Rondo — Music Visualizer

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, tempo)
• 25 scenes that genuinely react to the music: console bars, a ring that
pulses on the kick, waveform orb, spectrogram, needle VU meters,
particle bursts, tunnel, liquid, lava lamp, LED equalizer, nebula,
kaleidoscope, a beatbox crew whose singer takes the mic when your lyrics
come in, a neon oscilloscope, a turntable wearing your artwork, a night
skyline — imaginary, or Paris, London, New York, Tokyo and eight more —
whose windows are the equalizer, a rhythm-game fretboard, a see-through
cassette, a eurorack wall, incense smoke… — plus two stickers for your
own video: a now-playing card and the track's waveform
• 18 backgrounds, from aurora, film grain and vinyl grooves to a synthwave
sunset and rain on a lake — two of them light (paper, halftone), turning
the whole palette over — plus a CRT effect over everything
• Release kit: one tap renders the teaser on the drop, the Spotify Canvas
looping on it and the full YouTube video. Send a track to Rondo from
another app (or a Shortcut on iPhone) and it lands on the kit
• Media: your own photos and videos, one after another over the track,
each with its share of it, its effects, its transition, and for a clip
the passage it plays — a film cut to your music. Or start from a video:
its sound becomes the track, its picture stays in sync behind the scene
• A scene timeline: one scene on the intro, another on the drop, each with
its own settings and a crossfade at the join
• Auto edit: one tap writes both timelines from what your track already
knows — a scene for each part, cuts on the downbeat, effects dosed by
section. All of it editable afterwards
• The shape of your track, named — intro, build, drop, groove, break,
outro — and its tempo: find the drop lands your teaser on the build,
and cuts and loops land on the bar
• Live mode: the scenes on the sound of the room — a studio session, a
set, a party. The microphone feeds the analysis in real time, nothing is
ever recorded, and over HDMI or USB-C the visuals move to a TV or a
projector. Free
• Room mode: the crowd scans a code, and every phone in the room plays
your look to the music it hears, all in time. No network, no account.
Free
• Synced lyrics: transcription on the device, a karaoke sweep, and a
proofread by your phone's own language model — the timings never move
• Your identity: artwork, title and artist name burned in, eight typefaces,
entrance animations, ten signed palettes, your brand colour — or the
colours of your artwork
• Widget mode: the scene in a movable frame, your photo or video around it
• Waveform trimming and fades; exports in 9:16, 1:1, 16:9 and Spotify
Canvas (a silent loop that closes on itself)
• Presets: six curated looks to start, and yours reused on every release
in one tap
• Set mode: chain your projects full screen and project them on a TV
(AirPlay, HDMI, screen mirroring) — or export the whole set as one video,
with YouTube chapters ready to paste
• 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.
