClock | Listing: check if you snore, if your partner snores [26] | No | Not stated | $9.99 once | Data Not Collected |
| Koala Nap | Built for the snorer, to help the partner sleep, with wrist alerts; says it supports CPAP users [27] | No. Four reviews say it buzzes for the partner’s snoring | Not stated | $4.99 a month to $39.99 a year, 7-day trial | Collects data (Audio Data, not linked) |
Pillow, ShutEye and Snore Recorder - Sleep Monitor have nothing in their listings or help pages about a partner. Snore Control’s listing asks whether you are sick of your partner’s snoring and offers sharing by email and iMessage [28].
Every page that ranks for this query speaks to a snorer recording themself. Sleep Cycle’s blog, the one aimed at a partner, says record them to prove them wrong, and nothing about telling them [18]. One page in the set mentions consent [19]. I’d put it first.
The better reason to ask is that the recording is for the snorer. About 40 percent of adult men and 24 percent of adult women are habitual snorers, and most have never heard it [5]. The SnoreLab reviewers who listened to their first night and understood why their wife wanted them in another room went on to do something about it. Nobody got there because someone ambushed them with a clip. “I want to record tonight so we can both hear it” is the sentence.
Your own sleep is a fair thing to bring up. Three studies put numbers on it, and they don’t all agree.
| Study | Couples | What was measured | Finding | Source |
|---|---|---|---|---|
| Mayo Clinic, 1999 | 10 couples, the men with sleep apnea | Spouses in a sleep lab on a night the snorer slept untreated and a night he used CPAP | Arousals fell from 21 to 12 an hour; sleep efficiency rose from 74 to 87 percent, about 62 extra minutes a night | [1] [2] |
| Sleep Heart Health Study, 2008 | 110 couples from a community sample | In-home sleep studies of both partners | Partners of people with disordered breathing slept no worse than other couples, so the toll varies | [3] |
| Blumen, 2009 | 23 women who complained of a snoring partner | Sleep studies with the partner and alone | Six of the 23 snored for more than a tenth of the night themselves, worth remembering before anyone keeps score | [4] |
The app records whatever the microphone hears, and it can’t tell whose body a snore came from. Both of you end up on the same recording. Placement does the first half of the sorting.
I sorted every partner mention in the 1,733 most recent US App Store reviews of eight snoring apps. The five apps with the most mentions are below.
| App | Reviews sampled | Picks up the partner | Proved the partner right | Partner sleeps better after alerts | Example, with date |
|---|---|---|---|---|---|
| SnoreLab [24] | 500 | 11 | 14 | 5 | A woman’s Snore Score blended in her husband’s, caught after a night her remedies should have lowered it (August 2023) |
| Koala Nap [27] | 135 | 4 | 3 | 33 | Buzzed awake for her husband’s snoring; it “doesn’t distinguish a close snore from a loud snore” (June 2024) |
| Sleep Cycle [25] | 250 | 2 | 1 | 0 | With partner link set up, it “frequently confuses the stats between us” (September 2026) |
| Snore Control [28] | 32 | 0 | 1 | 0; four say the phone alert wakes the partner | Vibrating the iPhone just wakes his wife, which is what he was trying to avoid (April 2018) |
| Snore Recorder - Sleep Monitor [29] | 500 | 3 | 1 | 0 | It caught one of his partner’s snores, “but the recording allowed me to identify who it was” (June 2026) |
A third of one SnoreLab reviewer’s clips were his wife (July 2023). Another sleeps in a separate room to record, since that’s the only way he gets a single-person score (December 2023), and SnoreLab’s FAQ gives the same advice, separate rooms for a night or two [17]. Sleep Cycle’s partner link needs two Premium subscriptions on two iPhones on one Wi-Fi [16].
The second half is your ears. The app does the detection, you do the attribution, and it takes a few minutes in the morning.
Count on the app to find the moments and on yourself to name them. If you both snore, record two nights with the phone on each side in turn, and you have two honest timelines.
