Hi and Welcome to the Community!
It is the app developer who decides the specific BB models/major OS levels that they will support. There is a very large combination of those two factors, so most developers choose only to support a subset of the total. But, again, it is the developers decision concerning that.
BlackBerry receives app submissions from developers...but only rarely does BlackBerry solicit anything from the developer community. Hence, the best place to seek an answer to your question is the app developer. If you have the app somewhere else or can otherwise find it in AppWorld, perhaps it has contact information for them that you can use to make your inquiry.
