MCBackup - My Contact Backup is an iPhone app developed by Ravi Kotadiya for backing up contacts on your phone without syncing to any server or needing a computer. With just two taps, you can back up all your contacts and send them to yourself as a .vcf or .csv file. Moreover, you can easily delete and merge duplicate contacts, remove contacts without names or phone numbers, and filter contacts by recently added, job title, birthday wise, and more.

One of the best features of MCBackup is the ability to find and merge duplicate contacts, including duplicate phones, duplicate emails, and similar names. You can also easily restore vCard with multiple selections and share backup files in 10 different languages.

It's important to note that MCBackup offers offline backup, ensuring that your contacts are safe and secure without the need to sync to any server. The app is completely free and offers an intuitive and user-friendly interface that makes it easy to back up and manage your contacts.
