Best sleep tracking apps, compared
Six trackers, each with the one thing it is genuinely best at, and the catch that usually goes unmentioned.
Which sleep tracking app is best? Sleep Cycle is the strongest all-rounder. SleepTrace is the one that records and labels your snoring on its free plan (3 playable clips a month). SnoreLab is built for actively reducing snoring. Sleep as Android is the pick on Android. Pillow suits people who already wear an Apple Watch. Oura gives body data no phone app can. Which is “best” depends entirely on whether you want to hear your night, measure your body, or fix your snoring.
The picks
What each one is best at
-
Best all-rounderiOS · Android
Sleep Cycle
The most established phone-based tracker, with sleep stages, a large sleep-aid library and a 'Who's Snoring?' feature that separates two people in one bed.
The catch: The App Store text puts snore detection under Premium ("Unlock all sleep aids, snore detection & more"). The site advertises a 30-day free trial; check the listing for current prices.
-
Best free snoring detectioniOS · Android
SleepTrace
Records and labels every snoring episode with a decibel reading on the free plan (3 clips a month are playable for free, unlimited with Premium), and estimates sleep stages from the same audio every 30 seconds. The analysis runs on the device.
The catch: launched on iPhone in July 2026 (Android followed in autumn 2026), it cannot tell two snorers apart, and stages are an estimate from sound.
-
Best for actively reducing snoringiOS · Android
SnoreLab
Built entirely around the snoring problem: a Snore Score, a remedy log so you can see what actually helped, and airway exercises in the separate SnoreGym app.
The catch: Its App Store listing declares advertising and offers Premium as a subscription or a one-time purchase; it is a snoring log, not a full sleep tracker.
-
Best on AndroidAndroid
Sleep as Android
Its vendor site lists sleep talk and snoring recording, snoring stats and room noise stats, and it works with smart watches including Wear OS.
The catch: Android only, there is no iPhone version, and its vendor page states no price.
-
Best if you already wear an Apple WatchiOS
Pillow
Leans on the watch's accelerometer and heart-rate sensor for stage detection and presents clear colour-coded graphs, with on-device detection of snoring, sleep talking and other sounds.
The catch: Its App Store text lists unlimited sleep history and sound recordings under Premium (the page shows an annual plan at $39.99), and heart-rate analysis needs the watch.
-
Best body data, if you will wear somethingHardware · iOS · Android
Oura Ring
A ring whose support page for the Oura Ring 4 lists PPG, temperature and motion sensors, measuring heart rate around the clock, HRV and respiration during sleep, blood oxygen overnight and body temperature variations: data no microphone can produce.
The catch: A hardware purchase, plus an Oura membership for the full insights (the membership page listed $5.99 a month in the US on 2 November 2026). The sensors listed on its support page include no microphone, so no snoring, sleep talking or room noise.
A note on bias. SleepTrace is our app, so read this with that in mind. We have given ourselves exactly one category, free snoring detection, because that is the one we can actually defend. For an all-rounder, on Android, with a watch, or for body metrics, the better pick is one of the others. Details for Sleep Cycle, SnoreLab, Pillow, Sleep as Android and Oura were re-checked on 2 November 2026 against each product’s own site, store listing or support page (linked above). They change often, so verify anything decision-critical at the source.
How to choose
Start with the question, not the app
“Do I snore, and how badly?” You need a microphone. Any of the phone apps here will record it; the difference is whether that costs money and whether the snoring is placed inside your sleep stages.
“How well did I actually sleep?” Sleep stages are the answer, and every app here estimates them somehow: from audio, from motion, or from a wearable's sensors. None of them matches a sleep lab.
“How is my body recovering?” That means heart rate, HRV and blood oxygen, which need a sensor on your skin. No phone app can do it. Buy a ring or a watch.
“What do real users complain about?” We read the ratings and the newest written reviews: Sleep Cycle, ShutEye and SnoreLab, plus the alternatives compared.
