While this app does as advertised (ironic as it sounds, considering its functionality) it tends to slow down loading times which is not ideal.
Additionally, it would be nice if the developers could make a version (or add functionality in a later update) that can block ads on cellular too. (Looking at you, Adblock!)
If they find a way to make these changes, I will be more than happy to revise my review.
