How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.
Key takeaways
- Your phone tracks sleep with its microphone, accelerometer and sonar: no watch required.
- Sleep Cycle Premium ($39.99 per year) is the best-known phone-only tracker with smart wake-up.

The best sleep tracker apps without a watch
Your phone already sits on your nightstand. Here is what the watch industry does not advertise: that phone has a microphone that hears your breathing, an accelerometer that feels your movement, and in some apps a sonar mode that senses you without touch. Phone-only sleep tracking is not a compromise; for many people it is more comfortable and more consistent than wearing a watch to bed. These eight apps do it well.
#1
Sleep Cycle
Best for: iPhone and Android users who want the best-known phone-only sleep tracker
Visit sleepcycle.com
Starting price$39.99/year (Premium)
Free planYes
Sleep Cycle pioneered phone-only sleep tracking: place the phone on your nightstand, and its sound analysis tracks your sleep phases, waking you during light sleep within a customizable window. Premium ($39.99 per year, per multiple current listings of the site price) adds long-term trends, comparative statistics, snore and sleep-talk recording, heart rate measurement and online backup. The free version covers the core: tracking, basic stats and the smart alarm.
The honest catch is the shared bed. The microphone hears everyone in the room, so a partner's snoring or movement pollutes your data. Sleep Cycle also needs charging access by the bed since it runs all night. For solo sleepers who want the classic experience, it remains the reference app.
What we like- Premium at $39.99 per year is reasonable
- Patented sound-based analysis with smart wake-up windows
- Long-term trends, snore detection and sleep notes on Premium
Watch out for- Free version is limited to basic tracking and alarm
- Works best when you sleep alone (a partner confuses the microphone)
Starting priceSee website (one-time license key, not a subscription)
Free planYes
Sleep as Android is the veteran: over a decade of development, 10 million-plus installs, and a feature list no rival matches. It tracks via accelerometer, microphone or contactless sonar (using inaudible sound waves, so the phone does not even need to be in bed), and the alarm options range from gentle nature sounds to CAPTCHA tasks that force you awake. The base app is free; a one-time paid license opens everything with no subscription.
The honest catch is the learning curve. The settings menus are legendary for their depth, which means also for their intimidation factor. It is Android-only, so iPhone users should look at Sleep Cycle or Pillow. For the Android tinkerer who wants every option, nothing else comes close.
What we like- One-time license key instead of a subscription
- Sonar mode tracks without the phone in bed
- Enormous feature set (CAPTCHA alarms, anti-snoring, jet lag tools, Spotify alarms)
Watch out for- Android only
- The interface is famously dense and dated
#3
Pillow
Best for: iPhone users who want sleep tracking deeply integrated with Apple Health
Visit neybox.com
Starting priceSee website
Free planYes
Pillow is the iPhone-native answer: automatic sleep detection, sleep stage analysis, and deep integration with Apple Health so your sleep data flows into the rest of your health picture. The interface is calm and readable, a contrast to the denser Android-first apps. The free version covers core tracking; a premium subscription adds full analysis and history.
The honest catch is platform and pricing opacity. Pillow is iOS-only, and the premium price is presented in-app rather than on a public pricing page, so check the App Store listing before committing. For iPhone users who live in Apple Health, though, it is the most natural fit.
What we like- Clean iPhone-native design with Apple Health and HealthKit sync
- Automatic sleep detection
- Detailed sleep stage analysis and trends
Watch out for- IOS only
- Premium features sit behind a subscription whose price is shown in-app
#4
SleepScore
Best for: Users who want a simple sleep score and personalized improvement advice
Visit sleepscore.com
Starting priceSee website
Free planYes
SleepScore comes from sleep science rather than app development: its sonar tracking was developed with researchers, and the app emphasizes a single understandable sleep score plus personalized advice for improving it. If other apps drown you in graphs, SleepScore's guidance-first approach is refreshing. The free tier provides core scoring; premium adds deeper insights.
The honest catch is the alarm. SleepScore is a tracker and coach first, a smart alarm second; if waking gently is your priority, Sleep Cycle does it better. Pricing is also handled in-app. Choose SleepScore when the question is "how do I sleep better" rather than "when do I wake up."
What we like- Sonar-based tracking developed with sleep researchers
- Clear sleep score with actionable recommendations
- Free version provides core scoring
Watch out for- Advanced insights and history sit behind a subscription
- Less of an alarm clock than Sleep Cycle or Sleep as Android
#5
Rise
Best for: People who want to fix their sleep schedule using sleep debt science
Visit risescience.com
Starting priceSee website
Free planFree trial
Rise takes a different angle: instead of obsessing over last night's graphs, it calculates your sleep debt and predicts your energy windows, telling you the ideal bedtime and when you will feel sharpest. It is built on sleep science research around circadian rhythms, and for chronic under-sleepers the debt framing is more motivating than any chart. A free trial lets you test the approach.
The honest catch is that Rise is a coach, not a laboratory. If you want granular sleep stage data and snore recordings, look elsewhere. Pricing is presented in-app, so verify before subscribing. For the person whose real problem is an erratic schedule, Rise addresses the cause while trackers merely document it.
