The picks, in order

  1. 1AutoSleep app icon

    AutoSleep

    $9.99 onceOur pick4.7

    Pick it if you wear your Apple Watch overnight and want detailed sleep stats for 1 price.

    If you wear your Apple Watch to bed, AutoSleep tracks the night without you pressing anything, and it still logs your time in bed on nights the Watch stays on the charger. Each morning you get a sleep rating and rings for deep sleep, REM and heart rate, plus blood oxygen, breathing rate and wrist temperature. It costs $9.99 once and collects no data, where Athlytic charges $29.99 a year for its sleep scores.

  2. 2Bevel app icon

    Bevel

    Free to startBest free4.8

    Pick this if you want free sleep and recovery scores, and you wear an Oura ring or an Apple Watch.

    Get recovery, sleep, strain and stress scores from the Apple Watch, Oura or Garmin you already wear, without buying a Whoop band. Those scores, the strength log with over 700 exercises and food logging are all free since version 2.4.0 in December 2025. Pro, at $14.99 a month or $99.99 a year, adds the Bevel Intelligence AI coach, health records, biological age and training plans.

  3. 3Athlytic app icon

    Athlytic

    From $4.994.8

    Pick it if you care how last night's sleep affects today's training more than the sleep stages themselves.

    Apple's Health app records your overnight heart rate variability and resting heart rate, then leaves you to work out what they mean. Athlytic turns them into a recovery score each morning and a target for how hard to train, scores your sleep and sends structured workouts to your watch, all processed on your iPhone with no account. There is no free tier: after the 7-day trial it costs $4.99 a month or $29.99 a year.

  4. 4Dark Noise app icon

    Dark Noise

    Free to start4.8

    Pick this if you fall asleep to rain, fans or brown noise and want to mix and time the sounds.

    All 50+ sounds live on your device, so this noise app keeps playing on a plane or in a hotel with bad Wi-Fi. Blend green, brown, pink and white noise into your own mixes, fade out on a timer, or start one from a Lock Screen widget or Siri, even on HomePod. The free set is small, and Pro at $19.99 a year or $49.99 once costs less than Endel's Premium.

  5. 5Endel app icon

    Endel

    Free to start4.6

    Pick it if you want sleep sounds that adapt on their own instead of a fixed noise loop.

    Put on sound that shifts with the time of day, the weather and, with an Apple Watch, your heart rate, so you get background audio without lyrics or a playlist that runs out. The free edition keeps the classic Focus, Sleep, Relax and Move soundscapes, and they play offline. Premium adds colored noise and a focus timer, but Dark Noise is cheaper at $19.99 a year if steady noise is all you want.
