Show HN: WordsUnite – Synchronized Crowd Chants at Scale

I built this app because I've always wanted to know what a synchronized crowd would sound like beyond stadium size. The app is privacy-focused (no tracking, no ads, no hidden pixels, minimal information used). Only an organizer needs an account, all participants join via QR code with no data collection. If you're interested in testing in a large group, send a message to the support email and I'll send free codes.
