Metiq: noise & ambient sounds

Metiq plays high-quality colored noise — white, pink, brown and grey — binaural beats, and relaxing ambient sounds to help you focus, study, meditate, fall asleep, or block out the world with soothing background noise. Open it, tap, listen. That's the whole app. Colored noise • White noise — the classic, masks sudden sounds. • Pink noise — softer than white, great for sleep and reading. • Brown noise — deep and warm, good for focus and tinnitus relief. • Grey noise — perceptually flat, designed to feel even across the spectrum. Ambient sounds • Sea waves, rain, fire crackling, birds chirping, café ambience, wind, crickets, and a water stream. • Start from a quick mix, or blend sounds from any category into your own mix, set each level, and save it. Binaural beats • Layer delta, theta, alpha, beta or gamma tones under any sound — headphones required. • Each band nudges a different mental state: deep sleep, meditation, relaxation, focus, alertness. Features • Four colored noises, eight ambient sounds and five binaural bands, looped seamlessly. • One mix for everything: colored noise, ambient sounds and binaural beats play together, with quick mixes to start from and your own saved mixes. • Sleep timer with quick presets and custom hours/minutes/seconds. • Pick what opens at launch: home, or straight into noise, ambient or binaurals. • Light, dark or system theme, and eight app languages. • Optional dynamic colors (Material You): the app takes its palette from your wallpaper (Android 12+). • Media-session integration: control playback from your lock screen, notification, or Bluetooth headset. • Works fully offline. Audio is bundled — no streaming, no account, no internet permission. • No ads. No tracking. No analytics. No third-party SDKs. • Tiny footprint, minimal battery use. Whether you want a sound machine to help a baby sleep, calm background noise for studying or concentration, storm and rain sounds to relax and unwind, or steady sleep sounds through the night — Metiq keeps it simple.
