I agree. Refresh is a great free mobile app.

You're on your way to a coffee meeting with a new professional connection — the person who may be the key to your next job. The problem is, you realize that all you know about them is their name and job title.

You could wait outside the coffee shop and frantically find them on LinkedIn, scroll through the past few days of their tweets, and see if they've made any news lately. Or you could just check the Refresh app on your phone for a quick primer, says Wharton professor and networking expert Adam Grant, author of "Give and Take."

Grant tells talk show host Jordan Harbinger in an episode of The Art of Charm lifestyle podcast that Refresh is "a really clever way for preparing for first-time meetings." He explains:

What Refresh does is it basically aggregates everything you would ever find in a web search. And instead of having to go through all these different hits, it gives you one consolidated profile of all the information that's out there online about a person. And then you can figure out that you lived on the same street four years apart. Or you might share a common interest in a really obscure minor league sports team. And then you've got a foundation for a conversation, which then feeds into the other person being more likely to open up and actually tell you about how you could be helpful.

When you're armed with a bit of extra info, says Grant, you can skip awkward small talk about the weather and start on a more personal note.
