Every memory. One timeline. Gathered from everyone, cherished forever. Eterna turns your wedding, birthday, or celebration into one shared photo album that everyone helps create. Instead of chasing photos from a dozen phones after the event, your guests capture the moments live and they all land in the same place. SAME HEART, DIFFERENT VIEW Every guest sees the day from their own angle. Eterna brings all of those perspectives into one shared memory, so you never miss the moments you couldn't be in. SEND THE LINK, ENJOY TOGETHER Create an album, share a QR code or invite link, and your people are in. No accounts to chase, no group chats to dig through. Everyone captures into the same film roll, from everyone, in one place. THE MAGIC OF DEVELOPING Like a disposable camera, photos don't appear instantly. They stay hidden and "develop" after a delay you choose. The result is a beautiful surprise when the album reveals itself, the way real film used to feel. ONLY INVITED GUESTS CAN ENTER Eterna is a private space. Only people with your invitation link or code can join and contribute. Your memories stay with the people who matter most. HOW IT WORKS 1. Create your album. Name it, set how long it stays open, and choose your develop delay. 2. Invite your people with a QR code or shareable link. 3. Everyone captures together using the in-app camera. 4. Watch the photos develop, then view and download your favorites. FEATURES - Shared event album that everyone contributes to - In-app camera with flash, zoom, and front/back flip - QR code and invite link to bring guests in seconds - Develop delay that reveals photos like real film - Open window so capturing closes automatically after the event - Contributor names on every photo, so you know who caught the shot - Private and invite-only by design - Choose who can view: everyone or just you - Download single photos or the whole album to your device PERFECT FOR - Weddings and engagements - Birthdays and milestone celebrations - Parties, reunions, and trips - Any moment you want to remember from every angle PRIVATE & SECURE Your album is only open to people you invite. Your precious memories remain untouched, private, and entirely yours. Start your first album and let everyone capture the moment together.

Get your storage back. Keep every memory. Doppelgone finds the duplicate and lookalike photos filling up your iPhone (exact copies, bursts, retakes and photos saved twice from chats) and keeps the best shot of each: eyes open, sharp, well lit. HOW IT WORKS • Scan: Doppelgone looks through your photos right on your iPhone. Nothing is changed. • Review: every set shows which photo stays. Tap any photo to keep it too. • Clean up: only what you approve moves to Recently Deleted in Photos, where it stays for 30 days. PRIVATE BY DESIGN • Your photos are analysed on your iPhone and never uploaded. • No account, no sign-up, no ads. • Doppelgone never deletes anything permanently and never touches photos you didn't approve. FAST • Uses the Neural Engine in your iPhone to compare thousands of photos in minutes. • Finds exact copies, near-copies (edited, resized, re-saved), bursts and similar shots. FREE AND PRO • Clean 200 photos free. • Pro is one purchase, no subscription: unlimited clean-ups on this iPhone. Questions? support@doppelgone.app Ā· doppelgone.app