“How do I snore less?” That is a different job from measuring: you want a remedy log and exercises, which is SnoreLab's territory.
Which sleep tracking app is free?
A sleep tracking app free of charge usually means one of three things: a free plan that never ends but holds some features back, a time-limited trial, or a free download with in-app purchases. The free version worth keeping is the one that answers your question. For snoring, SleepTrace records every night free and lets you play back 3 clips a month. Sleep Cycle advertises a 30-day free trial on its site. Pillow is a free download with in-app purchases, and its listing puts sound recordings and unlimited history under Premium. The Apple Watch has built-in sleep tracking once you own the watch, and Apple describes stages, a Sleep Score, heart rate and respiratory rate on its support page.
On Android, see sleep tracking apps for Android. If a watch is part of the plan, snoring apps for Apple Watch and Garmin covers what the watches record. For the iPhone side, our longer guide to the best sleep tracking app for iPhone goes further.
Best sleep tracking app on Reddit? How to read the recommendations
People often ask which sleep tracking app Reddit recommends, and the threads are full of opinions. None of them is a source for this page, so we cannot tell you what Reddit recommends. If you read one, ask three things. Which phone or watch did the writer use, and what kind of night did they test? Is the writer connected to the app, for example as its developer? Does the app still work as described in its store listing, given that an app called free two years ago may not be today? A recommendation that survives those questions, plus one night of your own testing, is worth more than any ranking.
Common questions
Choosing a sleep app, answered
SleepTrace estimates sleep phases with just a phone on the nightstand: an on-device model reads the night's audio and estimates the phase (awake, light, deep, REM) every 30 seconds, alongside snoring, talking and coughing clips you can play back, and apparent breathing pauses flagged with a timestamp. No wearable is needed. Without a body sensor the phases remain an estimate; medically robust staging requires a sleep lab.
For most people wanting one app that does everything reasonably well, Sleep Cycle is the strongest all-rounder: sleep stages, a large sleep-aid library, and it runs on both iOS and Android. Its limitation is that snore detection is listed under Premium.
SleepTrace records and labels snoring on its free plan, with a decibel reading per episode, estimated sleep stages and 3 playable clips a month. Sleep Cycle's App Store text lists snore detection under Premium, and SnoreLab's App Store listing declares advertising and offers Premium as a subscription or a one-time purchase. If hearing your own snoring without paying is the goal, that is the practical difference.
Sleep as Android is built only for Android: its vendor site lists sleep talk and snoring recording, snoring stats and room noise stats, and it works with smart watches including Wear OS. SleepTrace is available on Android too (Google Play) and records the night as audio. Sleep Cycle runs on both platforms.
No. Phone-based apps track sleep stages and night sounds with nothing on your body. What they cannot do is measure heart rate, HRV or blood oxygen, those need a sensor touching you. If recovery metrics matter to you, a ring or watch is the right purchase; if hearing your night matters, a phone app is.
All consumer trackers produce estimates rather than clinical measurements. A 2026 study in Frontiers in Neuroscience (PMID 41782921, DOI 10.3389/fnins.2026.1693860) tested a cardiorespiratory chest-patch wearable, not a phone app: it reached 77.1% accuracy for four-class sleep staging against expert scoring of home EEG recordings in 17 people with insomnia and depressive symptoms. Estimates like this can help you spot patterns over weeks, but they are not a diagnostic instrument, phone or wearable alike.
It depends on what the free version includes. SleepTrace's free plan records every night and plays back 3 clips a month. Sleep Cycle advertises a 30-day free trial. Pillow is a free download with in-app purchases, with sound recordings under Premium. The Apple Watch has built-in sleep tracking once you own the watch.
We do not use Reddit threads as a source, so we cannot say what they recommend. When you read such a recommendation, check its date, whether the person has a connection to the app, which devices they tested, and whether the claim holds in the store listing.
