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.
Perfect For:
• Falling asleep faster with consistent background noise
• Masking tinnitus with scientifically-proven sound frequencies
• Helping babies and children sleep with calming white noise
• Blocking neighbor noise, traffic, or roommate sounds
• Improving focus during work or study sessions
• Creating a consistent sleep environment every night
• Masking high-pitched disturbances with blue noise
• Enjoying nature-inspired sounds without large audio files
How It Works:
1. Download and open the app
2. Tap a sound to start playing immediately
3. Adjust volume and set a timer if desired
4. Lock your phone and sleep
The app generates high-quality noise algorithmically in real-time, so you get crystal-clear audio without the large file sizes. All sounds loop seamlessly with no gaps or interruptions.
Our Philosophy:
We built this app because we were tired of subscription apps that charge monthly for features we never use. Liquid Noise does one thing perfectly: helps you sleep better with scientifically-proven noise generation. No meditation content. No celebrity voices. No social features. Just pure, simple, effective sleep sounds.
Try it free for 7 days. If it helps you sleep, pay $2.99 once and use it forever. If not, delete it. Simple as that.
Built by people who hate subscriptions, for people who need sleep.
