You know how these apps work. Sometimes, it is all about advertising and how "noisy" the company is. Take for example, ads on television. Right now, the "noisiest" here in IL is bosley. However, when you go online and check some bosley reviews, there are a lot of customers giving them reviews. Some were happy and some were not. The point is, people go to them or in the case of apps, "use" them because they are popular or "noisy." know what I mean?
