What you probably want is to ask about relevance.
[Information]. Is this relevant to inclusion in the OtherCompany AppStore?
It's a phrase that is more suited to a formal register than an informal one, and it's asking if the information is in any way of interest as regards inclusion in the AppStore in question.
Your original version doesn't seem informal, however, as much as it is subtly 'wrong' to native eyes/ears. Making a difference for inclusion just doesn't work, though I can't put my finger on why.
However you phrase it, you might potentially be better of specifically asking about the inclusion of this app itself - assuming you are talking about a specific app. If it's a component you are trying to market to app authors, you might specify that you are referring to the inclusion of apps that make use of it. So that could be:
Is this relevant to possible inclusion of [name of app] in the OtherCompany AppStore?
Is this relevant to inclusion of apps that make use of [name of component] in the OtherCompany AppStore?
