jKey
Read full descriptionHide full description
jKey is an innovative iOS keyboard extension that revolutionizes text input through its unique cluster-based typing system. Rather than presenting users with a traditional QWERTY layout, jKey organizes characters into logical clusters that users can tap to expand and then select specific characters from. This approach makes typing more efficient and accessible, particularly for users who may have difficulty with traditional keyboard layouts. The keyboard operates in five distinct modes: letters, numbers, symbols, emojis, and snippets. Each mode presents characters organized into clusters, with the letters mode featuring five clusters containing related characters like "q,w,e,a,s,d" in the first cluster and "r,t,y,u,f,g,h" in the second. The numbers and symbols modes follow similar clustering principles, making character selection more intuitive and faster. One of jKey's most advanced features is its integration with Apple Intelligence for contextual word suggestions. On compatible devices running iOS 26 or later, the keyboard leverages Apple's on-device language model to provide intelligent word completions and next-word predictions. For older devices or when Apple Intelligence is unavailable, jKey automatically falls back to traditional suggestion methods using UILexicon and other iOS APIs. The keyboard includes sophisticated accessibility features designed to work seamlessly with VoiceOver. Every button has descriptive labels and hints, and the keyboard supports custom VoiceOver rotor actions for special functions like toggling caps lock, deleting words, lines, or all text. Users can customize the font size to their preference, ensuring the keyboard remains usable across different accessibility needs. jKey offers extensive customization options through its companion app. Users can create up to six categories of text snippets, with each category containing up to six snippets for quick text insertion. The emoji system is equally flexible, allowing users to choose from fifty predefined emoji groups or create custom collections of up to six groups with six emojis each. These predefined groups cover everything from basic smileys and expressions to specialized collections for different emotions, activities, and contexts. The keyboard's appearance is highly customizable, offering multiple color schemes including white on black, black on white, yellow on black, and black on yellow, plus the ability to create custom color combinations. Users can adjust font sizes from small to extra large, ensuring optimal visibility and usability. Smart features enhance the typing experience, including intelligent shift behavior where a single tap capitalizes one character while holding enables caps lock, and smart delete functionality that accelerates deletion speed the longer the delete button is held. The keyboard also includes auto-return settings that can be configured differently for each mode, allowing users to control whether the keyboard returns to the main cluster view after each character selection. jKey is built with modern iOS development practices, using SwiftUI for its companion app interface and UIKit for the keyboard extension. It supports iOS 17.0 and later for basic functionality, with Apple Intelligence features requiring iOS 26.0 and compatible hardware. The project includes comprehensive testing with unit tests covering data models, view models, keyboard functionality, and accessibility features.
