About
Toolio's Coin Flip uses the Web Crypto API (crypto.getRandomValues) to generate a truly random result on every flip — far more reliable than Math.random(). Results are tracked in a tally with percentage breakdowns and a visual history strip of your last 30 flips. Your flip history is saved locally in your browser so you can pick up right where you left off, even after closing the tab. Because everything runs client-side, your data never leaves your device.
How to use
- Click the '🪙 Flip' button or tap the coin directly to start a flip.
- Watch the coin spin and land on Heads (🌞) or Tails (🌛) — determined by a crypto-random algorithm.
- Check the tally cards below to see your running totals, percentages, and current streak.
- Use the history dots to review your last 30 flips at a glance.
- Hit 'Reset' to clear the tally and start a fresh session whenever you need.
FAQ
- Is this coin flip truly fair and random?
- Yes. Every flip uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness — not the weaker Math.random(). Each flip is an independent 50/50 event.
- Is it free to use?
- Completely free, always. No subscription, no account, no hidden fees. Just open the page and flip.
- Does it work offline?
- Yes. After the page loads once, all logic runs entirely in your browser. You can flip coins without any internet connection.
- Is my flip history private?
- Absolutely. Your tally and flip history are stored only in your browser's localStorage. Nothing is sent to any server. No tracking, no analytics on your results.
- Can I use it to settle a bet or make a quick decision?
- Absolutely. Whether you're settling a friendly bet, deciding who goes first in a game, or making a quick yes/no call, a crypto-random coin flip is as fair as it gets.
