1. Sleep Cycle: Tracker & Sounds

Best for: iPhone users who want sleep tracking and a smart alarm in one app.

Sleep Cycle: Tracker & Sounds tracks sleep patterns and includes sleep sounds, bringing its main tools together in one iOS app. The Smart Alarm gives it a practical use beyond reviewing sleep data. It’s a simple place to start if you want to watch your patterns and use an alarm without choosing a more specialized tracking method.

2. Sleep Cycle: Sleep Tracker

Best for: Android users seeking sleep tracking with alarm and sound features.

Sleep Cycle: Sleep Tracker tracks sleep and includes a smart alarm, sleep sounds, and snore recording. Its Google Fit integration is a useful extra for Android users who want to connect the app with that service. The Android listing differs from the iOS version in the integration it describes, so check its current details if Google Fit matters to you.

3. Pillow: Sleep Tracker App

Best for: Apple users interested in sleep-stage tracking and audio recordings.

Pillow: Sleep Tracker App analyzes sleep using an iPhone, iPad, or Apple Watch. It pairs sleep-stage analysis with audio recordings, which may suit people who want sleep estimates and recorded sounds in one app. The setup depends on which Apple device you use, so check the listing to see which option fits your routine.

4. Sleep as Android: Smart alarm

Best for: Android users who want sleep-cycle tracking alongside alarm and sound tools.

Sleep as Android: Smart alarm tracks sleep cycles and includes a smart alarm, sleep sounds, and sleep-sound recognition. That recognition feature sets it apart by adding sound tracking to the app’s alarm and audio tools. It’s a useful Android option if you want several sleep-related features in one place. Keep in mind that its estimates offer general insights, not clinical measurements.

5. SleepScore by Sleep.ai

Best for: iPhone users who prefer tracking without wearing a device.

SleepScore by Sleep.ai uses non-contact sonar to track sleep instead of relying on a wearable. It also provides sleep analysis, trends, and personalized advice. The device-free approach is its main distinction and may appeal if you don’t want to wear a watch overnight. Like other consumer sleep trackers, its results can help you observe patterns, but they aren’t a diagnosis or a substitute for professional assessment.

6. SleepWatch - Top Sleep Tracker

Best for: iPhone or Apple Watch users who want reports and sleep insights.

SleepWatch - Top Sleep Tracker tracks sleep with an iPhone or Apple Watch and includes sound recording. Its reports and insights are a draw if you want more than a basic record of your nights.

Best for: Apple Watch users who want sleep estimates based on watch data.

AutoSleep: Watch Sleep Tracker uses Apple Watch data to estimate sleep duration and show analysis and trends. Its sleep-rating feature adds a summary alongside the estimates. This is the most watch-focused app in the roundup, so it’s a better fit for people who already use an Apple Watch than for anyone looking for phone-only tracking.

8. ShutEye®: Sleep Tracker, Sound

Best for: iPhone users who want tracking alongside bedtime audio and snore tracking.

ShutEye®: Sleep Tracker, Sound combines sleep tracking with sleep sounds, bedtime stories, a smart alarm, and snore tracking.

Frequently asked questions

What does a sleep tracker measure?

Sleep tracker apps estimate sleep patterns using signals such as movement, device data, or sound. These estimates aren’t the same as a clinical sleep assessment, and results can differ between apps and tracking methods.

Do sleep tracker apps need an Apple Watch or other wearable?

No. Some apps use an iPhone or Android phone, while Pillow and AutoSleep offer Apple Watch-based tracking. SleepScore is listed as using non-contact sonar, so its stated tracking method doesn’t require a wearable.

Can a sleep tracker diagnose a sleep disorder?

No. These apps provide tracking and general insights, not a diagnosis. If you have ongoing sleep concerns, talk with a qualified health professional.

Sleep Cycle is the strongest overall pick if you want sleep-pattern tracking, a Smart Alarm, and sleep sounds in one app. It’s a practical starting point for core features without a specialized tracking setup. Sleep as Android is a solid runner-up for Android users, while Pillow is a good fit for Apple users interested in sleep-stage tracking and recordings. Choose the app that suits your device and the features you’ll use.
