Imajourn
Read full descriptionHide full description
Imajourn turns sound into shape. Touch the water and every ripple sings. Hum a note and the pattern blooms. Draw any shape, type your name or choose a photo, and hear where it rings. Every sound has a shape, and you can keep it. PLAY • Water: touch for ripples and notes, drag to strum the scale, two fingers for interference. • Hum: your voice drives the water; hold a note steady and the figure locks in. • Tones: sweep a pitch strip through the notes; the ones where your shape resonates glow. • Listen: music and claps in the room become drops. • Plate: sand leaps from the moving parts of a ringing plate and settles on the still lines, the figures Ernst Chladni drew in 1787. • Room: sound in three dimensions. Light gathers on the still surfaces of a ringing sphere, cube or cylinder, or watch live waves travel from a clap, reflect off the walls and build standing waves, even inside a 3D model you import, shaded so you can see in (Pro). MAKE • Your shape: draw one in a single stroke, type a word, pick a photo or import an SVG (Pro: words, photos and files). • Set any shape inside a circle or polygon: its outline becomes a wall, with water inside and around it. • Draw walls, lenses and sponges into the water: double slits, lenses that focus, soft edges. • Tone sources, symmetry, wave speed and linger, 13 palettes, four voices, eleven scales and a reverb from dry to cathedral. KEEP AND SHARE • Capture stills, or hold the shutter for a clip with sound, in Water, Plate and Room: vertical for Stories and Reels, or the shape of your screen. Save to Photos or share. • Keep the moment: turn it on and Imajourn always holds the last 30 seconds, so you can save something beautiful after it happened. Only Imajourn's own sound is kept, never your microphone. • Keep scenes in your Library and share them as links anyone can open. CALM AND CURIOUS • Discoveries: find reflection, reverberation, interference, beats, resonance, the double slit and more, each with a one-line explanation. • Today's Resonance: a daily puzzle. Match the figure by choosing the plate and the note. • Drift: the scene plays itself, fades out and goes dark when the timer ends (15 minutes free). • On your TV: AirPlay to an Apple TV or AirPlay TV and the water fills the big screen, while your iPhone stays the instrument. • Sensory mode: softer light and calmer palettes. FOR EVERYONE • Feel the waves: on iPhone, haptics follow the water under your finger, so patterns can be explored by touch. • Full VoiceOver support, with a Describe action that speaks the scene and plays its notes. • Dynamic Type, Reduce Motion and Reduce Transparency respected. • In ten languages: English, Spanish, French, German, Italian, Brazilian Portuguese, Japanese, Korean, Simplified Chinese and Hindi. PRIVATE BY DESIGN Imajourn listens only while the microphone is on. Audio is analysed on your device and is never recorded or sent anywhere. No account, no ads, no tracking. IMAJOURN PRO, ONE PURCHASE, YOURS TO KEEP • Every shape and plate, plus your words, photos and SVG files as shapes • All voices and scales • Energy and Caustics views and every palette • Room: 3D Chladni figures, and live waves in a sphere, cube, cylinder or your own 3D model • Clips up to 3 minutes at full resolution without the mark, 2× stills, unlimited Library and Drift Pro is a single in-app purchase with no subscription. If you bought it before, it's already yours.
Chromophone

Chromophone turns whatever is playing in the room into a living psychedelic picture. Play, sing, or put a record on: the visuals follow the sound as it happens. Every frame is built from the sound arriving right now. Low frequencies swing the whole shape, mids and highs cut the detail, sharp hits snap the pattern into a new one, and the mood of the music slowly steers color and scale. When the room falls quiet, the picture fades to black. Nothing is prepared in advance and no video file is playing behind the screen. The picture is generated on the device from what it hears at that moment, so what you see belongs to that moment in the room. WHERE PEOPLE USE IT Watching sound become picture. Put the phone down while music plays and let the room draw itself. On stage. Mirror the screen to a projector or a TV and let the visuals run through the whole set; the screen stays awake while it plays. In a stream. Keep a live backdrop moving behind a set instead of a looping clip that ignores the music. While you play. Point it at an amp, a piano or your own voice and watch what you are playing take shape. TWO THINGS TO KNOW BEFORE YOU START It makes no sound of its own. It listens, and the music comes from wherever you already play it: your playing, your voice, or a speaker across the room. It takes the system audio input, so a line from an external interface arrives exactly as a microphone does. In a silent room the screen goes dark, because nothing is ever faked. It draws for the moment, not for later. There is no export and no rendering: this is a live picture while the music is happening, not a clip to publish afterwards. NOTHING LEAVES THE DEVICE The app contains no networking code at all. Audio is analyzed on the device, frame by frame, and is never recorded, never stored and never sent anywhere. Switch on Airplane Mode and everything still works exactly the same. FOR PEOPLE WHO SEE SOUND If you have ever wanted music to look like the way synesthetes describe it, or watched sand jump into patterns on a Chladni plate, this is that idea driven live by the room around you.

Verdict
The clearest difference is in-app purchases: Chromophone at none against Imajourn's 1. Chromophone also leads on update cadence (every 3 weeks vs every 11 months). On price, ads, device support and iOS requirement there is nothing between them.
