SLEEP EFFECT: YOUR ARCHITECT OF CALM. Stop fighting the silence. Whether you’re battling a racing mind, a noisy neighborhood, or the hum of tinnitus, Sleep Effect empowers you to build a personalized audio sanctuary. Using a state-of-the-art layering engine, we don't just play soundsβ€”we help you conduct your environment. WHY SLEEP EFFECT? Unlike standard sound machines that play repetitive loops, Sleep Effect uses an organic replay engine. By introducing natural delays between sounds, we eliminate "loop fatigue," creating an unpredictable, immersive atmosphere that feels like the real world. THE CORE FEATURES: 1. AN INFINITE LIBRARY OF HIGH-FIDELITY AUDIO Curated by sound enthusiasts, our library is immersive and categorized for effortless discovery: * WATER & RAIN: Thunderstorms, mountain streams, and the ocean pulse. * THE GREAT OUTDOORS: Rustling leaves, meadow breezes, and forest nights. * WILDERNESS ECHOES: Haunting loon calls, distant gulls, and midnight owls. * COZY ELEMENTS: Crackling log fires and wind-swept cabins. * AIR & SPACE: Mountain gusts and soft drones to clear mental clutter. 2. THE CUSTOM MIX ARCHITECT Don’t just listenβ€”create. Layer unlimited sounds simultaneously with precision control: * INDIVIDUAL VOLUME SLIDERS: Make the rain heavy, but the distant thunder faint. * NAMED FAVORITES: Save your "Rainy Cabin" mix with custom emojis for one-tap relaxation. 3. PRECISION CONTROLS & SLEEP TIMER * GENTLE FADE-OUT: Set your timer and drift off as the audio gracefully fades to silence. * MASTER PLAYER: A polished, tactile interface to pause or stop all sounds instantly. 4. ORGANIC REPLAY DELAYS Our "Natural Replay" feature allows you to add manual delays between tracks. This ensures your environment stays fresh and organic, preventing your brain from spotting a loop. DESIGNED FOR YOUR BEDSIDE: * OBSIDIAN DARK MODE: Designed to reduce eye strain and keep your room dark. * LOCK SCREEN CONTROL: Full artwork and media controls without unlocking your phone. * BACKGROUND PLAY: Keep your soundscape running while using other apps. PERFECT FOR: * DEEP SLEEP: Mask tinnitus and silence racing thoughts. * PARENTS: Create a consistent, soothing environment for babies. * DEEP WORK: Block out office distractions and reach a flow state. * MEDITATION: Ground your practice with high-fidelity nature. Transform your space. Find your frequency. Download Sleep Effect today.

Niente is sound to fall asleep to. Rain at the window, surf, a fireplace, a Japanese zen garden. 78 soundscapes and 60 single sounds, each one recorded on its own: rain without birds, woods without a brook. Layer up to five of them, set each one where you want it, save the mix and start it again tomorrow with one tap. The timer is always on. The session fades out over the last five minutes, so quietly that you miss the ending. All night is there too, if you choose it. Eight spoken sessions take you to a place and say goodbye before the sound takes over. The voice does not come back. AirPlay sends it to a HomePod. From the Lock Screen you can pause, add 15 minutes or switch soundscapes without unlocking your phone. Niente is available as a yearly or monthly subscription. The yearly plan starts with a free week. The subscription renews automatically unless you cancel at least 24 hours before the end of the period. You can cancel any time in your Apple Account settings. If you would rather pay once, you can buy Niente for good, with Family Sharing for up to six people. If you already bought Niente, you keep everything, including what is still to come. If you downloaded Niente before version 1.3, eight sounds, the mixer, the timer and your own mixes stay free. New places are added regularly. The app needs no account. It plays in airplane mode. The spoken sessions are produced with an AI voice, from scripts written by hand. Some recordings come from the RØDE Ambisonic Sound Library (CC BY 4.0).
