System Requirements Document (SRD)

Project Name: honest-windows

1. Introduction

The honest-windows project aims to deliver a web-based MVP for SlapWin, a fun and interactive sound-based application inspired by the Mac app "SlapMac." SlapWin is designed specifically for Windows users but will initially launch as a web-based version to validate the concept and gather user feedback.

This document outlines the system requirements for the web-based MVP, including mocked payment integration, mock email services, basic analytics, and a modern UI theme. The project is structured to allow seamless upgrades to a native Windows desktop application in the future.

2. System Overview

SlapWin is a playful web application that detects sound input (e.g., claps or taps/slaps on a laptop) and triggers sound effects. It operates on a freemium model, offering limited functionality for free users and unlocking premium features for paid users.

Key Features:

• Sound Detection: Detect claps or taps/slaps using microphone input.
• Sound Effects: Play sound effects when sound thresholds are crossed.
• Freemium Model:
  • Free version: 5 preloaded sound effects.
  • Premium version: 100+ sound effects, custom sound upload, and premium UI.
• Mock Payment Integration: Simulate Razorpay payment flow for premium unlock.
• Mock Email Service: Log email content in the backend and show confirmation in the UI.
• Basic Analytics: Track user activity using MongoDB.
• Modern UI: Fun, addictive, and visually appealing design with a strict orange/yellow/white color theme.

3. Functional Requirements

User Stories:

• As a User, I should be able to toggle the sound detection feature ON/OFF.
• As a User, I should be able to switch between different sound effects.
• As a User, I should be able to unlock premium features after a simulated payment.
• As a User, I should be able to upload custom sound effects (premium only).
• As a User, I should see a confirmation message after unlocking premium features.
• As a User, I should see a visually appealing UI with smooth animations.
• As a User, I should be able to interact with the app even if I have no coding knowledge.
• As an Admin, I should be able to view analytics data (number of users, premium unlocks, feature usage).

4. User Personas

1. Free User

• Access to 5 preloaded sound effects.
• Can toggle sound detection ON/OFF and switch sounds.
• Cannot upload custom sounds or access premium features.

2. Premium User

• Access to 100+ sound effects and custom sound upload.
• Enhanced UI experience with premium branding.
• Unlocks features after simulated payment.

3. Admin

• Monitors analytics data (user activity, premium unlocks, feature usage).
• Manages backend logs for email and payment simulations.

5. Visuals Colors and Theme

Color Palette:

• Background: #FFF8E1 (Soft Yellow)
• Surface: #FFE082 (Bright Yellow)
• Text: #212121 (Dark Gray)
• Accent: #FF7043 (Vivid Orange)
• Muted Tones: #BDBDBD (Light Gray)

Design Mood:

The UI should feel fun, interactive, and premium. Smooth animations and clean fonts will enhance the user experience, making the app addictive and visually appealing.

6. Signature Design Concept

Interactive Soundwave Visualization

The homepage will feature a dynamic soundwave animation that reacts in real-time to microphone input. As users clap or tap/slap their laptop, the soundwave will pulse and change colors based on the intensity of the sound.

Details:

• Animation: A flowing soundwave that morphs between the accent colors (#FF7043, #FFE082) based on sound intensity.
• Micro-Interactions: Hover effects on buttons that ripple outward like soundwaves.
• Transitions: Smooth fade-ins and slide-ins for UI elements.
• Interactive Elements:
  • A toggle switch styled as a glowing button.
  • Sound effect cards that flip when clicked, revealing details about the sound.

This design will make the app feel alive and engaging, leaving a lasting impression on users.

7. Non-Functional Requirements

• Performance: The app should respond to sound input within 100ms.
• Scalability: The backend should support up to 10,000 users.
• Security: User data (email, phone) must be stored securely in MongoDB.
• Accessibility: The UI should be intuitive for non-technical users.
• Cross-Browser Compatibility: The app must work on Chrome, Edge, and Firefox.

8. Tech Stack

Frontend:

• HTML, CSS, JavaScript

Backend:

• Python (Flask)

Database:

• MongoDB

Sound Detection:

• Python sounddevice library

Packaging:

• Structured for future transition to PyInstaller for native Windows app.

Analytics:

• MongoDB for basic analytics tracking.

9. Assumptions and Constraints

Assumptions:

• Users will access the app via modern browsers.
• The app will initially use royalty-free placeholder sounds.
• Payment and email services will remain mocked during MVP development.

Constraints:

• Limited to basic analytics and mock integrations for MVP.
• No login system; authentication is based on email and phone collection.

10. Glossary

• MVP: Minimum Viable Product.
• Mock Integration: Simulated functionality for testing purposes.
• Sound Detection: Identifying sound input via microphone.
• Freemium Model: A pricing strategy offering basic features for free and advanced features for paid users.
• MongoDB: A NoSQL database used for storing analytics and user data.
• Razorpay: An Indian payment gateway for online transactions.
