A sleep score app turns last night into one number. That is the whole product: hours, stages, wake-ups and timing, boiled down to something you can read before your eyes fully open. The catch is that every app uses a different recipe, so the same night can be an 86 in one app and a 64 in another, and neither is lying. This page explains what actually goes into a sleep score, then ranks the seven apps we would put on a phone in 2026, on iPhone and on Android.
If you specifically want the Apple Watch angle, including Apple’s own 50/30/20 recipe, that lives in sleep score app for Apple Watch. If you want full-fat sleep trackers with smart alarms and audio, see the best sleep tracking apps roundup. This page is the score itself.
Short verdict: If you wear an Apple Watch, start with Apple’s free native score, then add Sleep by Fitcoin or Fitcoin if you want stages weighted in the headline number. On Android, anything that reads Health Connect works with whatever watch you already own; Fitcoin does. Buy Whoop or Oura only if you want their hardware, not just their score. And whatever you pick, pick one. Four scores for one night is a group chat, not insight.
Disclosure: Fitcoin and Sleep by Fitcoin are our products. We are not affiliated with Apple, Whoop, Oura, SleepScore Labs, Pillow or Sleep Cycle. Where our apps appear in this list, we say so and explain the trade-offs like everyone else’s. Every score described below is a wellness estimate for general fitness. None of them is a medical device and none diagnoses illness.
What a sleep score actually is
A sleep score is a 0–100 summary of one night, computed from whatever data your device recorded. It exists because raw sleep data is unreadable at 7am. Nobody wants to weigh 6 hours 48 minutes against 14% deep and two long wake-ups before coffee. A score does the weighing for you, and a decent one is consistent enough that a trend means something after two weeks.
What a sleep score is not: a diagnosis, a grade of you as a person, or comparable across apps. An 80 in Sleep Cycle and an 80 in Whoop were built from different ingredients. Treat each app’s score as its own currency.
How apps compute it: the four ingredients
- Duration. Time asleep versus a target, usually anchored around 7–9 hours for adults. Almost every app makes this the biggest slice. Apple gives it up to 50 of 100 points.
- Stages. Deep and REM as a share of the night, estimated by a wearable from movement and heart rate. Fitcoin gives deep and REM 25 points each when stages exist. Apple shows stages but does not score them.
- Physiology and HRV. Some scores fold in overnight heart-rate dip, HRV or respiratory rate. Whoop leans on this heavily; its sleep score then feeds Recovery, which we unpack in Whoop Recovery explained.
- Consistency and continuity. Regular bedtimes and fewer wake-ups. Apple scores consistency at up to 30 points; Fitcoin applies a mild 7-night regularity multiplier instead of a fixed slice.
Which ingredients an app can even use depends on hardware. A watch worn overnight produces stages and heart data. A phone on the mattress or bedside table produces duration, disturbances and sound. That is why the phone-only apps below score behaviour, and the wearable apps score physiology.

1. Sleep by Fitcoin: free, stage-weighted, ours
Sleep by Fitcoin is our free companion app, currently rolling out on iPhone and Android, and yes, it is ours, which is exactly why it is at the top of our list and why you should apply salt. What it does: reads last night from your watch or tracker, shows hours, REM, deep, core and awake, and prints a 0–100 SleepScore. Nights are kept in a history, the week shows as an hours chart, and your Fitcoin friends appear ranked on last night’s score, which turns bedtime into a mild competitive sport. It does not start a session, run a microphone, or write sleep back into your health data. There are no ads. If you already use the main Fitcoin app it is the same account; if not, it works on its own.
The honest limits: it needs a wearable that records sleep, because the score weights stages, and it is deliberately simple. No smart alarm, no snore audio, no white noise. If you want those, Pillow or Sleep Cycle below are the better fit. The main Fitcoin app, which is already in the stores, computes the same style of SleepScore today and can earn you up to 10 Fitcoin for the night.
2. Apple’s native Sleep Score: free and already on your wrist
From watchOS 26, Apple Watch prints its own 0–100 Sleep Score: up to 50 points for duration, 30 for bedtime consistency across recent nights, 20 for interruptions. Stages appear in the chart but get no slice of the score. It is free, reliable and scores behaviour rather than architecture, which for most people is the right first coach: sleep long enough, on a schedule, without waking up. The full breakdown, including what the Very Low to Very High labels mean, is in our Apple Watch sleep score guide.
3. Whoop: the score that argues with your calendar
Whoop scores sleep you got against sleep it thinks you needed, and need moves with strain, debt and naps. Seven hours after a brutal training day can score worse than seven hours after a rest day, on purpose. That sleep performance then feeds the morning Recovery colour. It is the most opinionated score here and the most expensive way to get one, because it requires the strap and a subscription. Worth it if you train seriously and will wear the strap 24/7; overkill if you just want a number.
4. Oura: the most comfortable overnight hardware
Oura’s sleep score blends duration, efficiency, stages, timing and restfulness, and the ring is by far the easiest thing on this page to actually sleep in. The trade is cost: a ring plus a monthly subscription. If a watch on your wrist at night drives you mad, Oura is the comfortable answer. How the ring compares with wrist hardware is covered in Oura vs Apple Watch.
