The Apple App store in its current iteration is just mentally exhausting. Everytime I open it up I'm presented with a new grid of app icons and no context to why I should care.
To further detriment, Apple has trained the market to stay away from 3rd party curation of iOS apps in any kind of useful way. So we're left only with a gateway of lists. That's nice, but not worth my time.
Correct me if I'm wrong, but ultimately an indie game has limited replay value because they're just so small in scope, but they're usually a lot of fun. So a one time upfront payment to enjoy for a few weeks is a great business strategy I think.
Edit: Not to sound like I'm bashing Apple here, as I don't think the Google Play store does it any better.
