Metiq plays high-quality colored noise to help you focus, fall asleep, or block out the world. Pick a color, tap, listen. That's the whole app. • Pink noise — softer than white, great for sleep and reading. • Brown noise — deep and warm, good for focus and tinnitus relief. • White noise — classic, masks sudden sounds. • Grey noise — perceptually flat, designed to feel even across the spectrum. Features • Four colored noises, looped seamlessly. • Sleep timer with quick presets and custom hours/minutes/seconds. • 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. Open source under GPL v3.
