Free apps have to make their money somehow, be it through ads or through in-app purchases. That is great, and for those people who don't want to shell out money for applications it is a good model. However some of us don't like these sometimes annoying pop up ads, or ads blocking half of the screen. This is where some versions of applications (sometimes just with the added prefix "pro" ) come to play. You pay $4.99 for the app instead, and don't have these ads shoved in your face. However as some other forum members have also pointed out, some of these companies are "double dipping" - Paid apps WITH ads ... Do they really have to do this, or are they just getting greedy? What are the alternative solutions? Charging even more for the apps ? Whatever it is, I can't stand ads on TV, and I can't stand ads on my iPhone, especially if I have paid for it.
