Using customizable icons and damage relationships, we aim to help users learn the different damage ratios for various elements. Also enables the user to choose the elements combined to see the reactions. Purpose and Target Audience - This app is designed for users who have basic coding knowledge or are actively learning about data formats such as JSON and CSV. The main purpose of the app is to help these users visualize and calculate relationships between different elements — for example, which elements are strong or weak against others. Users can also design and customize their own “elemental chart” to explore and simulate how element combinations interact. The target audience includes: - Learners who want to understand how JSON and CSV data structures can be applied to visual and interactive projects. - Game designers or hobbyists who are creating their own elemental systems and want to test balance and effectiveness. - Apple Watch users who want a quick and interactive visualization of element relationships. App Functionality and How It Works - The user prepares or imports a JSON file that defines elements and their relationships (for example, fire > grass, water > fire). - The app reads and parses the JSON data to display each element’s strengths and weaknesses visually. - The user can combine one or two elements to calculate their combined damage ratio against other elements. - The calculation result is then visualized as an element interaction chart or numerical ratio. - The result is displayed directly on the Apple Watch in a simple visual format for quick reference. - All data is processed locally on the device.
