Booster pushes your volume past the system limit with clean, distortion-controlled gain — a limiter guards the end of the chain, so louder never means crackle.

Most boosters crank one slider and let it distort. Booster splits the job the way hardware does: gain, limiter, and a real equalizer — each doing only its part.
Clean gain beyond 100% on speakers, wired headphones and Bluetooth. A built-in limiter sits at the end of the chain and catches peaks before they clip.
Ten bands with Bass, Surround and Reverb — fully independent of the boost. Works at any volume, even with the booster switched off.
Start the boost, switch to Spotify or YouTube — it stays active, with controls in a persistent notification.
An optional mini player detects what's playing and gives you play, pause and skip without leaving Booster.
Fall asleep to your music — Booster switches the boost off by itself when the timer runs out.
Clear warnings at high boost levels — because louder should always be your choice, not an accident.
Booster's one hard rule: with the boost and EQ turned off, it applies zero processing. No hidden "enhancement", no silent EQ curve.
Everything off → bit-for-bit system sound. The effects join the chain only when you raise the dial past 100% or switch the equalizer on — and leave it the moment you turn them off.
Booster collects nothing — no analytics, no ads, no personal data. Your settings live only on your phone, and every bit of audio processing happens on the device itself.