What we like- Unique focus on sleep debt and energy scheduling
- Tells you when to sleep and when you'll feel alert
- Clean, motivating interface
Watch out for- Subscription pricing shown in-app
- Less raw tracking detail than Sleep Cycle or Sleep as Android
#6
SnoreLab
Best for: Snorers who want to measure, track and reduce their snoring
Visit snorelab.com
Starting priceSee website
Free planYes
SnoreLab does one thing: it listens all night, detects snoring episodes, and gives you a Snore Score each morning. Where it earns its place is the remedy tracking: log what you tried (side sleeping, nasal strips, mouth tape) and see the score change over nights. For couples where snoring is the actual problem, this focused feedback loop beats any general tracker. The free version records and scores; premium adds history and analysis.
The honest catch is scope. SnoreLab will not give you sleep stages, smart alarms or energy predictions. It is a specialist instrument. Pair it with a general tracker, or use it alone if snoring is the whole question.
What we like- Purpose-built snore detection with a snore score
- Tracks remedies (nasal strips, mouthpieces, position) against results
- Free version records and scores
Watch out for- Narrow focus: it is a snoring tool, not a general sleep tracker
- Premium features behind a subscription
#7
ShutEye
Best for: People whose main problem is falling asleep, not tracking sleep
Visit shuteye.ai
Starting priceSee website
Free planFree trial
ShutEye attacks the other end of the night: the hour you spend staring at the ceiling. Its library of sleep sounds, bedtime stories and guided relaxations is designed to shorten sleep onset, and it bundles sleep tracking so you can see whether the content actually helps. For anxious minds and restless sleepers, the wind-down content matters more than another graph.
The honest catch is the tracking depth. ShutEye's sleep analysis is thinner than Sleep Cycle's or Sleep as Android's; you are paying for the content library. Pricing appears in-app, so check before subscribing. If falling asleep is your bottleneck, start here; if analyzing sleep is, start elsewhere.
What we like- Sleep sounds, stories and guided relaxations aimed at falling asleep faster
- Includes sleep tracking alongside the content
- Free trial to test the library
Watch out for- Content library is the product, so trackers get less depth
- Subscription pricing shown in-app
#8
BetterSleep
Best for: Users who want relaxation sounds plus straightforward sleep tracking
Visit bettersleep.com
Starting priceSee website
Free planYes
BetterSleep (the app formerly known as Relax Melodies) pairs one of the largest relaxation sound libraries with sleep tracking and smart alarm features. Mix your own soundscapes, fall asleep to stories or meditations, and wake to a gentle alarm. The free version covers a solid selection of sounds; premium opens the full library.
The honest catch mirrors ShutEye: the content is the star, the tracking is the supporting act. If you want deep sleep analytics, the dedicated trackers do more. But for the large audience whose sleep problem is really a relaxation problem, BetterSleep's free tier is one of the best deals in the category.
What we like- Large library of sounds, meditations and bedtime stories (formerly Relax Melodies)
- Free version is genuinely useful
- Combines wind-down content with tracking
Watch out for- Premium subscription opens the full library
- Tracking features are secondary to the content
How we chose
We started with the actual search: best sleep tracker app without watch, sleep tracking app no wearable, phone-only sleep tracker. For each candidate we verified the phone-only tracking method (microphone, accelerometer or sonar) and checked the vendor's site or app store listing for pricing. Where pricing lives only in-app, we wrote "See website" rather than repeating third-party figures. Apps requiring a wearable were excluded by definition.
Frequently asked questions
Can a phone track sleep accurately without a watch?
Reasonably. Phones use microphone, accelerometer and sometimes sonar to detect movement and breathing patterns, which correlate with sleep stages. They are less precise than clinical devices but good enough for trends, consistency and smart alarms. Consistency matters more than precision.
Do sleep tracking apps drain the battery overnight?
They use significant battery running all night, which is why every app here recommends charging while tracking. Place the phone on your nightstand plugged in. This is the main practical requirement of phone-only tracking.
Will a sleep app work if I share a bed?
Partially. Microphone-based apps (Sleep Cycle, SnoreLab) hear both people, which pollutes the data. Sonar or accelerometer modes (Sleep as Android's sonar) are less affected. Solo sleepers get the cleanest data from any app.
Is Sleep Cycle Premium worth $39.99 per year?
If you use the smart alarm daily and care about long-term trends, snore detection and sleep notes, yes: it is mid-priced for the category. If you only need basic tracking and a smart alarm, the free version suffices.
What is the best free sleep tracker without a watch?
Sleep as Android (free base app on Android) and Sleep Cycle (free tier on iOS and Android) are the strongest free options. BetterSleep's free tier is best if relaxation content matters more than tracking depth.
Do these apps replace a sleep study?
No. Consumer sleep apps estimate sleep stages from movement and sound; they cannot diagnose sleep apnea or other disorders. If you snore heavily, gasp, or feel exhausted despite adequate sleep, see a doctor.
Phone-only tracking methods explained
Phone sleep apps use three sensors. The microphone hears breathing, snoring and movement sounds; it is the most common method and the most affected by partners and room noise. The accelerometer feels movement when the phone is on the mattress; it needs the phone in bed with you. Sonar (Sleep as Android, SleepScore) emits inaudible sound waves and reads the reflections; it works contact-free from the nightstand and is the most partner-resistant.
No method matches a clinical sleep study, and none needs to for the job most people want: building consistent habits, waking gently, and noticing when something changes. Pick the method that fits your bedroom reality, then pick the app that implements it best.
