About this app

Fall asleep faster, stay asleep longer.

RelaxFX is a sleep and relaxation sound app with a difference: every scene is built from multiple independent audio layers, each looping at a different prime-number length. The result: audio that effectively never repeats — no jarring loop points to pull you out of sleep.

16 IMMERSIVE SCENES

🌧 Rain — 4 layers: steady rainfall, drops on metal roof, puddle splashes, distant thunder
🌩 Heavy Storm — driving rain, howling wind, low rumbling thunder
🔥 Campfire — crackle, low roar, occasional wood pops
🌲 Forest — wind through leaves, crickets, songbirds, distant owls
💧 Stream — flowing water with splashing rocks
🌊 Ocean — rolling waves, beach wash, distant calm sea
🐳 Underwater — muffled deep
💨 Howling Wind — winter winds with gusts
🟫 Brown Noise — deep steady hiss
🟨 Pink Noise — balanced spectrum for deeper sleep
⬜ White Noise — flat spectrum
☕ Coffee Shop — busy cafe ambience
🚆 Train — rolling rumble for travel-style sleep
🌬 Fan / Heater — steady mechanical hum
❤️ Heartbeat — slow steady pulse
🎶 Singing Bowls — tonal Tibetan drones
