iPhone
Wednesday is Civil War day: one question, two sides, and the screen splits down the middle. Pick yours.
Seven questions a day. Everybody gets the same seven.
You answer first. Then you do the harder part: guess what percentage of everyone else answered the way you did. At 21:00 the curtain lifts and you find out how well you actually know people.
Most of the time you are wrong. That is the whole point.
HOW A DAY WORKS
1. Seven questions land at midnight. Ordinary things — how you hang the toilet roll, whether you rinse pasta, what you would do with a wallet you found.
2. You answer, then predict the split.
3. Answers lock. No take-backs, no editing, no seeing anyone else's first.
4. At 21:00 the real numbers arrive, for your region and for the world.
WEDNESDAY IS CIVIL WAR DAY
One question a week is chosen because it splits people close to fifty-fifty and neither side can believe the other exists. The screen divides down the middle and choosing an option means joining a side. You get a team name. If you end up on the smaller side you get called a Resistor, which is the better badge.
WHAT YOU FIND OUT ABOUT YOURSELF
Two numbers follow you. How well you read a room — the gap between your guesses and the real splits. And how unusual you are — how often you land where almost nobody else did. They build into a picture of you over time that is uncomfortably accurate.
DUO
Pair with one person. Instead of guessing the world, you guess each other. It turns out to be a very fast way to find out whether someone has been paying attention.
ROOMS
Bring a group into the same question and watch the room split in front of you.
THE QUIETER QUESTIONS
Some days go deeper — what you would forgive, what you have never admitted, what you would do differently. Those answers are never shown next to your name, on any card, to anyone. The question is hidden on shares too. The rule is in the security rules, not in a promise.
WHY IT IS THE SAME SEVEN FOR EVERYONE
Because a number only means something if everyone answered the same thing on the same day. There is no feed, no infinite scroll, nothing to catch up on. Seven questions, one reveal, done.
Available in 24 languages.
