A compact all-purpose loudness tool with the same vintage panel language.
Music Equalizer
Five-band EQ and custom presets — make the phone sound like a small HiFi.
Built like a small studio
Interfaces that look like gear, algorithms that treat volume as more than a slider.
Hands on the mix
Potentiometers, bass sliders, mute / normal / boost, and 5-band EQ — tactile, not buried in menus.
Stay in the session
Toggle boost from the notification, launch your player from the app, and keep going on Wear OS.
Headphones first
The apps are honest: plug in speakers or headsets when you want the full effect.
Free, with ads
Every title is free to install. Ads keep the studio running; privacy controls live in the app.
