Sleep isn't a luxury. It's a performance tool. Monotone is the sleep audio app for adults who are done counting sheep. Narrated sleep stories, immersive soundscapes, and guided wind-downs — all engineered to get you out of your head and into deep, restorative sleep. Our sleep stories for adults aren't bedtime fluff. They're precisely crafted narratives — slow-paced, richly descriptive, and deliberately boring in the best way — designed to quiet an overactive mind and carry you to sleep before the story ends. Built for adults. Designed for real life. Stressful day? Racing thoughts? Can't switch off? Monotone is built for exactly that moment. Premium audio content that meets you where you are and guides you somewhere better. Sleep Stories for Adults - Long-form, narrated stories crafted to dissolve tension and slow your thoughts. New stories added every week. Soundscapes & Atmospheres - Layered, high-fidelity audio environments. Rain on glass. Deep forest. Slow static. Find your frequency. Sleep Meditations - Short and long-form meditations built specifically for sleep — not morning motivation, not focus. Just rest. What's inside: Sleep Stories — Literary · Nature Journeys · Mystery · Travel · History · Slow Fiction · Non-Fiction Soundscapes — White noise · Brown noise · Rain · Ocean · ASMR · Ambient · Lo-fi Wind-Downs & Meditations — Body scan · Breathwork · Progressive relaxation · Anxiety relief · Deep sleep · Napping Monotone is for the adult who's tried everything.
