Metiq: noise & ambient sounds

Metiq plays high-quality colored noise — white, pink, brown and grey — 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, thunderstorm with rain, fire crackling, birds chirping, café ambience, and wind.
• Start from a preset, or blend nature sounds into your own relaxing mix, set each level, and save it as a preset.

Features
• Four colored noises and six ambient sounds, looped seamlessly.
• Layer and mix ambient sounds, with quick presets and your own saved mixes.
• 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.

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.
