Koestr hands each guest a personal deck of photo & video challenges from a single QR scan — no app to install — then streams their best moments onto a big-screen live wall in real time.
See the guest app →No sign-up, no download. A guest scans, plays, and follows the whole event from a simple tab bar.
A first name is all it takes — no account, no password.
Photo, video, hunt & prompt challenges, each worth points.
Active challenges, event progress, and the top contributor.
Point a projector at the wall URL. It opens on the couple's branding, shows a scannable join code while it's quiet, then rolls into a live mosaic of approved moments — no refresh.
A branded welcome sign and a QR table card for every table — laid out and ready for the printer, kept crisp and white so they read across the room.
Every challenge scores; the ranking updates as captures land.
Risky uploads are auto-held so nothing hits the wall the couple wouldn't want.
A signed guest token — no passwords, just a first name that credits every moment.
Captures queue on-device and upload themselves when the signal returns.
Every event gets its own branding, guests, and wall on one deployment.
Wall, stats and leaderboard sync live, with a polling fallback.
