The best snore recorder records your whole night, not samples of it.
Catch every snore, every word you say in your sleep, and every breathing pause, then play any moment back or read your sleep talking as text. Wake to a smart alarm during light sleep, and see your stages, sleep score, and recovery score in the morning. For every wake-up, you can see what your snoring was doing around it.
I looked at several sleep/snore trackers online and Snore Timeline takes the cake against all the others. The interface is clean and easy to navigate. There are numerous settings available to customize your sleep tracking and events. It can be set to not only log events but ping your watch, phone, or both when an event triggers. You can delay when to start recording and there’s also options for Bluetooth (if you have earbuds in at night) or your phone. This app is amazing and highly recommendable. The only thing that could make this app better would be the ability to change from Celsius to Fahrenheit on the wrist temp. But that doesn’t lower my rating on the app; I still find it totally amazing! And it’s free.

Can’t believe this is real
This app is amazing and the fact that it’s free and I found it off of Reddit makes it even better. The way this app just lets you jump in with no account or anything is soooooo nice. I also really like how the app tracks information while you sleep even with your Apple Watch.

Operationally Amazing
TLDR - clean, minimal, QoL feature heavy, no bs! Great app!
I never take times to write reviews but in a world of poorly developed apps with useless features, this app is a breath of fresh air.
I was told I snored and wanted to try tracking it. I headed to App Store to search for what I expected to be a bloated piece of app slop with a $100/year price tag and maybe a few night free trial so I could use a single helpful feature nested in some side menu of other features I would never use.
What I did not expect was to find this app. This app defies all my expectations and serves the exact purpose I wanted it to. I enjoy how minimal and straight to the point it is. It is intuitive and each time I think of some setting I hope I want to find (e.g. cutting recordings to only events) I scroll and boom, there it is.
Sometimes less is more and in the case of apps, this is everything I wanted in diagnosing and tracking my snoring while tagging factors, easy playback, recording quality settings , and many other QoL features.
I haven’t seen/experienced any obvious bugs beyond a little Ui components like buttons with with backgrounds that don’t match the view behind it.
Nonetheless, shoutout to the dev(s) on this app. Truly a good experience using this app.

Best sleep app and developer
This is the exactly the sleep app I wanted and has features that none of the popular ones could provide without some sort of payment. I want to highlight how much the developer cares about its users. I emailed them about an audio issue I had with AirPods and they were able to develop a fix within hours. This is a must try app if you are curious about your sleep quality and snoring.

I’m amazed. How is this free!
At first it seemed too good to be free. I was hesitant to install it. I’m blown away by the quality and amount of visualization. The watch integration is incredible.

Three thumbs up!
What an impressive app!
Incredibly robust, long feature list with lots of anticipated needs and corresponding features. Super impressed with what's there! Kudos to the developer for the level of maturity obtained. If I had a third hand - it'd be rated three thumbs up!

Great App!
I hardly ever write reviews, but I want other people like myself (skeptics by nature) to know that this is an excellent app that preforms exactly as advertised, and most importantly, without ANY additional fees, subscriptions, ads, paywalls, etc.
I learned about this app on Reddit, from the developer himself, I believe. I decided to give it a try, and was pleasantly surprised to find out if it does exactly what it said it would do. A rare find these days! Highly recommend if you’re looking for a solid, straightforward snore app.

Better than other paid apps!
I am surprised this app is free because it works better than other premium snore recording apps that cost money. Much easier to navigate and listen to recordings compared to other apps. Kudos to the developer!

Phenomenal
Props to the developers for creating a high quality sleep sounds tracker that’s not behind a ridiculous paywall. I wanted to track my teeth grinding issues and the app detects my bruxism episodes accurately. THIS should be the app recommended in Apple Health, not Sleep Cycle or BetterSleep.

More Than Snores
A number by itself doesn't tell you much. Snore Timeline compares each overnight vital to your own baseline and says in plain language what it means, so you know whether a reading is worth paying attention to.
0br/min
Steady
Breathing Rate
Calm and even. A steady rate through the night usually means relaxed, undisturbed sleep. Spikes can point to stress or a disruption.
0bpm
Good
Heart Rate
Settled low. Your heart drops to its resting floor while you sleep. The further below your average it gets, the more your body recovered.
0ms

HRV
Above your average. More variation between beats means your nervous system got to recharge overnight instead of running under strain.

Blood Oxygen
Well supplied. Holding at or above 95 percent means your breathing kept your blood well oxygenated all night.

Audio-Based Estimation
How We Estimate Your Sleep Stages
Using nothing but your phone's microphone, Snore Timeline estimates when you're in light sleep, deep sleep, or REM, based on published research into how breathing changes across sleep stages. When your breathing is too quiet to hear, it doesn't guess. Those calm stretches get labeled Silence and counted as restful sleep.
Listen to Your Breathing
Your phone's microphone picks up your breathing rate, how regular it is, and your snoring patterns, all night long
Establish Your Baseline
After about 15 minutes the algorithm has learned your personal breathing rate and regularity, and sets its thresholds around your own patterns
Analyze Breath Regularity
Thresholds from published research look at regularity and variance. Steady, even breathing points to deep sleep. Irregular breathing with a lot of variance points to REM
Adapt Through the Night
The model knows how a night is shaped. Deep sleep peaks early on, and REM builds toward morning
Quiet Sleepers
Since everything comes from audio, very soft breathing, or a fan covering it up, can be inaudible. Instead of guessing a stage, the app labels those undisturbed stretches Silence and credits them as restful sleep

