DustByte: Duplicate Cleaner finds what's quietly filling your iPhone & iPad: duplicate and similar photos (bursts and look-alikes included), duplicate videos, duplicate files and contacts, and piles of WhatsApp media.
Review everything side by side and clear it in a tap. Deleted items go to Recently Deleted for 30 days, so nothing is lost by accident.
Everything runs on your device. No account, no uploads, no tracking.
And no weekly paywall: pay once, keep it forever. Works on iPhone and iPad.
