Snore Timeline vs ShutEye: Snore Tracking, Sounds, and Privacy

At a glance

Price

Snore Timeline is free. It has no subscription, no in-app purchases and no premium tier, so every feature on this page ships to every user.

ShutEye is free to download, and its FAQ says some basic features work without a subscription. Advanced sleep tracking and personalized insights need a premium plan. The App Store listing showed these in-app purchases:

• 1-Month ShutEye Premium: $9.99
• Limited Time Offer (6-Month): $19.99
• ShutEye Gold, Special Offer and Limited Time Offer: $29.99 each
• 1-Year ShutEye Premium: $59.99
• 1-Year ShutEye Family Plan: $59.99

The listing's description names the main plan as an auto-renewing subscription at $59.99 a year. ShutEye's FAQ adds a 7-day free trial for first-time subscribers and a Family Plan you manage from the Profile tab. You can't pause a subscription, so a break means cancelling and subscribing again later. Other options are in my list of snoring apps with no subscription.

Privacy

Every App Store listing has a privacy label. The developer fills it in, and Apple sorts the answers into three tiers: data used to track you, data linked to you, and data not linked to you. Apple's developer page makes developers responsible for keeping those answers accurate.

What ShutEye's label declares

The first tier, Data Used to Track You, lists Identifiers. Apple defines tracking as linking data from an app with other companies' data for targeted ads or ad measurement, or sharing it with a data broker. Data Linked to You lists Identifiers as well, namely User ID and Device ID, for analytics.

Four categories sit under Data Not Linked to You. Health & Fitness and User Content (Audio Data) are declared for app functionality, and Usage Data and Diagnostics for analytics. An Audio Data entry means the developer declared that it collects audio. On its own, it doesn't tell you that every recording leaves your phone.

What ShutEye's privacy policy allows

ShutEye's developer, Enerjoy, covers the app with one privacy policy, last updated 10 September 2026. It says Enerjoy collects the sleep data you provide and, on iPhone, Apple Health data you choose to share, such as heart rate, sleep, respiratory data and blood oxygen. It uses Health data to build plans personalized for you. It uses your information to run and improve its services and AI features, with aggregated or de-identified data where appropriate, and for research and development.

The same policy says Enerjoy won't use or disclose health and fitness data to third parties for advertising, marketing or data mining, and never shares Health data with advertising partners. It does share personal information with service providers for hosting, payments and support, and it names Facebook, Firebase, Google, AppsFlyer and OpenAI among them. If you join its IKEA collaboration, which is opt-in, your sleep data goes to IKEA at the end for product recommendations. Enerjoy keeps personal information as long as it's reasonably needed, while it has a business need, or as the law requires. ShutEye's FAQ adds that it doesn't sell personal data, encrypts data at rest and in transit, and offers a Face ID or passcode lock.

Accounts

ShutEye's help center describes sign-up with email, Apple ID, Facebook or Google, and each method creates its own account, so data doesn't carry over between them. Its FAQ says the app tracks sleep offline and waits for a connection to sync and to load cloud-based insights.

Snore Timeline has no account, no server and no analytics SDK, so recordings and results stay on your phone until you export them. Of the 14 apps I checked, four declare Data Not Collected, and Snore Timeline is the one among those four with no purchases of any kind. 14 snoring app privacy labels compared has the full list.

Snore tracking depth

Both apps pick out snoring through the phone's microphone, and both give the night a sleep score. What they show you afterward differs.

ShutEye

ShutEye's how-it-works page describes a snoring report built around a graph of your snoring decibels across the night, with an analysis of how long and how loud you snored. It detects snoring, sleep talking, breathing changes, sleepwalking and coughing, and keeps the clips in your sleep report so you can replay and share them. Its help center describes a daily sleep score from 0 to 100 based on duration, efficiency and consistency, plus trend analytics that pick out patterns such as caffeine's impact and suggest changes.

One limit from the FAQ is worth knowing. If you share a bed, the app can't tell your sleep data apart from a partner's.

The FAQ reserves advanced sleep tracking and personalized insights for subscribers, and the how-it-works page pitches the 7-day trial as the way to track your sleep cycles and check your sleep score.

Snore Timeline

Snore Timeline records the whole night through the phone microphone, or through AirPods and other Bluetooth mics. Every sound gets processed as it arrives, with no periodic sampling, and each detection lands on a timeline you can zoom from 1-second bars out to 1-hour ticks. Tap any point and you hear that moment.

Snores in a row form an episode, and 30 seconds of quiet ends it. Each episode lists its duration, snore count, peak and average dB, rhythm class, and a plain-English summary such as "Heavy snoring for 22 minutes with one breathing disruption." The timeline and playback guide and the episodes guide explain how to read one.

Each night also gets a sleep score from 0 to 100, and snoring and breathing disruptions count against it. To test a remedy, you tag nights with any of 23 built-in sleep factors, such as Mouth Guard, Nasal Strips or Slept on Side, or with ones you create. Once you have 5 recorded nights, the app compares them and ranks what helped. Each factor gets a result after 3 recorded nights with it and 3 without. The test a remedy guide walks through it.

Sleep stages without a wearable

Neither app needs a watch or ring to estimate sleep stages. ShutEye's FAQ says it tracks sleep with the phone's sensors, microphone and accelerometer, monitoring movement and sounds, and its report sorts the night into light, deep and REM sleep.

