Best Sleep Tracker Apps for Android (2026)

Quick Verdict

If you only install one app, make it Sleep as Android. It is the most capable tracker of the bunch: contactless sonar tracking, smart alarm, sound recognition, wearable support, and a free tier after the 7-day Premium trial. If that app feels like too much, Sleep Cycle is the simpler pick — put your phone on the nightstand and let it do the rest. And if your real problem is snoring, skip the general trackers entirely and get SnoreLab, the one app built specifically for it.

What a Phone App Can Actually Measure

Before comparing apps, it helps to know what your phone is really doing while you sleep. No phone app reads brainwaves, so none of them can measure sleep the way a lab or a high-end wearable does. They work with what the phone has: the accelerometer, the microphone, and sometimes sonar from the speaker.

From movement and sound, apps infer your sleep: when you fell asleep, when you woke up, how restless you were, and rough guesses at light versus deep sleep. Research on phone-based tracking puts total-sleep and wake detection around 80-90% accuracy — solid — but stage accuracy (telling REM apart from deep sleep) is weak. So read your nightly "deep sleep %" as a trend over weeks, not a diagnosis after one night.

It also helps to separate two kinds of apps that get mixed together in "best sleep app" lists:

• Trackers measure your night — movement, sound, snoring, trends. That is Sleep as Android, Sleep Cycle, Sleep Monitor, and SnoreLab.
• Sleep-aid apps mainly help you fall asleep with sounds, stories, and meditation, with lighter tracking on the side. That is ShutEye and BetterSleep.

Neither kind is a medical device. Every app on this list says so on its Play listing, and that matters: none of them can diagnose sleep apnea or any other condition. If you gasp awake, snore loudly every night, or feel exhausted after eight hours, see a doctor — don't let an app talk you out of it.

How We Chose

We read the top ranking pages on this keyword end to end, then opened the Play Store listing of every finalist and checked what the developer actually claims: sensor method, phone placement, free tier versus subscription, ads, smart alarm, sound recording, and medical disclaimers. The six apps below are the ones that earned their spot.

Comparison at a Glance

1. Sleep as Android — the most capable tracker

Sleep as Android has been around for over a decade and it shows: no other app on this list tries to do as much. You get three ways to track — phone on the mattress sensing movement through the accelerometer, contactless sonar from the nightstand (the phone plays quiet pulses and listens for the echo), or a paired wearable. It adds AI sound recognition that labels what it hears (snoring, talking, coughing), respiration analysis, and a smart alarm that wakes you inside a gentle window rather than at a fixed brutal minute.

Free vs paid: you get a 7-day Premium trial, then it drops to a free tier with an optional one-time upgrade for the full feature set. There is no forced subscription, which is rare in this category.

Standout: the integration list is enormous — Google Fit and Health Connect sync, Philips Hue lights, Spotify, Tasker automation — plus detailed graphs for anyone who loves data.

Downside: the settings menu is famously deep. Expect to spend one evening tuning it before it feels right. If you want "install and forget," this is not that app.

Best for: data lovers and anyone who wants the most complete phone-based tracking available on Android.

2. Sleep Cycle — the simplest reliable tracker

Sleep Cycle takes the opposite approach: phone on the nightstand (or the floor beside the bed — never under your pillow), and it listens. Using sound analysis it figures out when you fall asleep, how you sleep, and when you wake, then scores your night from 1 to 100. Its smart alarm, snore/talk/cough recorder, long-term trends, and built-in sleep sounds round out a tidy package, with Wear OS and Google Fit support if you own a watch.

Free vs paid: the free tier covers core tracking and the alarm; Premium adds deeper stats and sounds.

Standout: one independent tester ranked it best for tracking accuracy among the Android apps tried, and its interface is the easiest to read the morning after.

Downside: it keeps the microphone active all night, so the phone must stay on its charger. One review noted it missed some brief awakenings, and it is not the right tool if snoring analysis is your main goal.

Best for: people who want accurate, no-fuss tracking without wading through settings.

3. Sleep Monitor — the balanced all-rounder

Sleep Monitor sits comfortably between the two above: easier than Sleep as Android, more detailed than Sleep Cycle. Your phone goes next to the bed — no wearable needed — and the app records sleep stages, snoring, talking, and breathing sounds, then rolls it into a daily sleep score with weekly and monthly trend reports. A smart alarm, habit tagging (caffeine, exercise, screen time), and exportable reports complete the package.

Free vs paid: free with ads; the Pro subscription adds extended reports, data exports, and removes ads. Its listing describes it plainly as a wellness tool, not a medical device.

Standout: the weekly and monthly reports are genuinely useful for spotting patterns — like whether late coffee actually costs you deep sleep. Pairing it with a notes app works well for logging habits; our Google Keep alternatives roundup has good journaling options if Keep isn't your thing.

