Brown Noise - focus & sleep

Brown Noise is a calm, deep rumble that masks distractions, helping you drift off at night or settle into focus during the day.

Three sounds, one dial
• Deep Rumble – soft, warm sub-bass
• Natural – classic brown noise
• Soft Ocean – a slow, gentle swell
Turn the dial to switch. Sounds blend smoothly into each other, with no gaps and no clicks.

Made for the night
• Pure black screen with warm amber light – no harsh blue glow
• Sleep timers that fade out gently over the last two minutes
• Pause, resume or stop from the lock screen
• Keeps playing with the screen off
• Nightstand mode: a dim bedside clock that stays on, with burn-in protection, and lets your phone sleep again if the battery runs low

Focus sessions
A 25-minute timer for one focused block of work.

Private by design
• Works completely offline
• No account, no ads, no permission prompts
• The sound is generated on your phone and never repeats
