System Requirements Document (SRD) for orbit-app

1. Introduction

The orbit-app is a streamlined, user-friendly to-do application designed to help users efficiently manage their tasks. The app will focus on simplicity and functionality, providing only two core pages: a login page and a main dashboard for task management. This document outlines the system requirements for the development of orbit-app, tailored to meet the needs of users in the US, with locale-specific defaults such as time zones (EST as default) and date formats (MM/DD/YYYY).

2. System Overview

The orbit-app is a lightweight to-do application that prioritizes ease of use and minimalism. The system will allow users to log in securely and manage their tasks through a single, intuitive dashboard. The app will support task creation, editing, deletion, and categorization, ensuring users can stay organized without unnecessary complexity.

Key features include:

• Secure user authentication.
• A clean, responsive dashboard for task management.
• Support for task categorization and prioritization.

The app will be accessible via web browsers and optimized for both desktop and mobile devices.

3. Functional Requirements

• As a User, I should be able to log in securely using my credentials.
• As a User, I should be able to create new tasks.
• As a User, I should be able to edit existing tasks.
• As a User, I should be able to delete tasks.
• As a User, I should be able to categorize tasks.
• As a User, I should be able to view all my tasks in a clean, organized dashboard.

4. User Personas

1. User:
   • Primary user of the app.
   • Needs a simple and efficient way to manage tasks.
   • Values security, speed, and ease of use.

5. Visuals Colors and Theme

The orbit-app will feature a modern and minimalistic design with the following color scheme:

• Primary Color: Deep Space Blue (#1E3A8A) - for headers and key elements.
• Secondary Color: Orbit Gray (#F3F4F6) - for backgrounds and secondary elements.
• Accent Color: Stellar Yellow (#FBBF24) - for buttons and highlights.
• Text Color: Cosmic Black (#111827) - for primary text.
• Error/Alert Color: Red Nova (#EF4444) - for error messages and alerts.

The theme will emphasize clarity and simplicity, with a focus on usability and accessibility.

6. Signature Design Concept

The orbit-app homepage/dashboard will feature a dynamic "orbiting tasks" animation.

Concept Details:

• The dashboard will have a central "planet" icon representing the user, with tasks visually represented as orbiting satellites around it.
• Tasks will "orbit" in a circular motion, with their distance from the center indicating their priority (closer = higher priority).
• Hovering over a task will pause its orbit and display a tooltip with task details.
• Clicking on a task will open an editing modal with smooth transitions.
• The background will feature a subtle animated starfield, giving the app a futuristic and engaging feel.
• The login page will feature a "launchpad" theme, with a countdown animation as the user logs in, transitioning seamlessly to the dashboard.

This unique design will make the app visually striking and memorable while maintaining functionality.

7. Non-Functional Requirements

• The app must load within 2 seconds on a standard broadband connection.
• The app must be responsive and work seamlessly on both desktop and mobile devices.
• The system must support at least 10,000 concurrent users.
• The app must comply with accessibility standards (WCAG 2.1 AA).
• All user data must be encrypted both in transit and at rest.

8. Tech Stack

Frontend:

• React for Web.

Backend:

• Python with FastAPI.

Database:

• MySQL with Alembic for migrations.

AI Tools:

• GPT 5.2 for user-friendly responses (if applicable in future iterations).

Local Orchestration:

• Docker and docker-compose.

Server-Side Orchestration:

• Kubernetes.

9. Assumptions and Constraints

• The app will only have two pages: a login page and a dashboard.
• The app will be developed for the US market, with English as the default language and EST as the default timezone.
• The app will not include advanced features such as notifications or integrations with third-party services in its initial version.
• The app will prioritize simplicity and usability over feature richness.

10. Glossary
