I’m building a focused study tool for pulmonary medicine and need a complete Android application that combines interactive learning with quick-access notes. The core of the app is a bank of multiple-choice quizzes covering every major topic in pulmonology. Alongside each question set, I want concise, scroll-friendly notes and reference material so users can review explanations or jump straight to theory before retesting themselves. To keep learners engaged, the app should quietly log their scores, highlight weak areas, and present simple progress charts so they can watch improvement over time. Because we’re dealing with a single medical specialty, the interface can be streamlined—no subject picker required—just a clean landing screen that flows into “Study Notes”, “Take Quiz”, and “Progress”. I’m happy with a modern Android stack (Kotlin + Jetpack recommended), but I’m open to your preferred framework as long as it delivers smooth offline use and quick updates for new question packs. Material Design components, Room or realm for local storage, and a lightweight analytics layer for progress tracking will do the job nicely. Deliverables • APK plus full source code in a public or private Git repo • Structured question database (CSV/JSON/SQL) with sample pulmonology items and placeholder notes so I can add more later • Simple dashboard showing accuracy by topic and overall score history • Brief README explaining build steps, key modules, and how to extend the question set If you’ve created exam prep or medical reference apps before, show me a link or APK—otherwise, tell me how you’d architect the quiz engine and note viewer. Looking forward to collaborating on this focused learning tool.
