What we build
The site started with one job: give someone a quick heads or tails result without distractions. It now also includes a multiple coin flipper, a probability calculator, and a related yes or no generator.
How randomness works
Outcomes are generated on your device with the browser's secure random-number API. The visual animation does not decide the result. Each new coin is assigned one of two equal portions of the available random-number range. Our step-by-step randomness explanation shows the exact number range, midpoint, and JavaScript.
Privacy by default
Your personal flip totals remain in local storage on your device. The tools do not require an account, name, or email address. You can remove saved totals at any time with the reset button.
Editorial approach
Our explanations stay focused on coin flips, binary choices, and the probability behind them. We aim to make every page useful on its own rather than publishing unrelated random-generator content.
