The iTunes App Store is filled with a ton of reviews written by people just like you or me. Except the ones that aren't, and are either paid for, spammed or aggressively requested. AppRecs seeks to filter out those junk reviews. When you search for an app title in AppRecs, it runs through the text of reviews to filter out the least trustworthy posts. These tend to be reviews where the app constantly asks people to write reviews or when reviews are reward driven, paid or just obviously biased based on a person's other reviews. If you curious about how AppRecs figures this out, they detail their process here. It is not a perfect system and AppRecs is still sure to miss some scummy reviews, but it does make cutting through the crap reviews in the iTunes App Store a little easier.
