Sound, Supercharged.

A studio-grade 10-band equalizer, bass booster and volume boost for the music you own — wrapped in a neon cockpit built for iPhone, iPad and Mac.

Download on the App Store Free to use — one Premium subscription unlocks everything on iPhone, iPad and Mac.

10-Band Equalizer

Precision faders from 32 Hz to 16 kHz with a live response curve, real-time analyzer and 30 genre presets.

Bass Boost & Volume

Deep low-end boost and up to 2× volume — with an always-on limiter so loud never means distorted.

Studio Effects

Pitch shift, playback speed and spatial widening, each with its own instrument-grade control.

Per-Device Presets

Your AirPods, car and speaker each get their own sound — applied automatically the moment they connect.

Hearing Tune

A guided listening test builds a personal EQ curve matched to how you actually hear.

Private by Design

No accounts. Your music never leaves your device. The free iPhone and iPad version is ad-supported; Premium removes ads entirely, and the Mac version has none.

Honest About DRM

Effects apply to DRM-free music — songs you import and DRM-free tracks in your library. DRM-protected streaming songs can't be processed by any app on iPhone, iPad or Mac, and we say so up front instead of after you pay.
