Rollback

Features
Read full description

Shoot together. Open tomorrow. One roll. A few friends. No preview, no retakes β€” and nobody sees a single photo until the roll is full and opens the next day. Then you open it together. HOW IT WORKS β€’ Start a roll β€” 12, 24 or 36 shots. β€’ Fill it together β€” invite up to 6 friends with one link. Everyone shoots into the same roll. β€’ It opens 6–48 hours later. You'll get a notification when it's ready. β€’ Tap the roll and watch the photos appear one by one. WHY IT FEELS DIFFERENT β€’ No preview means you stay in the moment instead of checking the screen. β€’ No retakes means the photos are real, not curated. β€’ The wait makes the opening better. Rediscover moments you'd already forgotten. MORE β€’ Gift a roll β€” send a finished roll to someone as a one-of-a-kind present. β€’ Solo rolls too β€” the same ritual, just you. β€’ Guest mode β€” try a 12-shot roll with no sign-up. β€’ Free to start. Buy more rolls when you need them.
