## What is Flux?

Shift gears for your mind. Flux is a minimalist audio tool designed to silence the noise of the modern world and instantly put you into a "Flow" state.

No complex settings, unnecessary graphics, or distracting statistics. Just scientifically engineered sound frequencies for deep focus, peaceful sleep, or a productive coding session.

WHY FLUX?
Modern apps compete to steal your attention. Flux gives it back to you. Built with an "Invisible Design" philosophy, the interface serves your purpose and then gets out of the way.

MODES:
• FOCUS: Brown Noise and deep frequencies to sharpen your attention to a laser point.
• SLEEP: Slow down your mind with 432Hz and ethereal space atmospheres for deep rest.
• CODE (Flow): Cyber-acoustic rhythms designed for developers and creators—engaging but never fatiguing.
• ZEN (Breathe): Escape anxiety and breathe with the purest sounds of nature.

FEATURES:
• Radical Simplicity: Start with a single tap.
• Living Interface: A visual atmosphere that breathes in sync with the rhythm.
• Background Play: Focus continues even when your phone is locked.
• Offline Mode: No internet connection required.
• AirPlay Support: Turn your room into a sanctuary of focus.