5. SleepScore: no wearable required
SleepScore (from SleepScore Labs) uses the phone itself, bouncing inaudible sonar off you to estimate breathing and movement, then scores the night. No wearable, nothing on your body, and the science pedigree is real. The limits are physics: it works best with the phone positioned correctly on a bedside table, it struggles with two people in the bed, and stage estimates are rougher than a wearable’s. A good pick if you refuse to wear anything at night.
6. Pillow: the Apple Watch power tool
Pillow is an iPhone and Apple Watch app with its own sleep quality score, stage charts, heart-rate overlays and snore audio. It can run watch-based or phone-only. The free tier is genuinely usable; the subscription unlocks history and audio. If you want more detail than Apple’s native score without buying new hardware, Pillow is the sensible upgrade.
7. Sleep Cycle: the smart alarm that grew a score
Sleep Cycle started life as a smart alarm and still wakes you in a light phase, which for some people is the entire value. Its sleep quality score comes from duration, regularity, movement and snoring picked up by the microphone, on iPhone or Android, no wearable needed. The score is the least physiological on this list, but the alarm plus long-run regularity graphs keep it on phones for a reason.
Sleep scores on Android specifically
Android’s sleep story runs through Health Connect. Wear a Galaxy Watch, Pixel Watch, Fitbit or most other bands, let them write sleep into Health Connect, and any app with permission can score it. Fitcoin does exactly this on Android today: stages when your watch provides them, duration and continuity when it does not. Samsung Health scores Galaxy Watch nights natively, and Sleep Cycle and SleepScore work phone-only on Android with no watch at all.
The one thing to avoid on Android is letting two apps write sleep for the same night into Health Connect, then reading a third app’s score of the mess. One writer, one scorer, and the trend will actually mean something.
How to choose in 30 seconds
- Apple Watch owner, want free: Apple’s native score, plus Sleep by Fitcoin or Fitcoin if you want stages weighted.
- Android with any watch: Fitcoin via Health Connect, or Samsung Health if you are all-in on Galaxy.
- Refuse to wear anything at night: SleepScore or Sleep Cycle on the phone.
- Training seriously and money is no object: Whoop or Oura, whose scores feed proper recovery systems.
- Want a smart alarm as the main event: Sleep Cycle, and treat the score as a bonus.
Then commit for two weeks. A sleep score is only useful as a trend against your own baseline. Chopping between apps resets the baseline and teaches you nothing except that recipes differ, which you now already know.
Frequently asked questions
What is a good sleep score?
It depends on the app, because every app uses a different recipe. As a rough rule, most 0–100 scores treat 80+ as a solid night and anything under 60 as short, broken or badly timed sleep. The useful comparison is you versus your own last fortnight inside one app, not your 74 versus a friend’s 84 in a different app.
What is the best free sleep score app?
If you have an Apple Watch on watchOS 26, Apple’s built-in Sleep Score is free and already on your wrist. Sleep by Fitcoin is our free companion app that adds a stage-weighted SleepScore and friends, and the main Fitcoin app (free) computes a SleepScore that can also earn rewards. Sleep Cycle and Pillow have usable free tiers with subscriptions on top.
Can I get a sleep score on Android?
Yes. Wear any watch or band that writes sleep into Health Connect (Samsung Galaxy Watch, Pixel Watch, Fitbit and others), then use an app that reads it. Fitcoin computes a 0–100 SleepScore from Health Connect on Android, Samsung Health scores nights from a Galaxy Watch, and Sleep Cycle works phone-only with the microphone.
Why do sleep score apps disagree with each other?
Different recipes. Apple weights duration, schedule consistency and awakenings. Stage-weighted apps such as Fitcoin give deep and REM their own slice. Whoop scores sleep you got versus sleep it thinks you needed. Same night, different question. Pick one headline score and follow its trend.
Do I need a wearable for a sleep score?
For a stage-based score, yes: stages come from a watch, ring or strap worn overnight. Phone-only apps such as Sleep Cycle and SleepScore estimate your night with the microphone or sonar instead. They can track duration and disturbances, but their stage estimates are rougher than a wearable’s.
Is a sleep score medical?
No. Every score on this page is a wellness estimate. None of them diagnoses insomnia or sleep apnoea. If you are persistently exhausted despite decent scores, speak to a GP, not an algorithm.
How we researched this: Written 16 August 2026 from Apple’s Sleep Score user guide (watchOS 26 duration / consistency / interruptions split), Whoop’s published sleep performance and Recovery documentation, Oura’s sleep score help pages, SleepScore Labs’ and Sleep Cycle’s public method descriptions, Pillow’s feature documentation, and Fitcoin’s own on-device SleepScore calculator, which we build. Third-party weights, prices and platform support change; confirm the live app before you subscribe. Fitcoin and Sleep by Fitcoin inclusion is ownership-disclosed. Wellness estimates only; not medical advice.
