★ PRIVACY FIRST ★

Flux does not record or upload your audio. All processing happens on your device. We don't ask for personal information, and we never sell your data. See our privacy policy for details.

★ PERMISSIONS ★

Flux needs access to audio output APIs so it can apply enhancements. It does not record audio, listen to your microphone, or monitor what you play.

★ NOTE ★

Audio effects depend on your device's hardware and the app playing audio. Some apps or devices may restrict third-party audio effects. If Flux isn't working with a particular app, try enabling it from your music app's settings or check our troubleshooting guide.

What’s new

We got tired of equalizers that bury the good stuff behind a paywall and drown you in ads. So we built the one we wanted to use.
Flux is a full 10-to-31-band EQ, bass booster, and volume booster — system-wide, no ads, no subscription.
It's finally here. Thank you for trying it. This is just v1.0.
