Rondo — Music Visualizer

Your music never leaves your phone: analysis, rendering and export are 100% on-device. Teaser, Spotify Canvas and YouTube visualizer in minutes.

You just finished a track. You need a teaser for Instagram, a Canvas for Spotify, a video for YouTube — now, not next week.

Rondo turns your audio into animated visuals, directly on your phone. No upload, no account, no server: your unreleased master stays with you. It works in the studio with no signal, and on a plane.

WHAT IT DOES • Analyses your track on the device (kick, mids, highs, spectrum) • 13 scenes that genuinely react to the music: console bars, a ring that pulses on the kick, waveform orb, spectrogram, needle VU meters, dot rain, particle bursts, tunnel, liquid with kick ripples, lava-lamp blobs, LED equalizer with peak-hold, slow-swirling nebula, kaleidoscope • 11 backgrounds: gradient, aurora, film grain, amp glow, waves, haze, oscilloscope sweep, vinyl grooves, retro sun-and-road, pixel dithering, hyperspace — plus a CRT effect over everything • Your identity: artwork, title and artist name burned in, four typefaces, entrance animations, your brand colour • Find the drop: the app spots the most energetic passages and lands your teaser on them • Waveform trimming, fade in and fade out • Exports in 9:16, 1:1, 16:9 and Spotify Canvas (a silent loop that closes on itself) • Presets: reuse the same look on every release, in one tap • Backup to YOUR iCloud — not to our cloud

NO SUBSCRIPTION The free version exports without a watermark. Rondo Pro is a one-time purchase that unlocks every scene and background, the 1:1, 16:9 and Canvas formats, brand identity and presets.

WHO IT IS FOR Beatmakers posting snippets, independent artists on release day, podcasters and labels rebuilding the same look every week, DJs putting their sets online.
