About the Coin Flip tool
Flip a single coin, or set the count to flip many at once with a running tally of heads and tails.
Flips use a cryptographically secure random source, so the distribution is fair — about 50/50 over time, with normal short-run streaks.
Everything runs locally in your browser: no data is uploaded, no account is needed, and it works offline once the page has loaded.
