Is there an app/portal which allows a user to navigate across different apps across App stores by concept/functionality like Reading app, Travel app etc. Once I select a reading app say Book reading it then shows me all the top performing app (across app stores, countries, language etc).
I should be able to compare their functionality, How their concept differ from each other?, What is their market share?, Which markets/countries they serve?, What is their core revenue model etc?
OR this is too much to ask?
