Purify app - Am I using it wrong?

[Chupa Chupa]

I'm a little confused by the point of these new ad blocking apps like Purify. I bought Purify but it seems to disable just about every web site unless you whitelist it. And whitelisting seems to be an "all or none" proposition w/i a web site, unlike something like Ghostery for computer web browsers where you can whitelist necessary 3rd parties a site uses but leave the ad related servers blacklisted.

So if I have to whitelist every aspect of every site why bother? I can let Purify block ads but then it also blocks much of the functionality of the site. Or I can whitelist all the sites I visit to the same ends as-if I didn't even use Purify.

Is this correct or am I missing a setting somewhere that lets me fine tune what scrips and 3rd parties are allowed and which ones forbidden by a specific site?

My understanding is that the API doesn't allow this type of granulator control over blocking specific types of ad's instead of an all or nothing approach per URL.
