For instance, I made a free open-source iPad calculator app with no permissions, no ads, no in app purchases, nothing. If you search "calculator" on app store, you get garbage calculators w/ popups or big ad banners, and limited functionality. So surely this one would do well. So I did the social media thing.
Not only did I get very few downloads, but I usually can't even find my app on the app store if I search "calculator". I get apps that aren't even related before I see mine! Although I did get ~1k downloads a few weeks ago, because I think someone influential blasted it.
Anyway, app store is a shit show for discovery, but I guess sometimes you get lucky.
Here are my PAGE VIEWS for the first week or so:
