With one of the most basic features disturbingly absent from the native iOS Contacts application, Cobook fills the void with robust contact group management options. It has been updated to version 3 and it is well worth a look. It combines gesture based shortcuts, tie-ins to 3rd parts social networks and a iOS 7 look to provide an elegant and streamlined way to manage your contacts. It is a complete solution for your contact sorting needs and it is available for free with in-app purchases available to enable more awesome features. Check out Cobook today.
