🚀 Getting Started

Prerequisites

Make sure you have:

• Node.js
• npm or Yarn
• Python 3.8+
• React Native development environment
• Android Studio for Android development
• Xcode for iOS development on macOS

1. Clone the repository

git clone https://github.com/Vicky270506/Smart-Task-Manager.git
cd Smart-Task-Manager

2. Set up the backend

Create a Python virtual environment:

python -m venv .venv

Activate it on Windows PowerShell:

.\.venv\Scripts\Activate.ps1

Install the dependencies:

pip install -r SMT_server/requirements.txt

Start the Flask server:

cd SMT_server
python app.py

3. Set up the React Native application

Open another terminal:

cd SmartTaskManager
npm install

Run on Android:

npx react-native run-android

For iOS on macOS:

npx react-native run-ios

4. Optional: Generate demo data

cd SMT_server
python generate_data.py

🤖 How the AI Works

The application uses machine learning to make task management more intelligent.

Task Duration Prediction

The system estimates how many minutes a task may require using the trained duration prediction model.

Priority Prediction

The application analyzes task information to estimate its priority or urgency.

Smart Scheduling

A Reinforcement Learning environment uses a DQN agent to recommend suitable time slots for pending tasks based on the user's productivity patterns.

Continuous Learning

When a user completes a task, the actual completion time can be sent back to the backend. This feedback can be used to retrain the models and improve future predictions.

📊 Productivity Insights

The application provides productivity information such as:

• Weekly task summaries
• Completion patterns
• Productivity trends
• Personalized scheduling recommendations
• Learned productive time slots
