This program is ideal for those of use who don't want to search our (minimally organized) Address Book for the the info we can't quite dredge up for an e-mail--like the name of the person who lives across the street from one of my husband's cousins and is having a baby shower for the cousin and spouse. Luckily they all share the same area-code and city/state, and luckily I have TapDex. It's useful for more organized people and purposes too--one of those apps that makes all of us seem even more efficient than of course we are.
