Serenity: Sleep Sounds & ASMR

Tired of sleep apps that force you through 20-minute breathing lectures? Serenity isn't another meditation library. It's a precision audio tool built to help you fall asleep fast, hit flow state at work, or calm anxiety in minutes. No voices. No interruptions. Just pure, functional sound. WHY SERENITY IS DIFFERENT Unlike YouTube or Spotify – which compress audio and break ASMR triggers – Serenity delivers studio-grade sound (up to AAC 320 kbps) with seamless crossfade looping. No micro-pauses. No jarring ads. It just works. Every sound in the library is a real recording or a research-grade generator. No AI-generated audio. WHAT YOU CAN DO Sleep — Mix rain, ocean waves, and gentle wind to fall asleep in 15 minutes. The smart timer fades out when you drift off. Focus — Brown Noise + 40Hz Gamma binaural beats: the combination ADHD communities swear by. Lock into 90-minute deep work blocks. ASMR — High-quality triggers (tapping, scratching, page-turning, brushing) without draining your battery on video. Calm — 2-5 minute sessions designed to lower heart rate between stressful meetings. Nature sounds backed by cortisol-reduction research. 120+ SOUNDS ACROSS 4 CATEGORIES Sleep: rain variations, ocean, thunder, campfire, wind, jungle, heartbeat, distant birds Calm: forest creek, birdsong, singing bowls, waterfall, cave ambience, underwater, wind chimes, kalimba, meditation piano Focus: brown/white/pink noise, binaural beats (delta to gamma), coffee shop, library, deep drone, pad drone ASMR: tapping, scratching, keyboard, brushing, paper, fabric, water drops, slime, scissors Plus free seasonal collections throughout the year.
