The Problem Every Group Faces 🤷‍♀️

Group decisions can feel like navigating a minefield. Do you go with majority vote? Compromise? Flip a coin? Our app introduces a smarter, more engaging solution that brings both fairness and fun to decision-making.

What Makes This App Special? 🌟

This isn't just another random selector. It's a sophisticated decision-making tool that:

  • Allows weighted option selection
  • Creates a visually engaging spinning wheel
  • Tracks decision history
  • Supports dark/light mode
  • Works seamlessly across devices

Key Concepts Behind the App 💡

Weighted Randomness: Not Just Luck

Traditional random selection treats all options equally. Our approach? Weighted randomness.

  • Each option gets a "weight" between 1-10
  • Higher weight = Higher chance of selection
  • Introduces nuanced decision-making
  • Perfect for scenarios with subtle preferences

Technical Architecture 🖥️

Frontend Technologies

  • HTML5 for structure
  • CSS3 for responsive design
  • Vanilla JavaScript for dynamic interactions

Core Features

Users can:

  • Input decision options
  • Assign custom weights
  • Visualize options instantly

Our wheel isn't just eye candy. It's a mathematically precise selection mechanism that:

  • Dynamically renders based on options
  • Animates with smooth rotation
  • Selects winner using weighted probability algorithm

Every spin gets recorded, allowing users to:

  • Review past decisions
  • Understand selection patterns
  • Create a fun decision log

Algorithm Breakdown 🧮

The selection process involves:

  1. Calculate total weight of all options
  2. Generate a scaled random number
  3. Iterate and accumulate weights
  4. Select corresponding option

Real-World Use Cases 🌍

  1. Team Project Assignments 💼
  2. Weekend Activity Planning 🏕️
  3. Restaurant Selection 🍽️
  4. Study Group Task Distribution 📚
  5. Friend Group Event Choosing 🎉
