Turn your Divoom Pixoo 64 into a living now-playing display. PixelFlow streams album art, animated clocks, and local weather straight to the 64×64 LED panel over Wi-Fi — no account, no clutter, just your music on the wall. Set it on your desk or shelf and let it show whatever you're listening to, in real time. NOW PLAYING • See the cover of whatever's playing in Apple Music, scaled beautifully to the panel. • Not on your phone? Let Shazam listen and identify music in the room — Spotify, a record player, the TV, a café — and pull up the artwork automatically. • Optional lo-fi pixel-art styles: Game Boy, PICO-8, NES, CRT ramps and more, with retro ordered dithering — or keep the cover crisp. • Analog or digital clocks that crossfade with the art, a scrolling artist & title, and a song-progress bar. • Or hand off to the Pixoo's own built-in audio visualizer. CLOCKS • A collection of animated 64×64 clock faces — LCD, split-flap flip, matrix and more. • They tint themselves to match your album's colors. WEATHER • Local conditions powered by Apple Weather — current, hourly, daily and details, with smooth mosaic transitions. EFFORTLESS SETUP • Finds your Pixoo 64 automatically on the same Wi-Fi — or just enter its IP. • Preview everything live on your phone before you even connect a device. • "Dim screen" keeps it running while your phone sleeps, to save battery.
