1. Project Overview:

   • Briefly describe the purpose and goals of the project.
   • Specify the technologies to be used: React Native for the mobile app, Node.js for the backend, and PostgreSQL for the database.

2. User Registration and Authentication:

   • Implement user registration and login functionality to allow users to create accounts and authenticate themselves.

3. Location Tracking:

   • Integrate location tracking functionality into the mobile app using React Native's Geolocation API.
   • Continuously track the user's position and movement while they are on the piece of land.

4. Drawing Perimeter:

   • Develop a feature that draws a perimeter based on the user's movement and position.
   • Use the collected location data to create a path or boundary that represents the user's movements.

5. Data Storage and Retrieval:

   • Set up a PostgreSQL database to store the user's location and perimeter data.
   • Design the appropriate database schema to efficiently store and retrieve the necessary information.

6. API Development:

   • Build a RESTful API using Node.js to handle communication between the mobile app and the database.
   • Implement endpoints for user authentication, location tracking data, and perimeter data.

7. Data Visualization:

   • Create visual representations of the user's movements and perimeter on the mobile app.
   • Utilize mapping libraries (such as Mapbox or Google Maps) to display the user's position and the drawn perimeter.

8. Error Handling and Validation:

   • Implement robust error handling and validation mechanisms to ensure the app's stability and prevent data inconsistencies.

9. User Interface (UI) Design:

   • Design an intuitive and user-friendly interface for the mobile app.
   • Pay attention to usability, responsiveness, and accessibility guidelines.

10. Testing and Quality Assurance:

    • Conduct thorough testing of the mobile app to identify and fix any bugs or issues.
    • Perform unit testing, integration testing, and user acceptance testing to ensure the app functions as intended.

11. Deployment and Maintenance:

    • Prepare the app for deployment to an app store (e.g., Google Play Store, Apple App Store).
    • Continuously monitor and maintain the app to address any potential issues and incorporate user feedback.

Remember to break down each section into smaller tasks and assign them to your team members accordingly. Regularly communicate and collaborate to ensure smooth progress throughout the project. Good luck with your app development!
