ContactsDuster is one of the original iPhone contacts cleanup apps, helping people dust messy address books since 2010. Redesigned in SwiftUI with a fresh Liquid Glass feel, ContactsDuster keeps contact cleanup simple: find duplicates, merge repeated people, remove empty zombie contacts, organize groups, and keep a backup ready when you need it. Why people use ContactsDuster: - Clean duplicate contacts quickly - Merge matching names, phone numbers, and email addresses - Remove empty or incomplete zombie contacts - Organize contact groups - Export contacts as vCard - Back up and restore with backup history in your iCloud account ContactsDuster works directly with your iPhone and iPad contacts. Your address book stays yours: contacts are not uploaded to us, and backup history is saved in your own iCloud account so we do not have access to it.
