About

ZeroRoll

Features
Read full description

Your camera roll is a graveyard. Screenshots from 2019. Twelve near-identical shots of the same sunset. A 4K video you forgot existed, quietly eating your storage. ZeroRoll is Inbox Zero for your photos. You swipe — right to keep, left to let go — and a year of clutter clears in a few quiet minutes. Everything happens on your device. Nothing is ever uploaded. — HOW IT WORKS — • Swipe right to keep, left to delete. One photo at a time, like clearing an inbox. • Smart Stacks finds your duplicates, burst shots, and near-identical retakes, groups them, and lets you keep the best and drop the rest in one move. • One tap surfaces your screenshots, blurry photos, big videos, and social-media downloads — the easy wins, sorted for you. • A monthly timeline shows exactly where your "storage debt" is hiding. • You finish each session with a clean summary: photos triaged, space freed, and a streak to keep you coming back. — NOTHING IS DELETED BY ACCIDENT — • Left-swipes go to a staged review, not the void. You confirm before anything goes. • Final deletion uses your phone's own system dialog — the same one Apple shows — so you're always in control of the last step. • Trashed items sit in a 30-day grace window before they're permanently removed. You will not lose a photo you meant to keep. — PRIVACY, THE REAL KIND — Most "cleaner" apps quietly send your file metadata to a server, or run your photos through cloud "AI." ZeroRoll does neither. Your photos are analysed on your device and are never uploaded. No cloud processing. No analytics. No ads. No account. • Your photos never leave your phone. There is nothing to leak, nothing to sell. • Built by one independent developer who doesn't sell your data. The only thing Apple ever sees is your purchase. — FREE, AND HONEST ABOUT IT — • Free forever for your current and previous month — genuinely useful, no trial timer. • ZeroRoll Pro unlocks your entire photo history, all the way back — with a simple monthly, yearly, or one-time Lifetime unlock. • No weekly traps. No "subscribe to see results" paywall. No dark patterns. The price on the button is the price. — WHY NOT JUST USE PHOTOS? — Apple Photos shows you everything. ZeroRoll helps you decide. It does the boring part — finding the duplicates, the blur, the forgotten 4K videos — so the only thing left for you to do is swipe. Stop hoarding photos you'll never look at again. Reach Inbox Zero — quietly, safely, entirely on your own device. — SUBSCRIPTION TERMS — ZeroRoll Pro is available as an auto-renewable monthly or yearly subscription, or as a one-time Lifetime purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