Snore Timeline estimates Awake, Light, Deep and REM from the audio alone. On the nightly summary, the snoring chart switches between loudness and snores per minute, and a band of your sleep stages runs underneath it, so you can see whether your snoring clusters in light, deep or REM sleep. Tap a moment on the hypnogram and the snoring chart marks the same time.

If you wear something, stage data from Apple Watch, Oura, Garmin, Whoop and Ultrahuman comes in through Apple Health. When a night has data from more than one source, each source keeps its own stage timeline, so you can compare them side by side. ShutEye's FAQ says it pulls sleep and health data from Apple Health too. Stages from a phone are estimates, and Apple Watch & biometrics covers what each wearable adds.

Sounds, stories, and alarms

ShutEye was built around sound, and this is where it does the most. The App Store description leads with a large library of sleep sounds and ambient noise, plus bedtime stories to ease you into sleep. Its help center counts more than 70 ambient sounds, naturescapes and ASMR tracks, which you can mix yourself, along with meditation courses, breathwork, and CBT-i programs for insomnia.

Google Play names rain, thunder, ocean, fan, forest, fireplace, wind and bird sounds, and you can save favorite mixes for each night. On its home page, ShutEye frames the product around four pillars: sleep tracking, soothing sounds, a smart alarm, and a personalized sleep plan.

Snore Timeline plays nothing to help you drift off. If falling asleep is your problem, ShutEye is the one to open. The one sound Snore Timeline makes during the night is the Snore Nudge tone, which gets one step louder each time a nudge doesn't help. You can swap it for a silent iPhone vibration or a wrist tap, or use any mix of the three.

Both have a smart alarm. ShutEye's FAQ says its alarm wakes you in your lightest sleep phase. Snore Timeline's Smart Wake Up Alarm wakes you in light sleep within a 15, 30 or 45 minute window you set, with the option of a silent tap on Apple Watch. Snore Timeline vs BetterSleep looks at another sound-first sleep app.

Breathing pauses and sleep talking

Breathing changes are on the list of sounds ShutEye's how-it-works page says it detects, and the page describes a sleep apnea risk report built from breathing and snoring patterns. When the app picks up signs like loud snoring, choking sounds or pauses in breathing, its FAQ says it may suggest you get a medical opinion.

My app's rule is public. It waits for a minute or more of audible breathing, then watches for 10 or more seconds of silence ended by a sound such as a loud snore, a gasp or a breath. Matches show up on the timeline as breathing disruptions, and you can play each one. Keep the phone 1 to 2 feet from your head so the mic can hear you breathe. It hasn't been clinically validated, and it's not a medical device. Each step is in the breathing disruptions guide, and my guide to apps that flag breathing pauses compares others.

Both apps catch sleep talking. ShutEye files the clips with its sleep recordings, while Snore Timeline marks sleep talking on the timeline next to snores, gasps and coughs. My sleep talking recorder guide covers setup for catching quiet speech.

Watch, Android, export

Apple Watch

An Apple Watch app comes bundled with Snore Timeline on iPhone. From your wrist you can stop a recording, get a Snore Nudge tap when you snore or a Smart Wake Up Alarm tap in the morning, and see live heart rate and HRV while you record. Heart rate, HRV, respiratory rate, blood oxygen and wrist temperature appear next to your snoring. Recordings start on the iPhone, though. The wrist taps also work on Garmin, Fitbit, Huawei and other watches that show iPhone notifications. Data from Apple Watch, Oura, Whoop, Garmin and Ultrahuman comes in through Apple Health and feeds the sleep score, recovery score and hypnogram. Does Apple Watch track snoring? covers what the Watch can and can't hear.

ShutEye's FAQ says there's no dedicated ShutEye app for Apple Watch, and that it takes Watch data only through Apple Health. Its App Store listing names iPhone, Mac and Apple Vision under compatibility.

Android

Both run on Android. On Google Play, ShutEye shows 4.4 stars from 110K reviews and 10M+ downloads, with in-app purchases. Snore Timeline's Android version records from the phone mic and keeps the same timeline, episodes, breathing disruption flags and sleep stages. Its Watch app stays iOS only, and it reads and writes Health Connect in place of Apple Health.

Export

In ShutEye you can replay recordings and share them with friends, and the App Store description says it saves your sleep sessions to Apple Health.

Snore Timeline exports a ZIP of CSV files (nightly summary, sleep stages, detected events, watch biometrics) plus episode clips or the full-night recording. The files land in the Files app on iPhone or in Downloads on Android. The export guide covers building a report for a doctor.

Which one to pick

Pick ShutEye if

• You struggle to fall asleep and want sleep sounds, bedtime stories, meditation and CBT-i programs in the same app as your tracker.
• You'd like an insomnia risk assessment and a dream journal next to your snoring clips.
• You put weight on a long track record of user reviews, and ShutEye has 350,000 ratings at 4.8 on the App Store.

Pick Snore Timeline if

• You want no subscription, no in-app purchases and an App Store label that reads Data Not Collected. ShutEye sells Premium and lists Identifiers under Data Used to Track You.
• You want to replay any moment of the night, and export CSV files and the full-night audio, at no cost. ShutEye keeps clips of the sounds it detects.
• You wear an Apple Watch and want an app on it, with live heart rate and HRV, a tap when you snore, a silent alarm tap and a stop button. ShutEye has no Watch app [3].

ShutEye's 350,000 ratings dwarf Snore Timeline's 281. Snore Timeline reached the App Store in September 2025, ShutEye in December 2019, and I build it on my own with no outside funding and no marketing budget.
