"Advanced" App Store search

I would like to search the iPhone app store in such a way that I only see results that don't offer an in-app purchase. I know that Apple offers a data feed of all the App Store's data, so in principle a service could exist that would allow this. However, having tried all the App Store search engines I know of (uQurey, AppShopper, AppAdvice, 148apps), it seems that none of them offer this kind of specific customised search.

So my question is whether there is an App Store search service that allows such specific queries as this.

Solution 1:

There is a way now: https://appapp.io/us/has_iap=false/search

(Full disclosure - I made it)

Solution 2:

In short: No, there's currently no query for that. At least, none of them are published. I doubt Apple want to display those without in-App purchases, as they make them money when people buy it.

I seriously hope someone will proof me wrong in the nearby-future, but currently there's no option available for this. I've been searching around for a while for those filter-criteria.
