Cardbook has been a life saver after our previously used Google sync app didn't keep up with TBird changes. Then we ran in to a date sync issue affecting two of several devices. The developer with excellent communications and effort found a bug that was affecting a limited number of devices. CardBook and Philippe V. are The Best!
