what I miss in this discussion is whether more user reviews indeed lead to more sales?
Good point, I think the answer is yes (provided the average rating is 4 stars or better of course). Users are more inclined to look at an app when it has many good ratings, for example "57 users reviews avg. 4,5 stars". This average stars-rating of an app is shown in the AppStore app on search results and other "overview" pages (top 25, new apps, category etc). But it is displayed to the user only when there are 5 or more ratings for that country
, else it just shows "no ratings". So for example, I just saw that my app has 1 German review (thanks Kitty
, I overlooked it earlier), so the 5 stars are not shown to German appstore users, unless they open my app's page and click ratings.
And again, I think the "Move The Box" app is proof that more ratings lead to more download (which in turn leads to more ratings, like a feed-back-loop). One of the first things users see is the amount of user ratings, and this immediately gives them the impression that it is a popular app, simply because 15.000 review equals at least 15.000 users; It's been hovering in the top downloads for more than a week now.
@ampos: nice going
but I think you can only tell in about a week, when most users have updated your app.
