Language Learning Flashcard App (Spaced Repetition)

This project is an Android flashcard application for language learning that implements a spaced-repetition scheduling algorithm (similar to SM-2, used by Anki) to decide when each flashcard should be reviewed again based on how well the user recalled it.

Users create decks of word/translation pairs (or import a CSV word list), and during a review session, self-rate their recall (Again, Hard, Good, Easy) after flipping each card; the app then reschedules that card's next review date accordingly and stores the updated interval in Room.

A progress dashboard shows cards due today, review streaks, and a retention-rate chart over time (MPAndroidChart), and the app supports multiple decks so a user can study several languages or subjects independently.

Detailed Project Description

Language Learning Flashcard App (Spaced Repetition) gives the user a focused everyday tool with a clean interface, local storage of their data and optional sync or reminders.

How It Works
1. The user enters or records data (amounts, steps, notes, recordings, values).
2. The app validates and stores it locally (SQLite/Room/SharedPreferences) or in the cloud.
3. Lists, totals, charts or conversions are computed and displayed instantly.
4. Reminders/notifications run in the background where the feature applies.

Technology Roles
- Android
- Java
- Room
- Spaced Repetition
- MPAndroidChart

Implementation Steps
1. Sketch the screens and the data each screen needs.
2. Create the project in Android Studio, Room, MPAndroidChart and set up navigation between screens.
3. Define the local data model (SQLite/Room/SharedPreferences) or cloud sync.
4. Implement the core feature (tracking, conversion, recording, reminders, playback).
5. Add background work / notifications / permissions where required.
6. Test on real devices, handle edge cases and optimise battery and performance.
7. Generate the APK and prepare screenshots and documentation.

Key Features
- Simple, fast UI
- Offline storage
- Summaries and charts
- Notifications / sync where applicable

Expected Output
On completion the student will have an installable app that keeps the user's data organised and accessible.

Deliverables
- Complete source code with comments
- Database schema / data model and screen flow
- Project report with screenshots and results
- Demonstration-ready build
