Contacts BU saves all your contacts as a standard vCard (.vcf) file on your iPhone, lets you look inside any backup, put back contacts you deleted, and export a backup anywhere you like.
Download on the App StoreBack Up Now saves every contact (names, phone numbers, emails, addresses, birthdays, websites and photos) to a .vcf file on your iPhone.
Open any backup to see and search the contacts in it.
Restore lists the contacts in a backup that aren't in your Contacts anymore and adds them back after you confirm. It never deletes or overwrites anything.
Share a backup to Files, iCloud Drive, AirDrop or email. Any vCard opens in Contacts on iPhone, Mac, Android and most email apps.
Bring in a vCard file from an old phone or another app, look through it, and restore what's missing.
Contacts Backup Pro makes a new backup when you open the app and your last one is older than a day, a week or a month, your choice.