Downside: the free tier's ads can be annoying, and some of the most useful reports sit behind Pro.

Best for: anyone who wants solid tracking plus trend reports without the complexity of Sleep as Android.

4. SnoreLab — the snoring specialist

SnoreLab does one job and does it well: it records your night, detects snoring with dedicated algorithms, and gives you a Snore Score — a simple number that tracks how loud and frequent your snoring is over time. Its BreathFlow feature analyses breathing patterns for irregularities, and you can log remedies and lifestyle factors (a new pillow, less alcohol, nasal strips) to see what actually changes your score. With over 50 million nights monitored, it is the reference app for this niche.

Free vs paid: free to download with ads and in-app purchases; core recording and scoring work without paying.

Standout: the remedy-testing loop — change one thing, compare your Snore Score the next morning — turns vague "I think I snore less" into data. It can be useful material to bring to a doctor visit.

Downside: it is not a general sleep tracker; you won't get sleep stages or a full sleep score. And the listing is explicit: SnoreLab is not a medical device and cannot diagnose sleep apnea. Recordings of loud, irregular snoring are a reason to see a doctor, not a diagnosis.

Best for: snorers and their partners — and anyone whose doctor asked "how bad is the snoring, really?"

5. ShutEye — tracker meets bedtime companion

ShutEye blends the two categories: it tracks your sleep (light, deep, and REM estimates, daily sleep score, snore detection, trends, and reports) and it also helps you fall asleep, with sleep stories, guided meditation, breathing exercises, and a sound library you can mix — up to eight layers of rain, thunder, ocean, fan, and forest. The smart alarm wakes you during your lightest sleep stage for a gentler morning.

Free vs paid: free to download with no ads; a subscription opens the VIP library of stories and sounds.

Standout: if your problem is falling asleep rather than analysing sleep, the bedtime content is the point — the tracking is a solid bonus. Our best white noise apps for Android guide compares pure sound apps if you don't need tracking at all.

Downside: the best content is paywalled, and at roughly $60/year the subscription is one of the pricier options here. Power trackers will find its analytics thinner than Sleep as Android.

Best for: restless minds who want stories, sounds, and tracking in a single app.

6. BetterSleep — best for falling asleep faster

BetterSleep (formerly Relax Melodies) leans hardest into the sleep-aid side: 300+ high-quality sounds, sleep stories, and guided content you can mix into personal soundscapes, plus basic sleep tracking on top. With 25 million downloads it is one of the most-installed apps in this space, and its sound library is the reason why.

Free vs paid: a free tier covers the basics; a subscription opens the full library and tracking features.

Standout: the sound quality and variety beat every pure tracker here — if white noise, rain, and stories are what get you to sleep, nothing else on this list comes close.

Downside: tracking is secondary; don't install it expecting Sleep Cycle-level analytics.

Best for: people whose main problem is drifting off, not analysing the night after.

Prices, Pros and Cons

FAQs

Are free sleep tracker apps accurate?

They are reasonably good at detecting total sleep time and wake moments (around 80-90% accuracy in studies), but weak at telling REM from deep sleep. Treat nightly stage percentages as rough trends, not lab-grade measurements.

Can a sleep tracker app detect sleep apnea?

No. Phone apps can flag possible breathing irregularities, but every app on this list states it is not a medical device. If you snore loudly, gasp, or feel exhausted despite full nights, see a doctor — an app cannot diagnose apnea.

Where should I put my phone for sleep tracking?

It depends on the app. Sleep as Android can sit on the mattress and sense movement, or on the nightstand using sonar. Sleep Cycle and Sleep Monitor want the phone on the nightstand or the floor beside the bed — not under your pillow. Keep it plugged in overnight.

Do sleep tracker apps drain the battery?

Yes — the microphone or sonar runs all night, which uses real power. Every app on this list expects the phone to stay on a charger beside the bed during tracking.

Do I need a smartwatch for sleep tracking on Android?

No. All six apps here work phone-only using the accelerometer and microphone. A wearable can add heart-rate data for richer analysis, but it is optional, not required.

Final Recommendation

Start with Sleep as Android if you want the deepest picture of your nights and don't mind spending an evening setting it up. Choose Sleep Cycle if you want something that just works from night one. Add SnoreLab alongside either one if snoring is your concern — it answers a question the general trackers barely touch. And if your nights begin with an hour of staring at the ceiling, pair your tracker with BetterSleep or ShutEye for the falling-asleep part.

Whatever you pick, use it for trends, not verdicts. Compare this week to last month, watch what your habits do to your scores, and keep one foot in reality: a phone on your nightstand is a helpful observer, not a doctor.
