Metiq
@metiq

Metiq is a free and open-source sound app for Android and beyond, built to help you focus, sleep, or tune out the world. It brings together three kinds of sound in one native app: colored noise (pink, brown, white, grey), ambient sounds (rain, sea waves, fire, wind, birds, café, crickets, stream), and binaural tones — all layerable at once, with quick and customizable mix presets for one-tap combinations.

Metiq is native on every platform it ships on, as the main goal is to keep it as lightweight and efficient as possible. It's fully open source, available on F-Droid and Google Play, with no ads, no account, and no tracking — just sound.

Donations here go directly toward developer time, app store fees, and keeping the project maintained and ad-free. If Metiq helps you focus or sleep better, consider donating something — every bit helps keep it free and independent. Thanks!
