I purchased this app today after testing a bunch of them. I like how the filters, labels, auto rating, and smart filters features work together. If you have a lot of feeds then it may take a little time up front to configure those four things to take "full" advantage of them. However, once you do that you will see how this app outshines the others and does the best job of organizing the feeds and providing view options that boil the information of interest to the top.
There are many features with this app, you have the option to be in total control of what is going on and how to manipulate the data.
In my opinion the only negative thing I can say about this application that documentation needs to be expanded. I expressed this to the developer and he very quickly responded and advised they are currently in the process of providing additional documentation.
If you try this app take the time to understand all of the features and how nicely the the label, filter, auto rating, and smart filters can work together to present the the feeds in a very efficient and effective manner. Even thought there are some free alternatives I felt that unique features, stability, speed, responsiveness of the development team regarding questions, and logical workflow all made this product worth $30.
