Read full descriptionHide full description
Every sound is generated in real time. No loops, no audio files, no seams. Pay once and keep it forever. No subscription, no account, no ads. Liquid Noise makes six sounds and does them properly: β£ White Noise β Equal energy across every frequency, the classic masker for sudden sounds β£ Pink Noise β Softer in the highs, like steady rain β£ Brown Noise β Deep and rumbling, the one people reach for to sleep and to focus β£ Green Noise β Mid-range and natural, like rushing water β£ Blue Noise β Bright and crisp for covering high-pitched hums and whines β£ Ocean Wave β Rolling surf with natural wave cycles What you get: β£ Siri and Shortcuts β "Play brown noise with Liquid Noise", "Stop Liquid Noise", "Set a Liquid Noise sleep timer" β£ Sleep timer with fade-out β 20, 45 or 90 minutes, 4 hours, all night, a 30-minute gradual fade, or your own length β£ Home Screen widget β start or stop a sound without opening the app β£ Control Center button β start your chosen sound from anywhere (iOS 18 and later) β£ Live Activity β the sleep timer counts down on the Lock Screen and in the Dynamic Island, with a Stop button right there β£ Sleep Focus β set your preferred sound and timer to be ready when Sleep Focus turns on β£ Background playback with lock-screen controls β£ Works completely offline β nothing to download, nothing to stream β£ No accounts, no tracking, no analytics β your sleep is your business β£ VoiceOver support throughout β£ Dark interface that stays easy on your eyes at bedtime β£ 7-day free trial, then a single one-time purchase Perfect for: β’ Falling asleep faster with steady, consistent background sound β’ Focus during work or study β’ Masking tinnitus β’ Helping babies and children settle β’ Blocking neighbors, traffic, or roommates β’ The same sleep environment every night, anywhere How it works: 1. Open the app 2. Tap a sound β it starts immediately 3. Set the volume and a timer if you want one 4. Lock your phone and sleep Because the sound is synthesized on your device rather than played from a recording, there is no loop point to notice and no library of audio files taking up space. It runs all night on a small amount of battery. Try it free for 7 days. If it helps you sleep, pay once and keep it forever.
