Has anyone on HN actually bought this application? It seems to have no reviews or ratings for any version, which is somewhat strange for something costing so much (that price motivating feedback). Even the basic version has no ratings or reviews (sorry the US basic version has 9 ratings, but no reviews).

It even includes a rating shortcut in the app itself.

I actually flagged this story when it first appeared because it seemed to be spam, and what I suspected was a fictional narrative to pitch it. e.g. a nice chart isn't necessarily backed by non-fictional numbers, but can as easily be manufactured numbers to fit the narrative.

I appreciate that I am being horribly cynical, but such is the nature of promotion today -- the story that gets you some attention often needs to be propped by a fiction about attention. I have no idea if that is the case here, but some of the signs are there.
