Progress Tracker App

A smart learning companion designed to make studying more effective and boost long-term retention. The application is built with an Android frontend and a Spring Boot backend, demonstrating a complete client-server architecture.

🌟 Impact

This application solves the common problem of inconsistent learning and forgetting what you've studied. By providing a structured way to track daily study topics and implementing a smart, spaced-repetition revision system, it aims to make learning more effective, reduce procrastination, and ensure that knowledge is retained for the long term.

🚀 Features

• Daily Study & Goal Tracking: Log daily study topics or general goals with titles and descriptions.
• Smart Revision System: Automatically schedules revision reminders for topics based on a spaced repetition formula (e.g., after 1, 3, 7, and 15 days).
• Revision Dashboard: A dedicated screen to keep track of all topics that are due for revision, so nothing is ever missed.
• Notes Section: A separate tab for taking and organizing study notes related to specific topics.
• Progress Management: Mark goals/tasks as complete and delete them when they are no longer needed.
• Centralized Architecture: All data is stored on a central server, making the app scalable and ready for future multi-device support.

🏛️ Architecture

This application follows a modern client-server architecture:

• Frontend (Android Client): A native Android application responsible for the user interface and user interaction. It communicates with the backend via RESTful API calls.
• Backend (Spring Boot Server): A robust server that exposes a set of RESTful APIs to handle all business logic (Create, Read, Update, Delete) and data persistence.
• Communication: The client and server communicate over HTTP using JSON as the data exchange format. The Android client uses Retrofit for efficient and clean network requests.

🛠️ Tech Stack

🏁 Getting Started

To get a local copy up and running, follow these simple steps.

Prerequisites

• Java 17 or higher
• Android Studio (latest version)
• An IDE for Java/Spring (like IntelliJ IDEA or VS Code)
• An Android Emulator or a physical device

1. Backend Setup

1. Open the Spring Boot backend project in your IDE (e.g., IntelliJ IDEA).
2. Let the IDE resolve the Maven dependencies.
3. Run the ProgressTrackerBackendApplication.java file to start the server.
4. The server will start on http://localhost:8080.

2. Android App Setup

1. Open the Android project in Android Studio.

2. Let Gradle sync the project dependencies.

3. Important: Ensure your ApiClient.java is pointing to the correct local address for the emulator:

   // in app/src/main/java/com/example/progresstracker/network/ApiClient.java
   private static final String BASE_URL = "http://10.0.2.2:8080/";

4. Run the app on an emulator or a physical device connected to the same WiFi network as your computer.

   • Note: If using a physical device, replace 10.0.2.2 in BASE_URL with your computer's local network IP address (e.g., http://192.168.1.10:8080/).
