If your app, does not send information in two or more directions, as in, it only downloads some information. Then it is NOT a sync app, it is an IMPORT app. , please learn the English language. Merely downloading some information from Facebook for a preexisting contact, or downloading a complete contact, this is called importing. The word sync is short for synchronize, which means to make two or more things match exactly.  That is not what most of the “sync” apps on the iTunes app store do.  Please do not use the word sync, unless that’s what it actually does, otherwise it is false advertising in your app name. Ok? It’s really THAT simple.
