Contacts Backup & Manager 2.1

This application offers a function to eliminate duplicate contacts within a group. It identifies contacts with similar phone numbers and consolidates them into a single entry. Moreover, it identifies contacts with duplicate phone numbers, emails, websites, etc., and provides the option to either remove the duplicates or merge them into one unified contact.

Another notable feature of this application is its effortless method for backing up and restoring contacts directly from your phone without the necessity of a computer or synchronization process. With just a single tap, you can back up all your contacts and conveniently send them to yourself as a .vcf attachment via AirDrop.
