It's very easy to navigate, configure, very self-explanatory. It does exactly what I want it to do: block those nuisance ( though necessary ads, which subsidize free online mobile surfing ) . I also block URL's and whitelist others. The team who developed this app deserve congrats for helping us mere mortals cut down on those fricking ads/ cookies/URL's/etc. Keep up the excellent work everyone. A new user/ fan in Texas.
