Back in mid-December 2015, DxO Labs released an app called "DxO Optics Pro for Photos". That's right, it's a photo-enhancement app that works with your Photos library, or something like that.
This was Version 1.0. It was soon top left on the "Best New Apps" section of the App Store's "Featured" screen, even though "We have not received enough ratings to display an average for the current version of this application." Which led me to wonder how this app could be considered "best".
How did this work, if not paid placement? Someone at the Fruit Company was looking at what just escaped from review and said "hey, that's really cool, let's feature it"? Number of installations per recent unit time?
