Annoying popup windows

I rarely if ever write reviews of apps.
This one, however, really irritates the crap out of me.
I purchased the "premium" version to get full content and no ads.
What I get in return are popup windows pushing their multiple other apps, and to "like" them on Facebook or twitter, etc.
Incredibly juvenile and annoying.
The app would have rated higher, it is enjoyable, but for this.
I would encourage folks to NOT buy this app until they remove the advertising crap….
