Questions & Answers

1. What's the story behind klapp?

   klapp is made in Bergen, Norway, by Cadence AS, and has been open at playklapp.com since 12 September 2026. It started from two ideas about live quizzes in rooms: nobody should have to write the questions, and points for speed reward reflexes rather than knowledge and make a room tense instead of alive. So the product was built the other way round. The host types a topic and reads the round that comes back; the players answer on their phones and say how sure they were; the clock makes the drama but never scores. Everything else, from the six-digit code to the big-screen view, exists to keep the room looking at each other and not at a leaderboard.

2. What makes klapp unique?

   Three things, and they hold in every game, not in a mode you switch on:

   • No points for speed. After picking an answer, the player says how sure they are. A correct answer scores for every step of sureness, a wrong one costs. Answering fast is worth nothing, so the room thinks instead of racing.
   • Nobody writes the questions. The host types a topic, pastes text or hands over a slide deck, reads the round before anyone plays, and drops what they would not defend out loud. There is no library to build.
   • Nothing to install, no account for anyone. Players join with a six-digit code in the browser. Hosting and playing are free, and the size of the room is never the price.

3. Why should a person choose klapp over its competitors?

   Choose klapp when the room matters more than the leaderboard. Points come from how sure you were, never from how fast you tapped, so the quiet people who actually know things win as often as the quick ones. There is no quiz library to build or maintain: a typed topic, pasted text or an uploaded document becomes a round in a minute or two, and the host reads it first. Nobody in the room needs an app or an account, and there is no cap on how many can join. Hosting and playing are free today, with no card field anywhere. If what you need is a question bank, analytics or a study mode, other tools do that better; klapp is for the live moment in front of a room.

4. How would you describe the primary audience of klapp?

   Whoever has to stand in front of a room and make it come alive: the colleague who runs the Friday wrap-up, a teacher with a class and no time to write questions, a presenter who wants a live round inside a talk, and the person hosting a party or a Christmas dinner. klapp is made in Norway and has a Norwegian front page and a weekly Friday quiz on the week's news, but the product is in English and works anywhere a browser does.

5. Which are the primary technologies used for building klapp?

   klapp runs entirely in the browser, for the host, the players and the big screen alike. The three views are connected to one game over a real-time WebSocket connection and share one clock, so an answer registered on a phone shows up on the big screen at once. A load test on the live server put 10,240 synthetic clients in one game: all 10,240 answers registered, none lost, at 65 percent of half a CPU core (13 September 2026; scripted WebSocket clients, not people). Hosting is in Azure, Norway East.
