Ann: 2016 Financial Report, page-52

That's not the point of my post couch. The Rova can't be sold until the apps are available. There are listed companies who make a big deal about having their apps available.
Didn't at all suggest anything to do with cost at all, in fact my understanding is that both Android and Apple are added to the respective sites at no cost, but of course they need to test beforehand. But being in the game, you'd have known that.
