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.

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
