People's Choice
The room votes on its phones.
One tap per person. You see the tally live; the room sees the result when you call it. Votes in rounds, for a night that eliminates. No app, no account — and nothing is stored: the result is on your screen at the end, and nowhere else.
You'll get a code and a QR. People scan or type the code, tap their choice, and can change it until you close the ballot. Then everyone sees the result at once.
