The most-used apps are also the most downloaded apps
With the exception of pre-loaded apps such as Safari and Apple Music, all of the apps that are most-used also feature on the most-downloaded apps list. So if you want your app to be among the most used-apps (and you’re not a core app developed by Apple or Google) then you need to eventually hit the most-downloaded charts. (Note that The Weather Channel and 360 Security don’t feature on our list of the top 30 most downloaded apps, but they are within the top 50.)
