About this app

A coin toss to decide your fate - but this time, you control the probability.

Normally, a coin toss is a fair 50/50 decision-making method. However, this app allows you to freely adjust the ratio between Heads and Tails. Whether you want fairness or intentionally biased simulations, this tool adapts to your needs.

Main Features:
- Customizable ratios: Set any probability you like, such as 60:40 or 80:20.
- Advanced randomness: Generates unpredictable results based on your chosen ratio.
- Simple interface: Minimal and intuitive design for anyone to use.

Fairness & Mathematics:
A fair coin has a theoretical 50% chance for each side. As the number of trials increases, the actual results approach the expected value - a principle known as the binomial distribution.

Use Cases:
- Decision-making: Perfect for quick choices or weighted conditions.
- Games & TRPGs: Use it as a probability-based event simulator.
- Education & statistics: Observe how results converge to the set probability through repeated trials.

Will you leave it to chance, or bend fate to your will? Try it now and let the coin decide!
