Evermur: Sleep & Rain Sounds

Evermur is a sleep sounds and white noise app for sleep, focus and calm — built on one simple idea: the sound should never repeat. No short loops, no obvious seams, no pattern your mind can latch onto. Just long, continuous, real nature recordings that keep flowing, so it feels like being there.

Perfect for falling asleep, relaxing, studying, meditation, or blocking out noise.

SIX LIVING SOUNDSCAPES
• Rain sounds — from a soft drizzle to a full thunderstorm, with distant thunder that grows as you turn it up
• Ocean & sea waves — a slow, calming wash that never loops
• Fire — a warm, crackling fireplace / campfire with its natural low hum
• Night — a calm summer night of crickets and frogs
• Forest — a living forest full of birdsong
• Wasps — a gentle, hypnotic summer buzz

Every soundscape is stitched from real field recordings and recombined so it never repeats — closer to natural white noise or brown noise than a looping track, and gentler on the ears over a long night.

ONE DIAL FOR INTENSITY
Every scene has a single slider — from barely-there to fully immersive. Rain even brings in thunder as the storm builds, growing not louder but more frequent.

SLEEP TIMER
Set a sleep timer for 15, 30, 60 minutes or leave it endless. The sound fades out gently and you can adjust it right from the media notification.

BRAINWAVES — BINAURAL BEATS (HEADPHONES)
An optional binaural-beat layer based on a science-informed frequency table — Deep Sleep, Sleep, Trance, Meditate, Relax, Light Rest, Focus and Peak (delta, theta, alpha and beta). Each is a pure two-tone pair tuned to a target brain-state rhythm, kept quiet and in the background. Use headphones. (Not a medical device; for relaxation only.)

MADE FOR SLEEP AND FOCUS
• Sleep timer — 15, 30, 60 minutes, or endless
• Background playback with lock-screen and notification controls
• A deep, dark, OLED-friendly design — no bright screens at night
• A calm, breathing play orb, with almost no text you don't need
• Great for sleep, naps, relaxation, focus and study, meditation, yoga, tinnitus relief, and soothing a restless mind

PRIVATE BY DESIGN
No account. No sign-up. All the sound plays on your device. Nothing interrupts you: there are no banners and no ads between screens. The only ad in Evermur is a single video on the About screen that you can choose to watch if you'd like to support the work — the soundscape pauses for it and fades back in afterwards, and if you never press it, no ad is ever loaded. Analytics is anonymous and aggregated (Google Firebase, for crash reports and usage) — never linked to you, never sold.
