About Sleep Island: Tracker & Sounds
Open Sleep Island once at night. Wake up to your sleep report. White noise, nature sounds, music, or podcasts fade out and stop when sleep is detected. Set custom timers, loop, download for offline listening, or play in the background. ◎ YOUR BEDTIME AMBIENCE Settle in with rain, wind, or crickets. Adjust multiple ambience sounds alongside podcasts or soundscapes, with separate volumes for ambience sounds and listening content. Immersive bedtime scenes unite sound and visuals. Appearance can follow the ambience or system, or stay fixed in light or dark mode. ◎ SMART SLEEP MONITORING • Auto-start: Open once during your nighttime window to begin monitoring automatically • Wearable-free: Keep iPhone nearby and sleep as usual; Apple Watch is optional • Sleep estimates: Sleep onset, final wake-up, nighttime awakenings, returning to sleep in the morning, and naps • Morning report: Duration, estimated stages, awakenings, sleep score, and multi-night trends • Energy: Night Sounds records with less energy. With it off, tracking needs no all-night app activity; when the app is not running, it does no continuous overnight work With Health permission, sync Apple Watch sleep records. With the Watch app connected to iPhone, view last night's summary, start/stop monitoring, play/pause, or skip back/forward. iPhone tracks sleep independently. ◎ NIGHT SOUNDS—MORE THAN SNORING Detected clips can include: • Snoring, heavy breathing, coughing, sleep talking, and possible teeth grinding • Baby cries, babbling, and other vocal sounds • A partner's voice and sounds from the room • Full recorded clips and playback history; 15 seconds limits only some free previews, not recording length • “Not Me” for sounds from someone else • Play, pause, resume, favorite, batch delete, or mark multiple clips “Not Me” Full playback beyond free previews and Favorites require Premium. Baby and other Night Sounds are for review and memories, not medical use or baby safety monitoring. ◎ A CLEAR BEDTIME SCREEN The sleep card and playback controls stay separate. Start or check monitoring at a glance, access sounds, music, and podcasts, and control playback. ◎ SOUNDS, AUDIO & VIDEO • Six colors of noise: White, pink, brown, blue, green, and purple • Nature: Rain, ocean waves, streams, forest, crickets, campfire, fireplace, wind, and hundreds more • Music: Piano, ambient, classical, Lo-fi, meditation, binaural beats, 432Hz, 528Hz, and more • ASMR: Tapping, page turning, makeup sounds, and other gentle triggers • Audio: Bedtime stories, audiobooks, and English learning • Immersive video: Forests, rain, valleys, streams, blizzards, and dreamscapes with panoramic panning • Sound mixing: Blend your own soundscape ◎ BEDTIME PODCASTS • Search Apple Podcasts and add RSS feeds • Curated bedtime stories, meditation, white noise, ASMR, English listening, talk shows, and regional charts • Resume automatically from where you stopped • Smart sorting for series and standalone episodes ◎ AMBIENT SCENES, RELAXATION & FOCUS • Open the app to an atmosphere of sound and visuals • Switch among cicada summer nights, rain by the window, morning birdsong, and more; set a custom duration • Unwind with box breathing or 4-7-8 breathing • Use Focus mode for work, study, and reading ◎ AI SLEEP ANALYSIS AI sleep analysis compares multiple nights with your personal baseline, using scores, estimated stages, awakenings, and Night Sounds summaries for personalized analysis and suggestions. View weekly and monthly trends. ◎ MENTAL WELLNESS CHECKS PHQ-9, DBAS-16, and other established questionnaires support self-reflection; they do not replace professional diagnosis. ◎ MUSIC ALARM (iOS 26+) Wake to music that gently fades in. Set multiple alarms, smart public-holiday or alternating-week schedules, and labels for wake-up, naps, medication, going out, pickups, workouts, and more.

What’s new
Version 1.8.1 · Updated September 30, 2026
Ambient scenes on Home are now ordered by listening time, and their names appear as a small caption below the artwork. The podcast row on Home now shows more shows. My Sleep now has “Chat with the developer” at the bottom, with a red dot when there's a new reply. Fixed “Report is not ready yet” occasionally staying on screen after you end monitoring. Fixed the app occasionally being closed by the system when you return to it while the phone is busy, and Night Sounds for some nights never finishing processing.
