Jiin The OFF App is a mobile web application designed to support individuals who experience recurring worry about everyday tasks (e.g., turning off appliances, taking medication). Built with HTML, CSS, and JavaScript, the app provides a lightweight, reassuring interface centered around a light-switch metaphor for marking tasks as “on” or “off.”
Users can register personalized tasks such as “Turn off the oven” or “Take medication,” set reminders, and optionally upload photos as evidence of completion. Core features include toggle-based task controls, customizable labels, photo attachments, and light/dark modes to accommodate user preferences. By reducing interaction steps and offering a clear, symbolic confirmation of completion, the OFF App is designed to increase users’ sense of control and reduce anxiety around routine task management.
