Hello. I am looking for an app/software that can provide me with social media analysis.

I opened my shop's second branch last month. Business is booming but I want more. An acquaintance that I met last week in some party told me that he uses some sort of app/software for tracking his online reputation and doing comparisons against his competitors.

I don't know what kind of software this is. I'm thinking that maybe someone here (who maybe runs a business too?) is more knowledgeable about this matter.
