SonifEye is a sensory tool that makes the visual element of color accessible through sound. SonifEye transforms the colors of your photos into musical notes, and it teaches you to recognize this color by ear. You can take your time to learn the color-to-sound associations at your own pace. There is a challenge mode that increases in difficulty as you play by evolving and tailoring itself to your skill level. Whether you're blind, low-vision, curious about synesthesia, or just eager to explore a new kind of perception—SonifEye offers an interactive, accessible way to explore and learn to hear the colors all around you. SonifEye is simple to use. Take a photo or upload one from your gallery. Tap it, and SonifEye begins to compose its color as sound. This composition isn't random—our curated mappings ensure each color corresponds to a unique musical identity. For further exploration into the colorful world of your images, use any of the built-in tools: • Color Touch – Glide your finger or stylus across an image to collect and play clusters of color • Color Reveal – Break down an image into discrete, tappable color blocks to play and explore • Crop & Focus – Zoom in on specific parts of an image for extraction and to hear those parts in isolation Hearing color is a skill—and SonifEye helps you build it. Our Challenge Mode trains your brain to match musical notes with color through rewarding, bite-sized quizzes. Increase your color-hearing skill with every tap—the more you play and improve, the more advanced and nuanced the challenges become. What SonifEye offers: • VoiceOver Compatibility – Descriptive tutorial and tap-by-tap guidance for every interaction • Color-Blind Accessibility – Built-in, direct labels that uniquely identify color by it's hue, tint, and shade • Color Sonification – Tap any photo to hear its component colors • Challenge Mode – Practice hearing color through guided, low-pressure quizzes • Adaptive Challenge Difficulty – Unlock new challenges as you improve and get a refresher on old challenges as you go • Color Exploration Tools – Crop, reveal, and touch-explore color details • Privacy Focus – Your photos stay private and are never shared with the developer or other users With SonifEye, color isn’t silent. Experience this visual element like you never have before. It’s not about what you see—it’s about what you sense.

Synesthesia SoundCam

Features
Read full description

Film something. Hear it play. Synesthesia SoundCam turns a 5–15 second clip into a vertical music video. The colors in the scene compose the music: when the color, the light or the shot changes, the music changes too, on the beat. HOW IT WORKS • Film 5 to 15 seconds, or import a video from your library • While you film, the screen reacts to the colors the camera sees • A few seconds later you hear the preview with the music composed for your video • Export a vertical 9:16 MP4 and share it, or save it to Photos SOUND DIRECTION • Three interpretations of the same video — Calm, Cinematic and Pulse — to hear and choose without filming again. In all three, every change of scene changes the music. • Sound Identity: pick a sound and a motif (Glass, Velvet, Neon or Wood) that come back in your videos, while harmony, rhythm and changes follow each scene’s colors. • For imported videos with their own sound: music, mix or original sound, levelled and free of clipping. • Optionally, the exported video shows “music from colors”, with the color strip moving along with the music. THE MUSIC The music is generated on your phone by the app’s own engine (synthesis and the app’s own AURA sound loops), from the colors found along the whole video. The preview and the exported video carry exactly the same audio. The microphone is never used. FREE AND PRO Your first 3 videos export free in 720p with a discreet Synesthesia signature. Interpretations and sound identities can be tried for free. With Synesthesia PRO, exports are unlimited, in 1080p and without the signature, and you can keep your sound identity for your next videos on this device. PRO also includes the sound diary benefits: watermark-free cards, premium sounds, exclusive filters, custom MP3s and sonic QR prints. Monthly and annual auto-renewable subscriptions are available; prices and any offers are shown directly by the App Store. ALSO IN THE APP The menu still holds the sound photo diary, the daily challenge, playlists, the map and manual sound mapping. PRIVACY No account. Your videos stay on your phone until you share them. The app only sends anonymous usage statistics (for example “video exported”) with no content and no identifiers, and you can turn them off in the menu. Payment is charged to your Apple ID at confirmation. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.
