NightEcho: AI Sleep Tracker

See stages, score, snoring and sleep-talking clips. When available for your language and region on a compatible iPhone, Apple Intelligence works on device and offline.

Wake up knowing what happened while you slept. NightEcho is a private sleep tracker, sleep recorder, and AI sleep coach for iPhone. See estimated sleep stages and score, replay snoring and sleep-talking clips, explore trends, and turn every report into a personalized plan.

TRACK SLEEP FROM YOUR BEDSIDE

Start a session before bed and let NightEcho monitor nighttime sound and movement patterns. Explore estimated Awake, REM, Light, and Deep sleep stages, duration, consistency, and a nightly score. No wearable is required for iPhone tracking.

RECORD SNORING, SLEEP TALKING & MORE

Hear key moments in clips of about 10 seconds. NightEcho detects:

• Snoring
• Sleep talking
• Teeth grinding
• Coughing
• Other bedroom noise

Replay clips from your report and clear recordings by category. NightEcho does not save one continuous all-night recording.

AI INSIGHTS, POWERED BY APPLE INTELLIGENCE

On a compatible iPhone, when Apple Intelligence is turned on and available for your language and region, NightEcho uses Apple's on-device Foundation Models to explain report patterns, answer questions, and create a plan for tonight. Your sleep summary and prompts are processed on your iPhone, and AI can work offline.

If the on-device model is unavailable, NightEcho can offer cloud AI only after your separate consent. Cloud requests send only the text you enter and the structured sleep summary needed for a response. Raw sleep recordings and event clips are never sent to cloud AI.

FOLLOW YOUR SLEEP TRENDS

Review nightly reports and 7-day or 30-day trends for score, duration, stages, bedtime consistency, time to fall asleep, awakenings, snoring, naps, and more.

FALL ASLEEP WITH SOUND

Choose sleep sounds, nature audio, and music, or mix up to five sound layers. Adjust each volume, set a timer, and use fade-in or fade-out. Mix white, brown, or pink noise with rain, ocean, fan, and more.

WAKE UP AT A BETTER MOMENT

During an active tracking session, Smart Alarm can wake you earlier when NightEcho estimates light sleep or awake time within your wake-up window. Use Nap Timer for a shorter daytime rest.

ADD APPLE WATCH SLEEP INSIGHTS

With permission, NightEcho reads compatible Apple Watch data from Apple Health, including sleep stages, heart rate, HRV, respiratory rate, blood oxygen, wrist temperature, and breathing disturbances. Availability depends on your device, permissions, and recorded samples. NightEcho does not write to Apple Health.
