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.
