Hush Hour: White Noise & Sleep

Hush Hour is a white noise and sleep sounds app built on three principles: privacy first, then reliability, then simplicity. Mix real recordings of rain, sea, stream, forest, wind, crickets and fire, add white, pink or brown noise, and drift off.

Use it to mask a noisy street or a snoring partner, to fall asleep, to rest, or as steady sound while you read or work.

★ PRIVATE BY DESIGN
• Works fully offline. The app does not even ask for internet access
• No ads, no account, no tracking
• Your mixes and settings stay in Hush Hour's own storage on your phone

★ RELIABLE THROUGH THE NIGHT
• Keeps playing with the screen off, with controls on the lock screen
• Pauses for calls and comes back after, and pauses when headphones come out
• Every bed is steady: sudden jumps in sound are what wake you
• Starts quiet, with a soft ceiling on loudness you can turn off

★ SIMPLE: PAY ONCE, PRESS PLAY
• Pay once. Every sound and every feature, no subscription
• One tap dims the screen to black with only the time
• A home screen widget to play or pause in one tap
• Light, dark and true black looks, or follow the phone, with TalkBack labels and large text support
• In English, German, Spanish, French, Hindi, Indonesian, Japanese, Korean, Portuguese, Russian and Turkish

★ REAL SOUNDS, NOT SYNTH
• Rain: on a yard, on the window glass, on the roof, on a tent, a mountain downpour, and a storm with far thunder
• Water: ocean waves on the shore and a river stream
• Woods and night: birds in the forest, wind in the leaves, crickets on a summer night
• Fire: a campfire under the stars and a fireplace indoors
• Noise: a bedroom fan, and white, pink and brown noise
Every nature sound is a field recording, cut into long loops of two to four minutes that join without a seam. Each one starts at a new point and drifts a little in level, so you never learn the loop.

★ MIX YOUR OWN
• Play up to eight sounds at once, each with its own slider
• Save your mixes, or start from nine ready made ones: Rainy cabin, Summer night, Storm at sea, Deep focus and more

★ A CALM, CLEAR SCREEN
The sleep timer is a watch dial: one soft arc shows the time left and the clock time it goes silent. One moonlight colour marks only what is playing, on a calm ground with big, easy type. No busy pictures to keep you awake.

★ BUILT FOR SLEEP
• A sleep timer from 15 minutes to 2 hours 30, or all night
• A slow fade out at the end, over 5, 10 or 20 minutes
• Rare moments like thunder or an owl stay soft, and you can turn them off

★ WHY IT FADES
In a review of 38 studies, steady noise tended to help people fall asleep, though the evidence is still weak (Riedy and colleagues, Sleep Medicine Reviews, 2021). Sudden jumps in sound are what wake you, so every bed in Hush Hour is steady (Stanchina and colleagues, Sleep Medicine, 2005). A 2026 sleep lab study found pink noise played all night cut dream sleep (Basner and colleagues, Sleep), so the timer fades out after you drift off by default. All night is still one tap away.

Hush Hour is for rest and relaxation. Hush Hour is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. For sleep problems, talk to a doctor or other healthcare professional. With a baby, keep the phone across the room and the level low.
