I love this app! All your contacts data in one location, drag and drop for files, app prompts you to add new contacts and maps them. Has a logs (notes) section, to do lists for each contact and can add to do lists to your calendar for you! For me personally, this app takes the place of 2 apps and eliminates customer files that are on my computer. Export and import features are so easy to use… Its simple, its fast and I dont see how it can get any better. Very well done!!!
