Sales Networker allows you to track your networking interactions with your Contacts -- who introduced you to whom. You can also store notes and information about that person, for example what you discussed when you last talked, or what you want to talk about next time.
Sales Networker works with ("on top of") your iOS Contacts app, so you dont have to re-enter any of the contact details a second time.
Most of us keep ALL of our Contacts in our Contacts app, including family members, personal friends and other people we call frequently. But many of those people have nothing to do with our business, which makes for a lot of clutter when we try to use the Contacts app to support our business activities. Sales Networker lets you isolate and manage only your business-related Contacts and avoid the clutter, while still giving you full access to all the great features of the Contacts app.
