Nine sounds, a proper sleep timer, and nothing else competing for your attention.

FIVE CLASSIC NOISES — ALWAYS FREE
• White noise — a steady, even hush
• Pink noise — softer and warmer than white noise
• Green noise — the midrange of the natural world
• Brown noise — deep and rolling, like distant surf
• Deep Brown noise — lower still, felt more than heard

NATURE SOUNDS PACK — ONE-TIME UNLOCK
• Birdsong — a bright morning canopy
• Crackling Fire — slow embers in a quiet grate
• Tibetan Singing Bowls — long bronze tones, fading
• Wind Chimes — loose notes on a slow breeze

Tap any locked sound to hear thirty seconds of it before you decide. One purchase unlocks all four forever — no subscription.

A SLEEP TIMER THAT ACTUALLY SLEEPS
Set 15 minutes, 30 minutes, an hour, any custom duration, or a wake-up time. Slumbertone fades out gently when the timer ends, or stops instantly if you prefer. It keeps playing in the background, so you can lock the screen and put the phone down.

WHY COLOR NOISE HELPS
Consistent background noise masks distractions and smooths out the sounds around you — traffic, a snoring partner, a noisy hallway, an open-plan office. Brown noise and white noise are the usual starting points for sleep; green noise and pink noise are gentler if white noise feels harsh. Many people use ambient sound for deep work, study sessions, reading, meditation, or settling down at bedtime.

BUILT FOR THE DARK
Every sound is a two-minute studio loop that repeats with no click and no gap, so nothing catches your ear at 3am. Switching sounds crossfades instead of cutting. The background breathes slowly in the color of whatever is playing, and the whole app is dark by design.

• Plays in the background, with full media controls
• Phone and tablet layouts
• Works offline once installed
• No accounts, no ads, no tracking, no data collected

HOW TO USE IT
Pick a sound, press Play, set a timer. That is the whole app.

Headphones or a bedside speaker recommended.
