Inspiration

We wanted a modern, interactive, and accessible way to study the Westminster Shorter Catechism. Students, teachers, and parents often struggle with static text, so we combined a bilingual interface, quizzes, text-to-speech, and AI Tutor for guided learning.

  • React Native + TypeScript for cross-platform apps.
  • TailwindCSS for clean and modern UI.
  • Text-to-Speech for auditory learning.
  • Interactive quiz module with randomized questions.
  • Gemini 3 AI Tutor for real-time guidance.

Challenges

  • Balancing bilingual content while keeping interface clear.
  • Making AI Tutor interactions accurate and encouraging.
  • Designing quizzes that are challenging but not discouraging.
  • Ensuring smooth Text-to-Speech playback across devices.

Accomplishments

  • Complete modern redesign for cross-platform use.
  • Interactive learning tools: quizzes, AI Tutor, and text-to-speech.
  • Bilingual support for English and Chinese speakers.
  • Guided, structured, and motivating learning experience.

What's Next

  • Expand AI Tutor capabilities for complex theological questions.
  • Add spaced repetition and smart quiz suggestions.
  • Introduce progress tracking and streaks to motivate daily study.
  • Explore additional translations and accessibility features.
  • Refine interface design for smoother, more intuitive learning.
