System Requirements Document (SRD)

Project Name: Regal-Mobile

1. Introduction

The Regal-Mobile project aims to recreate the user interface (UI) of an existing mobile application with precision and attention to detail. This document outlines the system requirements necessary to achieve this goal, ensuring a seamless user experience tailored to Saikumar's needs and preferences.

This SRD is designed to guide the development process for the Regal-Mobile project, incorporating locale-specific considerations for India (IN), such as currency, timezone (IST), and user expectations.

2. System Overview

The Regal-Mobile application will replicate the UI of the specified mobile app, ensuring that all screens, features, and interactions are identical to the original. The project will focus on delivering a visually appealing, intuitive, and responsive interface optimized for mobile devices.

Key objectives include:

• Exact replication of the target app's UI.
• Localization for Indian users, including support for INR currency and IST timezone.
• High performance and responsiveness across various mobile devices.

The system will be developed using modern technologies, ensuring scalability, maintainability, and ease of integration with backend services.

3. Functional Requirements

Story Points

• As User I should be able to view the replicated mobile app UI.
• As User I should be able to interact with all screens and features exactly as in the original app.
• As Admin I should be able to manage and update UI elements dynamically.
• As Guest I should be able to explore the app without requiring login credentials.

4. User Personas

1. User

• Primary audience of the app.
• Expects a seamless and intuitive experience.
• Uses the app for daily tasks or entertainment.

2. Admin

• Responsible for managing and updating UI elements.
• Requires tools for monitoring app performance and user feedback.

3. Guest

• Casual users exploring the app without committing to registration.
• Limited access to certain features.

5. Visuals Colors and Theme

Unique Color Palette for Regal-Mobile:

• Background: #F5F9FF (Soft sky blue for a calming effect)
• Surface: #FFFFFF (Pure white for clean and modern design)
• Text: #333333 (Dark charcoal for readability)
• Accent: #FF6F61 (Vibrant coral for interactive elements)
• Muted Tones: #B0BEC5 (Light gray-blue for secondary elements)

This palette is designed to evoke trust, simplicity, and elegance, aligning with the project's goal of replicating a professional mobile app UI.

6. Signature Design Concept

Interactive Floating Panels

The Regal-Mobile homepage will feature a bold and unforgettable design: Interactive Floating Panels.

Concept Details:

• Visuals: The homepage will display panels that appear to float in a 3D space, with subtle shadows and depth effects.
• Interaction: Users can swipe or tap to navigate between panels, which will animate smoothly with a "flip" or "slide" transition.
• Micro-interactions: Panels will react to user gestures with dynamic scaling, color shifts, and hover effects.
• Animations: The background will feature a soft gradient that subtly shifts colors based on the time of day (morning, afternoon, evening).
• First Impression: The landing page will immediately captivate users with its modern and interactive design, setting the tone for the rest of the app.

This design concept ensures that the Regal-Mobile app stands out while maintaining usability and functionality.

7. Non-Functional Requirements

• Performance: The app must load within 2 seconds on standard mobile devices.
• Scalability: Support for up to 1 million users concurrently.
• Security: Ensure data encryption and secure authentication mechanisms.
• Localization: Full support for Indian locale, including INR currency and IST timezone.
• Accessibility: Compliance with WCAG 2.1 standards for accessibility.

8. Tech Stack

Frontend

• React Native for mobile app development.

Backend

• Python with FastAPI for API development.

Database

• MySQL or MariaDB for relational data storage (using Alembic for migrations).

AI Models (if applicable)

• GPT 5.4 for user-friendly responses.
• Claude 4.6 Opas for coding assistance.

AI Tools

• Litellm for LLM routing.
• Langchain for advanced AI workflows.

Orchestration

• Docker and docker-compose for local development.
• Kubernetes for server-side orchestration.

9. Assumptions and Constraints

Assumptions

• The original app's UI design is accessible and can be replicated without legal or technical restrictions.
• Users in India prefer intuitive navigation and localized content.

Constraints

• The app must adhere to the original design without deviation.
• Development must be completed within the agreed timeline and budget.
