About Coin Flip
A quick way to make a random decision. Tap Flip for Heads or Tails, or switch to Yes/No mode for quick decisions. Everything stays on your device, and nothing is sent anywhere.
FAQ
Is this actually random?
Yes. It uses your browser's cryptographically secure random number generator, the same kind used for security-sensitive code, not a predictable pseudo-random formula.
Does it store my results?
Only in your own browser, so you can see your last 10 flips. We never see this data.
Can I use my own options instead of Heads/Tails?
Yes. Open Customize under the coin to add your own two options (like "Pizza / Tacos") and pick a coin color.
Does it work offline?
Yes, once you've loaded it once, it keeps working without an internet connection.
Can I put it on my home screen?
Yes. On iPhone, open this page in Safari, tap Share, then Add to Home Screen. On Android, open it in Chrome, tap the ⋮ menu, then Add to Home screen (or Install app). It then opens like a regular app.
