Remember when the invigilator shouted "pens down!"? I turned that into a quiz app.

That exact moment — pens hitting the desk at once, everyone caught mid-thought — is the whole idea behind PenDown, a live quiz app I just built and shipped.

🔗 Try it: https://pendown.live

How it works

Someone hosts a quiz (or just launches the built-in demo — takes 5 seconds)

Everyone else joins from their phone with a 6-character code — no signup, no app to install

Questions come in live with a countdown

When time's up, every screen gets stamped: PEN DOWN!

Live leaderboard after every question, final results at the end

It's built for the exact moment you'd actually use it — a college quiz night, a team icebreaker, a family group chat challenge, killing time with friends.

Why I'm posting this here

I want strangers to break it before real users do. Friends are too nice when they test things. So:

Grab a friend, coworker, or literally anyone in a group chat and play a round together (it's way more fun with 2+ people)

Try the demo quiz if you just want to poke around solo

Tell me what felt off, slow, confusing, or just didn't land

Genuinely curious whether the nostalgia hook lands for people who didn't grow up with the same "pens down" moment, too — would love to hear if this feels universal or very specifically an Indian-exam-hall thing.

https://pendown.live — go make some noise.
