John's Color Scanner for iOS

John's Color Scanner is an educational iPhone application designed specifically for individuals with color vision deficiencies. By leveraging the device's camera, it captures real-time images to assist users in identifying colors. The app features a focused square sight to help users concentrate on specific objects or areas, making the color identification process more accurate and user-friendly.

In addition to its core functionality, John's Color Scanner includes practical features to enhance usability. A flashlight button allows users to toggle the device's light, improving visibility in low-light conditions. Additionally, the app offers a camera exposure locking feature, which is beneficial for capturing lighter and brighter colors accurately. As a free application, John's Color Scanner provides an intuitive interface and valuable assistance to colorblind individuals, making color identification more accessible.
