When the deciding is the hard part
Some decisions are hard because the options differ. Most are hard because they don't. You have weighed both sides, they came out level, and now you are spending your afternoon on a choice whose outcome barely matters. That is the moment a coin earns its keep — not because chance is wise, but because it ends the loop.
This is a coin flip you can't accidentally cheat. The answer comes from your operating system's cryptographic entropy pool through the Web Crypto API, the same source your browser uses for encryption keys. There is no pattern to learn, no seed to nudge, and no way to re-flip until you like the answer — well, you can, but the running tally underneath will remember that you did.
Three ways to ask
Yes or no. The default. Two outcomes, fifty-fifty, nothing to configure.
Add a maybe. Turn on the third option when "not now" is a legitimate answer. Useful for questions about timing rather than substance: not should I, but should I today.
Your own options. Replace the answers with anything you like — two restaurants, four chores, the names of everyone who could take the bins out. The tally keeps score across the session, which is how you discover that the same person has been picked three evenings in a row.
Yes or no fortune telling: a coin flip instead of a magic 8 ball
Plenty of people arrive here not for a coin flip but for a bit of fortune telling: to ask something outside themselves for a yes or a no and get back an answer they had no hand in. The gesture is the same as shaking a magic 8 ball or spinning a yes or no wheel. What differs is the answer. The 8 ball replies with one of twenty phrases written long before you asked, and half of them are deliberately non-committal. Here the outcome is exactly one of two, and it comes from a real source of randomness rather than from a list somebody drafted in advance.
This works not because chance knows anything about the future, but because an answer from outside removes the obligation to choose and then shows you your own reaction to it. Relieved by what came up? You wanted that before the flip. Disappointed? Even more so. In that sense a yes or no flip is more honest than a horoscope: it promises nothing, it does not pretend to knowledge, and it ends the argument you were having with yourself.
The tally is the interesting part
Every flip is counted, and the count is what turns a toy into something you can reason about. After twenty flips you will almost certainly not see ten and ten, and that surprises people. Randomness has no memory and no obligation to even out on any schedule you care about; a 13–7 split in twenty flips is unremarkable. Watching your own numbers refuse to balance is a better statistics lesson than any explanation.
The tally lives in the page and disappears when you leave. Nothing is sent anywhere, because the flip happens entirely on your device — there is no server call when you press the button.
When a coin flip is the wrong tool
Chance is the right answer when the options are genuinely equivalent and the cost of deciding exceeds the cost of deciding wrongly. It is the wrong answer when you are using it to avoid responsibility for a choice you already know how to make. If the coin lands on the option that makes your stomach drop, that reaction is information, and it is worth more than the flip. Take the answer as permission to notice what you actually wanted.

Frequently asked questions
Is the coin flip actually fifty-fifty?
Yes. The answer is drawn from your operating system cryptographic entropy pool through the Web Crypto API, with rejection sampling so no outcome gets a rounding advantage. There is no bias toward yes, and no pattern to learn.
Why did it say yes five times in a row?
Because that is what independent events look like. A run of five has roughly a one in sixteen chance of appearing in any given stretch of flips, so across a session you should expect to see one. Real randomness clusters; an evenly alternating sequence would be the suspicious result.
Can I use my own options instead of yes and no?
Yes. Replace the answers with anything — two places to eat, four people who could do the washing up. The session tally then counts how often each option came up.
Do you see my question?
We never see anything. You never type the question, and the flip happens on your device with no server call, so there is nothing for us to receive or store.
What does the maybe option change?
It adds a third outcome, so each answer has a one in three chance instead of one in two. Use it for questions where "not yet" is a real answer rather than a dodge.
Can I use this to settle a bet or a prize draw?
For a friendly bet, yes. For anything with a prize, no — a flip in your own browser leaves no evidence, so the other side has only your word for it. The protected giveaway records the result on the server and gives you a link anyone can verify.
Is this yes or no fortune telling, or a generator?
Technically it is a random answer generator; the way people actually use it is closer to fortune telling. We do not pretend the coin knows anything — it returns one of two outcomes with equal odds. Set against a magic 8 ball, the difference is honesty of wording: the ball answers with a ready-made phrase from a list written in advance, while here you can see the mechanism itself and the tally of every flip in the session.
