Retro Spectrum turns your phone into a retro audio display for your car or your desk. Mount your phone, play music through your speakers, and watch a real-time spectrum analyzer light up in the style of classic 80s–90s car stereos. Built for JDM and neo-classic car fans, and just as good as an always-on visualizer on your desk. NEW: VU METER SKINS Three skins that put VU meters and a spectrum analyzer on one screen. A VU meter follows the overall loudness, while a PEAK meter catches the loudest band instantly—so you can read how the music moves. When a song is recognized, its artwork shows behind the spectrum. • Analog VU — a classic car-stereo display with dot-matrix text, fan-shaped LED VU/PEAK meters, and an amber spectrum • LED Matrix — the whole screen is one LED board, artwork included • Racing HUD — a tachometer-style VU gauge and shift lights, straight out of a racing game MOTION SKINS Skins that don't just react to your music—they travel with it. They estimate the genre from what the mic hears and use song info when available, so no two shows are ever the same. • Rezolution — fly nonstop through a wireframe cyberspace. As the music builds, detail and distant views emerge, and at top speed it hits OVERDRIVE. • Rezonance — cruise an endless foggy highway under a clean white HUD. Pure chill for the long drive home. Motion skins are graphically intensive and may run warm on older devices. HOW IT WORKS Retro Spectrum listens through your device's microphone and analyzes the sound in real time. Because it uses the mic, it reacts to ANY source playing through your speakers—streaming, radio, CD, anything. No cables, no pairing. Important: it responds to sound from SPEAKERS, not headphones or earphones. Point your phone toward the speakers and turn the volume up. RETRO SKINS Switch between display styles inspired by legendary in-dash stereos: • VFD Green — a fluorescent-tube display (included free) • Plasma Orange — spinning-CD deck with artwork and a big clock • JDM Night — KENWOOD-style dual-zone EQ with 7-segment clock • Bubble Grid — synthwave neon grid with a perspective floor • Wireframe LCD — Y2K retro-future tunnel HUD • Gaming RGB — flowing RGB bars with mirror reflections Every skin works in both portrait and landscape. NOW PLAYING See the song that's playing right now. When you use Apple Music, the title, artist, and artwork are read directly from the system for instant accuracy. For any other source, Retro Spectrum identifies the track from the mic using Shazam technology. Double-tap to look up a song on demand. SHARE THE MOMENT Tap the artwork to turn your current skin and song into a share card for Instagram Stories and more. DESK MODE A built-in clock, date, and battery readout make Retro Spectrum a great always-on display for your desk setup—a glowing retro visualizer and clock in one. Choose 24-hour or 12-hour time with AM/PM. PRIVACY Microphone audio is analyzed on your device and is never recorded or saved. Song recognition can be turned off anytime. See our privacy policy for details. FREE + THREE PACKS The app and the VFD Green skin are free. The other skins come in three packs, each a one-time purchase: • Skin Pack #1 — five retro skins • Skin Pack #2 — three VU meter skins • Motion Pack — Rezolution and Rezonance The three packs are sold separately.
