Covve syncs two-way with your phone's address book and supports contacts coming from all major contact accounts: Google Contacts, Exchange, iCloud, Outlook and Yahoo.

Covve doesn't currently support a direct import of contacts from a file. 

If you have a list of contacts in an Excel spreadsheet or a .CSV file that you want to add to Covve, you can import the file to the email account syncing with your device. 

The contacts will show up in your device's address book and will then, be synced into Covve.
