I need an Android-only application that serves as an all-in-one study companion powered by AI. The app must handle three core jobs for students: • Homework help: users type or snap a photo of a question in Mathematics, Science, or Language Arts and receive step-by-step solutions, explanations, or essay outlines. • Test preparation: adaptive practice quizzes, flashcards, and progress analytics generated on the fly from the same three subjects. • Note organizing: an embedded scanner or text import that uses NLP to summarise, tag, and file notes so they are searchable by topic or keyword. A clean, distraction-free UI is essential, and everything should run smoothly on modern Android phones (API 26+). I’m open to Java, Kotlin, or a cross-platform stack such as Flutter, as long as the final APK is stable and Play-Store-ready. Feel free to integrate services like OpenAI, TensorFlow Lite, or your preferred on-device model for the AI layer; just make sure responses are fast and can work at least in a limited offline mode. Deliverables 1. Full Android source code with clear comments. 2. Compiled, signed APK ready for upload. 3. Brief setup guide and model/endpoint configuration notes. 4. Two-week post-handover bug-fix window. I’ll review builds against accuracy of answers, stability, and overall UX. Looking forward to seeing how you bring this study assistant to life.
