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 6β48 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.

Verdict
The clearest difference is in-app purchases: Rollback at none against mojimoji's 2. Rollback also leads on iOS requirement (13.0 vs 26.0). mojimoji's advantage is update cadence (daily vs every 10 days). On price, ads and device support there is nothing between them.
