Shapr
Shapr is a new, mobile-only, way to find the right people to network with. Like a matchmaker for professional relationships, their goal is to make it easy for you to grow who you know, accelerate serendipity, and make the connections you need-- through the people you trust. Instead of swimming through a sea of online contacts, or asking for email introductions, users share vetted contacts with others in their network.
Namerick
Nothing will be more humiliating than not remembering someone's name right after meeting them or upon repeatedly running into them. Thankfully, there is an excellent application to resolve this issue: Namerick. The application allows you to quickly record a name and write down notes concerning that person, like what they are wearing, when and where you initially met, and additional identifiers. You may browse names and notes to remember names, as well.
