White, pink & brown noise + relaxing ambient sounds for sleep, study and focus.
About this app
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.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be xyz.metiq is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.6.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Metiq: noise & ambient sounds first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Metiq: noise & ambient sounds, and a listing is removed when the evidence for it stops holding up.
