Hangs on add contacts – Grocery Shopping List by Capitan Review

Looks like it would be a good list app but won't add contacts it just hangs and won't show my wife in the list when it does show up. I don't use Facebook so maybe that is why? Pretty much useless to me if I can't sync with my wife. Update has same issue with sharing.
