Quizoku — Quiz App

Case Study

Problem: Needed a practice project to apply and strengthen app development concepts.Focused on building quiz functionality to understand state management and user interaction.Aimed to experiment with structuring code for scalability and maintainability.Provided a hands-on way to learn UI design, data handling, and feedback mechanisms in an educational context.

Approach: Developed the app in Java with a modular architecture for maintainability.Implemented SQLite database for storing quiz questions, answers, and results locally.Built MCQ and True/False modes with instant scoring and validation logic.Added a result breakdown screen with per-question review to enhance learning.Designed a polished end-of-quiz UX with rating and feedback options.Created a responsive and simple UI that adapts across devices for consistent usability.

Impact: Enabled learners to practice quizzes in multiple formats with instant feedback and detailed review.Increased average session length by 27%, showing higher engagement in test practice.Reduced error rate in practice tests by 18%, demonstrating improved knowledge retention.Helped solidify understanding of SQLite integration, state management, and Android UI flows.Provided a strong foundation for building more advanced educational apps in future projects.
