Sleep Tracker Apps in 2026: 7 Options and Their Limits

Start with your device and your purpose. Sleep Cycle and Sleep as Android offer phone-based tools, AutoSleep is built around Apple Watch, and Pillow combines Apple-device tracking modes. BetterSleep and ShutEye include bedtime audio. HabitBox records a routine, not sleep stages.

How this comparison was researched

Updated 8 October 2026. We reviewed the official developer or store sources linked below and inspected their published screenshots. This is a researched comparison, not a hands-on test or a measurement of health outcomes. We do not assign star ratings. Screenshots come from the developers’ official pages and may include promotional text; those claims are not our findings.

HabitBox is our own product. Where it appears, we explain its limited role alongside dedicated apps.

Compare the options

The listing column identifies the source reviewed, not an exhaustive platform list. A free download does not mean all features are free. Plans, device support and regional prices can change; check the linked listing and purchase screen before subscribing.

Sleep Cycle — Phone-based sleep estimates and an alarm

Sleep Cycle describes sound or movement-based sleep tracking, a smart alarm window, nighttime sound detection and trend views. It also includes sleep notes and audio content. It is a shortlist option if you want to try recording nights without buying a wearable. Official listing.

Check before choosing: Phone-based sleep stages and scores are estimates. Roommates, pets and the position of your phone can complicate interpreting sound recordings; check microphone and storage settings.

Sleep as Android — Android alarm and sleep tools

Sleep as Android combines an alarm with sleep tracking and a set of bedtime and wake-up tools. Its current Play listing is the right place to check supported wearable integrations and the options available on your particular phone. Official listing.

Check before choosing: Check battery, background operation and hardware requirements before depending on an overnight recording or alarm.

AutoSleep — An Apple Watch sleep record

AutoSleep uses Apple Watch data to present sleep duration, trends and other overnight measures. Its listing also describes integration with Apple’s own sleep-stage data. The app is a paid download and explicitly states that it has no extra in-app purchases or subscription. Official listing.

Check before choosing: It is built around Apple Watch use. A sleep score or stage graph cannot diagnose a sleep disorder, regardless of the language used in store marketing.

Pillow — Sleep summaries in the Apple ecosystem

Pillow offers automatic Apple Watch tracking and a manual mode, along with sleep reports, heart-rate analysis and audio recording features. It also presents trends alongside information from Apple Health. Official listing.

Check before choosing: The available recording and analysis features depend on the mode, device and plan. Sleep-stage labels and audio classifications should be treated as estimates.

BetterSleep — Sleep audio with tracking features

BetterSleep combines soundscapes, stories and guided audio with a sleep tracker and recorder. Its focus on audio makes it worth comparing if your main goal is selecting something to listen to at bedtime rather than studying a detailed wearable dashboard. Official listing.

Check before choosing: A large audio catalog does not establish that an app will improve a particular sleep problem. Check subscription access and audio recording permissions.

ShutEye — Sleep reports plus bedtime audio

ShutEye bundles a sleep tracker, nighttime sound recording, a smart alarm and a library of sounds and bedtime stories. Its developer also lists customizable sound mixes. Official listing.

Check before choosing: Choose it for the workflow and content you want. A consumer app cannot confirm sleep apnea or explain persistent fatigue from an overnight recording.

HabitBox — Recording a bedtime routine

HabitBox can record a chosen bedtime action, such as preparing for bed at a planned time or completing a short wind-down routine. Its reminders and history concern the action you record, rather than measuring what happens while you sleep. Official listing.

Check before choosing: HabitBox is our own product. It does not detect sleep stages, record nighttime sounds or diagnose sleep problems.

A sleep score is an estimate

Consumer apps infer sleep from signals such as movement, sound or wearable data. A detailed chart is not the same as a clinical sleep study. We have not compared these apps against a laboratory reference, so this article does not rank their measurement accuracy.

Before paying, check how a recording starts, whether the phone must be charging, which permissions it uses and how recordings are stored or deleted. For a watch-based app, confirm compatibility with the watch and operating system you own.

Which kind of app fits your goal?

If you want to review a bedtime routine, a simple diary may be enough. If you want audio at bedtime, compare the audio catalog and subscription access. If you want overnight trends, compare the reports and export options, while accepting that the numbers are estimates.

Persistent sleep problems, breathing concerns or excessive daytime sleepiness warrant a conversation with a healthcare professional. Do not use a reassuring app score to rule out a problem.