How We Detect Disruptions
On top of snore detection, the app picks out moments when you stop breathing for 10 seconds or more, so you can spot patterns worth bringing to a doctor.
Baseline Observation
Listens to your breathing for at least a minute first, so it knows what your normal sounds like
Silence Detection
Watches for a stretch of quiet lasting 10 seconds or more, the main sign of a breathing disruption

Timeline Marking
Marks each one on your timeline at the exact time it happened, so you can tap and listen

A Nudge When You Snore and a Smarter Alarm
Most snore trackers only tell you about it in the morning. Snore Timeline nudges you when you snore, with a sound from your iPhone or a tap from your Apple Watch, and wakes you when you're sleeping lightly.
Snore Nudge
A sound or a tap when you snore
When the app hears you snoring, your iPhone plays a short tone, or your Apple Watch taps your wrist, just enough to get you to shift position without waking you. The recording keeps going, and it works with your iPhone locked.
Keeps nudging for as long as the snoring does, a step louder each time one doesn't help, and stays quiet before your alarm
Scores every nudge in the morning, from "Stopped snoring for 2 min" to "Snored through"
Marks every nudge on the night's snoring chart and lets you page through them one at a time, so you find out whether changing position works for you
Give the alarm a window of 15, 30, or 45 minutes and it rings when it finds you sleeping lightly, instead of pulling you out of deep sleep at the exact minute.
Or wake with no sound at all: turn the alarm off and your Apple Watch taps your wrist instead, so your partner sleeps through it
Rings at your set time no matter what, so you won't oversleep
Fades in gently, and tells you in the morning how many minutes early it woke you
What makes Snore Timeline different from other snore tracking apps?
Snore Timeline keeps the full night's audio and lays it on an interactive timeline you can scrub through and tap to hear. It records continuously instead of sampling, so a quiet hour shows up as a quiet hour. Coughs, gasps, sleep talking, and breathing pauses each get their own category, and sounds that happen close together are grouped into episodes you can play back.
Sleep stage data comes in from Apple Watch, Oura Ring, Whoop, Garmin, and Ultrahuman. Detection runs on your phone. No cloud, no account, no subscription.
What is the difference between the sleep score and the recovery score?
The sleep score rates how you slept, based on your recording. Duration, efficiency, sleep stages, snoring, and bedtime regularity, on a 0 to 100 scale. The recovery score is about how your body responded overnight, based on your Apple Watch vitals. Heart rate variability, resting heart rate, breathing rate, blood oxygen, wrist temperature, and time asleep, each compared to your own baseline.
The morning summary blends the two into one plain-language status, like "Well Recovered." The recovery score needs a wearable that writes to Apple Health. The sleep score works from audio alone. Both are for your own insight, and neither is a medical assessment.
Can it wake me without an alarm sound, so my partner keeps sleeping?
Yes, with an Apple Watch. Turn the alarm sound off and the wrist nudge on, and the alarm reaches you as a steady rhythm of taps on your wrist. Two waves of taps over about six minutes, so a deep sleeper gets a second chance. Your partner sleeps through it.
It works with the Smart Wake Up Alarm, so the taps can come during light sleep instead of at a fixed minute, and dismissing the notification on your watch stops the alarm and the recording together. You can also run the taps alongside the sound if you want both.
No. Snore Timeline is free, with no subscription. Everything is included: breathing disruption detection, episode grouping, nightly summaries, and data export. There are no in-app purchases.
Is my data private?
Yes. All audio processing happens on your iPhone. There are no cloud uploads, no external servers, and no account. Your recordings stay on your device and nobody else can get at them. If you want to share data with a doctor, you export it yourself.
Yes. Open a Sleep Talking episode and tap Transcribe, and the words appear under each clip. A speech model on your iPhone does the transcribing, so your recordings never leave the phone, and it works in airplane mode once the model is downloaded.
The first time, the app asks before a one-time download of the model, 574 MB on most recent iPhones. Clips with no clear words come back marked as unrecognizable instead of filled with invented sentences. Transcription is free like the rest of the app.
Yes. Snore Timeline listens for breathing pauses in your sleep audio. It looks for silent stretches of 10 seconds or more followed by a gasp or some other recovery sound, and marks those breathing disruptions on your timeline so you can see the pattern. This is audio analysis only. The app isn't a medical device, and if you're seeing pauses it's worth bringing them to a healthcare professional.
Snore Timeline uses Apple's sound classification to analyze your audio continuously through the night, in real time. There's no calibration or setup, and detection starts the moment you press record. The app identifies snoring, gasps, coughs, breathing, and sleep talking by looking at both the shape of each sound and its frequency makeup. All of the processing happens on your device.
Yes. Snore Timeline works with Bluetooth audio devices including AirPods, so you can record through the night without running the phone's battery down.
You also pick which mic records. Choose iPhone Microphone in Settings and the phone records while your AirPods keep playing music at full quality, or Automatic to record through your headphones' mic whenever they're connected.
Tap the download icon to open the Export Report sheet, pick a date range, and choose what to include: summaries, sleep stages, events, biometrics, and audio. For audio, turn on Include audio and pick Full-night recording for one file of the whole night or Per-episode clips for every episode. The report comes out as CSV files plus whatever audio you chose to bundle.
Exported files are saved to your device, organized into two folders:
Yes. In Settings, turn on Storage Limit and pick a cap between 1 GB and 8 GB. Once your recordings pass it, the app clears the oldest nights first. With Keep History switched on, only the playback goes. Your episodes, sleep analysis, and timeline stay, so weekly trends keep working for nights you can no longer hear.
To reclaim space right away, set a low cap and tap Over Limit - Tap to Clean Up in Settings. Episode-Only Storage takes a different route: after each night it drops the quiet stretches and keeps the segments with detected episodes, so files shrink while every episode stays playable. Deleting a single night from Settings removes that date's audio and data together.
