Features

Everything you need,
nothing you don't.

Crafted for music lovers who want their controller lightweight, beautiful, and always within reach.

Glassmorphism UI

Dark, frosted card with a subtle inner glow and pixel-perfect border highlights. Feels native to any wallpaper.

VISUAL
Real Audio EQ

Captures desktop audio via WASAPI loopback and runs a real FFT. The EQ bars react to actual frequencies — bass, mids, highs — not a fake animation.

REACTIVE
Live Spotify Sync

Track title, artist, album, and playing state — all synced with Spotify's Web API every 2 seconds over OAuth 2.0.

REAL-TIME
Drag & Drop

Click and drag the widget anywhere on your desktop. Frameless WPF window stays on top of every other app.

INTERACTION
National Font

Typography powered by the National typeface — embedded directly in the app as a WPF resource for crisp, consistent rendering at any DPI.

TYPOGRAPHY
Single .exe

Published as a self-contained C# executable via .NET's single-file build. No runtime to install, no loose files — just one binary that runs anywhere on Windows.
