Past the system maximum
The dial runs to 200%. The first half drives Android's own volume; everything above it comes from a boost stage sitting on the output mix. Quick levels jump straight to 40, 80, 120, 160 or MAX.

Tuned to your ears.
One dial takes playback to 200%. From there a ten-band equalizer, deep bass and surround shape whatever app is already playing.

What's inside
A loudness stage and a full equalizer, on one screen.
Everything runs on the audio your phone is already playing — no importing, no separate player to learn.
Ten-band equalizer
Pull any band by up to 15 dB, from 31 Hz to 16 kHz, on Android 10 and up. Older releases get the five bands the platform exposes there, with the same presets behind them.
Deep bass & surround knobs
Two knobs ride their own post-EQ bands: one lifts the low end, one widens the stage. Deep Bass drops a ready-made low-end curve over the whole equalizer in a single tap.
A tuning per output
Speaker, wired and Bluetooth each remember their own boost level, preset and knob positions. Plug earbuds in and the app switches over to that tuning by itself.
Control it without opening it
A notification panel keeps less-boost, more-boost and an on/off switch in the shade, and a floating bubble can sit over any other app for the same job.
Your player, in the same place
Grant notification access and the mini player shows the current track and takes play, previous and next — so tuning and playback stop being two apps apart.
Start from a curve
Thirty-eight tone presets, then yours on top.
Pick one from the grid, nudge the bands, and save it under a name of your own. Saved presets can be renamed or removed whenever you like.
38built-in curves,
plus your own
plus your own
Every preset carries a curve for both engines, so switching phones does not change what a name sounds like. The one you choose is stored against the output you are on — a preset for earbuds, another for the speaker.

Where the bands sit
Ten bands, one chain.
On Android 10 and up the equalizer, the boost, the bass lift and the surround all live in a single DynamicsProcessing graph attached to the output mix — one chain instead of four effects fighting each other.

Android 9 and older only expose five bands — 60, 230, 910 Hz, 3.6 and 14 kHz — and the app follows the platform rather than pretending otherwise.
How hard it may push
You set the ceiling.
The boost ceiling caps the gain the dial can ask for. Pick the smallest one that gets you loud enough — the higher settings reach further, and distort sooner.

Before a level that could hurt your hearing, the app stops and says so — once for headphones, once for the speaker.
Beyond the two tabs
Reach the boost from anywhere, and watch it move.
The effects keep running in a foreground service, so the sound holds its settings after you leave the app.

Width, speed, corner radius and direction are yours to set, the ring can follow the notch and the camera hole, and it can stay hidden until music actually plays.
Private by design
An audio tool, not a data collector.
There is no server behind this app, and nothing to sign in to.
Stays on your phone
Boost, equalizer and effects all go through Android's own audio interfaces. Your levels, presets and settings live in the app's private storage — clearing its data removes them.
Nothing is recorded
The meters need the microphone to read how loud the music already is. Audio is never stored or uploaded, and refusing the permission only stops the bars from moving.
No account, ever
No sign-up, no profile, nothing to log in to. The app is free, paid for by ads — the Privacy Policy lists exactly what they collect, and the Terms of Use cover hearing and device safety.
Turn it up.
Free on Google Play, Android 8.1 and up. No account to create — open it and the dial is already there.
