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. 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 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. 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. 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 + SKIN PACK The app and the VFD Green skin are free. Unlock all the other skins with a single one-time Skin Pack purchase.

Verdict
The clearest difference is in-app purchases: Lyrio at none against Retro Spectrum's 1. Lyrio also leads on update cadence (every 3 days vs every 3 weeks). Retro Spectrum's advantage is iOS requirement (16.0 vs 26.0). On price, ads and device support there is nothing between them.
