About

Rollback

Features
Read full description

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