Sleep tracking apps turn a phone or a watch into a bedside recorder: hours asleep, restless spells, snoring, a score waiting at breakfast. This rating is for readers who want that data without buying a ring or a headband, and for anyone deciding whether a subscription already sitting on the card deserves another year.
Selection went by things that can be checked. How the app measures sleep: accelerometer, microphone, ultrasonic sonar, or heart rate from a watch. Whether it works without a wearable at all. What the money buys: one time purchase, monthly plan, annual plan, and what stays behind the paywall. Then the practical details a designer notices at 7 a.m.: legibility of the charts, smart alarm behaviour, audio clips of snoring, export for a doctor, sync with Apple Health or Health Connect, and how the developer answers email. Apps that had drifted into abandonment or lost their tracking features were left out.
Positions here move with community votes, so the order reflects what people actually keep on their phones rather than editorial taste. The cards carry the useful part: pros, cons, prices, contacts and reader reviews. Worth remembering that consumer sleep tracking apps estimate rather than measure stages, and none of them replaces a clinical sleep study.
Northcube's app has been on the App Store since 2009 and still sets the reference for phone based tracking. It listens through the microphone, with the accelerometer as an alternative, sorts the night into light, deep and REM, records snoring, coughing and sleep talking, then wakes the sleeper inside a chosen window. Premium runs about $39.99 a year and adds full statistics, snore detection, sleep programs and the SleepGPT chatbot; the free tier keeps basic tracking and the smart alarm.
It suits people who own no wearable, since the phone can sit on the nightstand instead of the mattress. Apple Watch owners feed heart rate and temperature in through Apple Health. Long time users grumble that features once bought outright moved behind the subscription, and microphone tracking reacts to a restless partner or a dog on the floor.
Urbandroid has been shipping this alarm clock since 2010 and it shows: the settings read like a control panel. Tracking runs from the accelerometer, from ultrasonic sonar through the speaker, or from a wearable, including Wear OS, Galaxy Watch and Garmin through Connect. Snoring detection, anti snore feedback, sleep talk recording, lullabies with binaural tones, Health Connect export and SleepCloud backup are all included.
The wake up CAPTCHA is the party piece: solve arithmetic, shake the phone or scan an NFC tag taped inside the bathroom before the alarm gives up. Payment is a lifetime unlock or a monthly plan, and the unlock has grown expensive over the years. Android only, and the depth of options will overwhelm anyone who wants one button and one graph.
Pillow, from Cyprus based Neybox Digital, is the iOS specialist: iPhone, iPad, Apple Watch, no Android build at all. With a Watch on the wrist it starts and stops on its own and pulls heart rate, HRV, respiratory rate and wrist temperature; without one, the phone goes on the mattress. Everything syncs to Apple Health, and the nap presets cover power nap, recovery nap and a full cycle.
Charts are the strong point: clean stage bars, mood notes after waking, audio clips of snoring or sleep talk. Premium unlocks unlimited history, trends, heart rate analysis and the whole audio library, billed monthly or yearly. Anyone who charges the Watch overnight loses the best half of the app, and Android readers can stop reading here.
AutoSleep is the anti subscription option: one purchase from Australian developer Tantsissa, no recurring fee, no advertising. It reads Apple Watch data and works out sleep without any button pressing, then reports time asleep, restlessness, sleeping heart rate dip, sleeping HRV and a readiness figure. A Sleep Bank chart tracks accumulated debt or credit, and the night hour settings handle shift patterns.
Data density is both the appeal and the obstacle. Most newcomers need the online guide before the rings and colours make sense. It sits alongside the same developer's HeartWatch, AutoWake and AutoSnore apps, each a separate purchase. Support goes through a form inside the app rather than a published address, and an Apple Watch is effectively mandatory.
Bodymatter, based in Newport Beach, built SleepWatch around a simple habit: wear the Watch, forget about it, read the summary at breakfast. The app scores each night, follows how consistent the sleep rhythm is, and pays unusual attention to the resting heart rate dip, a metric most rivals bury three screens deep. Nights without the Watch can be entered by hand. The App Store average sits near 4.7 across more than 300,000 ratings.
The free tier covers the basics, while premium adds trends, deeper analytics and full history. A sensible pick for readers who want the app to interpret the night in plain sentences instead of handing over raw graphs. Those who dislike recurring payments for their own data will find the paywall irritating, and there is no Android version.
SleepScore was spun out of ResMed in 2016 and now trades under the Sleep.ai name. Nothing touches the sleeper: the phone sends inaudible sonar from the nightstand and reads movement and breathing, so no strap and no device on the mattress. The company points at peer reviewed papers validating the measurement against polysomnography, which is a firmer claim than most app makers put forward.
The free version gives nightly scores and advice; the paid tier adds full history, correlations, exportable data and a report to hand a physician. Useful for anyone who suspects a breathing problem and wants a record before a clinic visit. The catch: sonar wants the phone plugged in and aimed correctly, and product recommendations lean towards partner merchandise.
RISE, from Rise Science, deliberately skips sleep stages. It tracks two figures instead: sleep debt built up over the past fortnight and circadian rhythm, then predicts when energy peaks, when the afternoon slump lands and when melatonin should start rising. Input can come from phone use and movement, or from Apple Health, Oura and Fitbit. The app took an Apple Design Award in 2023 and costs around $69.99 a year.
The daily energy timeline earns its keep for shift workers, athletes and anyone scheduling demanding work around a schedule that moves. Habit reminders arrive at the appropriate hour rather than in a morning heap. Readers who came for REM percentages, snore audio and night by night graphs will feel short changed, and there is no permanent free tier.
ShutEye pairs microphone tracking with a large audio catalogue: white noise, nature loops, bedtime stories, guided meditations and breathing exercises. It detects snoring, saves night recordings, keeps a diary and issues a morning report. The blend fits people whose main trouble is falling asleep rather than counting REM to the minute. The VIP tier costs roughly $9.99 a month or $59.99 a year, with tracking behind it.
Presentation is polished and the sound library deep, which explains the download figures. Trustpilot carries a steady stream of billing complaints about trials converting sooner than expected, so the cancellation date is worth writing down. Users have also reported changes to the stage breakdown, and readings can drift away from what a ring or watch reports the same night.
SnoreLab, a British app on the stores since 2012, does one job properly. It records the night, measures how loud the snoring gets and converts it into a Snore Score that can be compared week to week. Samples are kept as short clips, and remedies or factors such as alcohol, a nasal strip or sleeping on one side can be logged against each night to see what genuinely changes the numbers.
This is the app to open when a partner complains, because a chart and a recording carry more weight in a consultation than a description does. Premium adds unlimited recording, complete history, cloud backup and PDF export. Price rises have irritated long standing users and the free version has been trimmed. It measures sound, not sleep stages, so it works alongside a tracker rather than instead of one.
NapBot is a one developer project by Majid Jabrayilov, running since 2019, and it covers what Apple's built in Sleep screen leaves out: automatic detection of naps as well as nights, machine learning stage estimates and a history worth scrolling. It reads HealthKit data from the Apple Watch, shows sleeping heart rate and respiratory rate, and flags possible apnea patterns from breathing rate when Sleep Focus is enabled.
Widgets, complications and uncluttered charts make it a quiet daily companion, and the PRO subscription stays modest by the standards of this category. The audience is Apple Watch owners who want more than the stock view without signing up to a wellness ecosystem. Ratings run below the household names, updates arrive at an indie pace, and the apnea signal is indicative, never diagnostic.
