One camera for the moment.
The Roll replaces sending photos back and forth after every trip and event. Start a Roll, share one link or a QR code, and everyone who joins shoots into one shared album from their own phone: tap for a photo, hold for an 8-second clip. No app or account needed to shoot. Nothing gets sent around, and everyone in the album gets the whole thing.
The album is live by default, so the room watches it fill. For a party, flip one switch to seal it: nobody scrolls while the night happens, then it develops at a time you promise and every phone buzzes at once. For a trip, leave it open and the film reloads daily.
As soon as the album is ready, an AI editor cuts it into captioned vertical videos, one for every guest. Post one together, from all accounts at once. Every album lives in Memories in the app.
Joining takes one tap on one sentence: everything shot on this Roll belongs to everyone on it. Anyone can hide any capture of themselves at any time.
