Hear what happens while you sleep.
Ever wondered what happens while you’re sleeping? Do you snore, cough, talk in your sleep, or make other unexpected sounds?
Night Time Noise helps you discover, understand, and track the sounds of your nights — all from your iPhone or iPad.
Simply start a recording session before bed, place your device nearby, and go to sleep. Night Time Noise detects significant sounds and saves short recordings for you to explore the next morning.
No complicated equipment. No subscriptions. Just a fascinating look at what happens while you sleep.
DISCOVER YOUR NIGHT
Night Time Noise automatically detects significant sounds while you sleep, capturing short audio clips rather than recording hours of silence.
In the morning, listen to individual recordings and discover sounds you never knew you were making.
SEVEN SOUND CATEGORIES
Classify recordings using seven categories:
• Snore
• Cough
• Voice
• Yawn
• Breathing
• Other Noise
• Unsure
Whether you’re curious about snoring, sleep talking, or ordinary nighttime sounds, Night Time Noise helps you build a clearer picture of your sleeping environment.
SMART SNORE DETECTION
Our developing sound-recognition technology analyzes recordings and identifies sounds that may be snoring.
These intelligent suggestions help you focus your review while leaving you in control of the final classification.
