Comparison
ZeroRoll vs Slidebox
Slidebox is a long-running, well-liked swipe-to-organize photo app — you flick photos into albums and clear the rest, and it can sync or back up to Dropbox. ZeroRoll plays the same swipe game with a stricter privacy stance: 100% on-device, nothing uploaded, every delete reversible for 30 days, and a one-time lifetime option.

How to choose
If you want your library mirrored to Dropbox and you’re organizing into albums, Slidebox is a solid, established choice. If your priority is cleaning up and reclaiming space without anything leaving your phone — with automatic grouping of bursts and near-duplicates, a 30-day undo on every delete, and the option to pay once instead of subscribing — that’s exactly what ZeroRoll is built for, on iPhone and Android.
