Rebreeth takes your breathwork to the next level. Immerse yourself in spatial sound that naturally guides your breathing – no phone screen needed. Close your eyes, listen, and be present. How it works • Put on your headphones. • Choose a duration (2–60 min), a soundscape, and a breathing rhythm. • Let the spatial sound guide each inhale and exhale. Why spatial sound? Spatial sound is an intuitive guide. As the sound moves around you, you instinctively know when to inhale and exhale – keeping you in rhythm. Bilateral stimulation Spatial sound flows smoothly from left to right, creating an almost tangible sense of movement. This technique is inspired by EMDR therapy and focus exercises. It is believed to support mental clarity, relaxation, and emotional balance – enhancing the effects of your breathwork.

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 sounds—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 listen—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.
