I hate the fact the both Apple's App Store as well as Google's Play Store do not offer basic search filters. In particular for my kids, I'd love to be able to search for games without ads or in-app purchases. But Apple and Google do not offer this feature because it would hurt their revenues. That's why I'd love to have a good alternative to the App Store or Play Store.
