Liquid Noise - Sleep Sounds

Pay once, sleep forever. No subscriptions. No accounts. No nonsense.

Liquid Noise is the only white noise app you'll ever need. Just six scientifically-proven sounds, a volume slider, and a timer. That's it.

What You Get:
• White Noise – Equal energy across all frequencies for masking sudden sounds
• Pink Noise – Balanced frequency distribution that sounds like gentle rain
• Brown Noise – Deep, rumbling tones for profound relaxation
• Green Noise – Natural mid-range frequencies like rushing water or ocean waves
• Blue Noise – Bright, crisp high frequencies for masking tinnitus and electronic hums
• Ocean Wave – Rhythmic surf sounds with natural wave cycles for deep relaxation

• One-time purchase of $2.99 – use forever, no recurring fees
• 7-day free trial – full access, no credit card required
• Sleep timer with fade-out – set 15 minutes to 8 hours or play all night
• Background playback – continues when your phone is locked
• Works completely offline – no internet required after download
• No accounts required – your privacy is protected
• No ads – clean, distraction-free experience
• Dark interface – easy on your eyes at bedtime

Why We're Different:

Unlike subscription sleep apps that charge $60-80 per year, Simple Sleep Sounds is a one-time purchase that works forever. We believe you shouldn't have to pay monthly for something as simple as white noise.

NO SUBSCRIPTION – Pay $2.99 once, use forever
NO COMPLEXITY – Just 6 sounds and a timer, not 300 features you'll never use
NO DATA COLLECTION – Your sleep is your business. We don't track you.
NO ADS – Clean, distraction-free experience designed for sleep
NO ACCOUNTS – Download, open, and sleep. That's it.