This is the complaint the ranking pages skip and the reviews don’t. Three SnoreLab reviewers ask it to stop logging the CPAP as snoring, a ShutEye user traced his snores and coughs to the air tube rubbing on a table, and Snore Timeline’s own three-star review from February 2026 came from a partner whose husband tosses and turns with a CPAP hose: 27 signals the first night, four or five real, no way at the time to delete the rest [24] [30]. An update days later added per-episode removal.
The machine isn’t the problem. ResMed’s AirSense 11 user guide puts it at 27 dBA with its humidifier tub and 25 dBA with the side cover [12], under the 45 dB room floor where Snore Timeline’s classifier starts filing sounds as Loud Sound, and the app tracks a steady hum as background noise. What trips a recorder sits at the snorer’s head and comes and goes.
| Noise | Where it comes from | Fix | Source |
|---|---|---|---|
| Hiss from a high unintentional leak | The mask seal, often a mouth leak | Check the leak data; ResMed suggests a different mask type for a mouth leak | [13] |
| Extra noise from the humidifier | A tub not seated in position | Reseat the tub | [13] |
| Noise from the accessories | A clogged filter or a non-ResMed tube | Clear or replace the filter; use the maker’s tube | [13] |
| Gurgling in the tube (rainout) | Condensation building up in the tubing as the snorer breathes | Turn the humidity down a little, use a heated tube, keep the room warmer or wrap the tube | [14] [22] |
| Air rushing through the hose | The hose resting on the nightstand, or rubbing as the snorer turns | A fleece hose cover, or a hose hanger that keeps it off the nightstand | [21] [22] |
| Blowing or hissing toward the partner | The mask’s exhaust vent | A diffuser mask | [21] [22] |
Nobody in those threads records the noise to find it. They wear the mask awake in the evening and listen. An episode list does the same job while you both sleep, and the timestamps tell you whether it’s the 1 a.m. roll-over or the 4 a.m. gurgle.
Four Snore Timeline settings handle a CPAP night.
Two more things on CPAP nights. The breathing disruption flag gets less reliable with a soft machine running, as the breathing disruptions page says, so don’t read a quiet night as a clean one. Tag the night CPAP in sleep factors, and after two tagged and two untagged nights the app tells you whether the therapy is quieting the snoring.
Snore Timeline analyzes audio on your phone. It is not a medical device and does not diagnose sleep apnea or any other condition. A breathing disruption on the timeline is a sound pattern to show a doctor, and quiet events make no sound at all. If the person you recorded gasps, chokes or stops breathing between snores, or is tired through the day, take the recording to a healthcare provider.
Tell them, then put a phone on their side of the bed, one to two feet from their head, plugged in and face down, and start a snore app before you sleep. In the morning open the episode list, play the loudest episodes, and confirm by ear that the loud, full snores are theirs. Snore Timeline records the whole night with nothing to buy and saves any episode as a clip to share.
I’m not a lawyer and this isn’t legal advice. US recording laws cover conversations, with federal law needing one party’s consent and about eleven states needing everyone’s, while UK and EU data protection law leaves purely personal and household activity alone. A recording of a sleeping partner is a grey area with no ruling I could find, so ask first and keep the recording private, since posting it changes the question.
Not by sound alone. SnoreLab’s FAQ says it cannot distinguish one person’s snoring from another’s, and Sleep Cycle’s Who’s Snoring is a Premium feature that learns after you label clips as you or not you over several nights. Placement does most of the work, since the phone favours whoever is nearest, and playback settles the rest: a snore beside the phone sounds loud and full, one from across the bed sounds faint.
The machine is quiet, about 25 to 27 dBA for a ResMed AirSense 11, and the app tracks a steady hum as background. What triggers a snore label is intermittent noise at the mask, such as a leak hissing, the hose rubbing as they turn, air through the vent or condensation gurgling in the tube, and the fixes are a hose cover, a hose hanger, a diffuser mask or lower humidity. In Snore Timeline, set Minimal sensitivity, hide episodes under a few seconds with the Minimum Duration filter, and remove the rest from their cards.
Play it for them, then book a doctor. The American Academy of Sleep Medicine says snoring followed by silent pauses and choking or gasping sounds is likely a sign of sleep apnea, and the bed partner tends to be the one who hears it. Export the clip or the full night from the app and bring it to the appointment; the app flags these from sound alone and never diagnoses anything.
