Moss: Green Noise & Sleep
Brown, white & pink noise
Only for iPhone
Free · In‑App Purchases
iPhone
Green noise, generated live on your phone. Even, seamless, and gentle.
Moss generates green noise the way instruments make sound — synthesized live on your iPhone, never a looped recording. No seams, no repeats, no downloads: an infinite, perfectly even field of sound for sleeping, studying, and settling a busy mind.
One quiet screen. Press the orb and drift.
FREE, FOREVER
• Canopy — classic green noise, tuned to the gentle mid-frequencies sleepers love
• Sleep timer with a slow fade-out that won't wake you
• Plays in the background, on the lock screen, and in the Dynamic Island
• Featherlight on battery — engineered to sip power through the night, and quiets its own animations in Low Power Mode
• 60-second previews of every premium sound
• No account. No ads. No tracking. Analytics is anonymous and optional.
MOSS+ (subscription)
• Three more synthesized textures: Riverbed (deep brown noise), Rainfall (bright pink noise), and Mist (soft white noise)

• Home and Lock Screen widgets: your sound and sleep timer at a glance
• Six app icon colorways
Works with Siri and Shortcuts ("Start Moss sleep timer") for bedtime automations.

Cleaner sound, and a friendlier free trial.
• Sharper, cleaner high frequencies — noticeable on the brighter tone settings, and on Rainfall especially.
• Free trials now include a heads-up before they end, so you're never surprised by a charge.
• Steadier playback around phone calls, alarms, and car audio.
• Small fixes and refinements throughout.
