Capture and share memories from every angle! Snap Eighteen blends the nostalgic magic of a disposable camera with the convenience of a modern, shared photo album. Everyone at your event snaps from their own phone, and every shot lands in one live album. No more begging friends to text you their photos the next morning. EIGHTEEN SNAPS. MAKE THEM COUNT. Like a disposable camera, each guest gets 18 snaps per event, so the album fills with real moments instead of retakes. Hold the shutter to record video. Prefer one big pot? Switch on a shared snap pool for the whole party. INVITE IN SECONDS Create an event, then share its QR code or link. Guests scan and they're in, even without the app: they can join from their phone's browser, snap, and see the album. Print posters, table cards or tent cards for the venue straight from the app. ONE LIVE ALBUM Watch the album fill in real time, react to snaps and leave comments. You decide when guests see the photos: live, when the event ends, or later with Pro. Guests can leave you a voice message of up to a minute, even if they couldn't make it. PUT IT ON THE BIG SCREEN The Live wall turns any TV or projector into a slideshow of the newest snaps, with a QR code so more guests can join. FIND YOUR SNAPS Take a quick selfie and Find my snaps shows only the photos you're in. The matching happens entirely on your phone; nothing about your face is stored or sent. HOSTING MADE EASY Make a guest your co-host, approve snaps before they appear, and hide your event from friends' feeds. Let guests add photos from their camera roll after the party ends. RELIVE THE NIGHT Pick your favourite snaps for a photo recap to share in one tap, or turn the night into a video with music for Stories or the feed with Pro. Download the whole album to Files or straight to Google Drive. WORKS WHEN THE SIGNAL DOESN'T No signal at the venue? Keep snapping. Snaps, new events and edits are saved on your phone and sent as soon as you're back online, even with the screen locked. FREE OR PRO Free events take up to 18 guests, run up to 48 hours and keep their snaps for 30 days. Need more? Buy a size for a single event, or go Pro for events of up to a month and 1,000 guests, snaps kept for a year, every reveal option, bigger snap pools, longer late uploads, video recaps and a web gallery with no time limit.
