It's well known that discoverability and search isn't very good at the app stores that Apple and Google have.
I wonder if somebody have scraped the information from the app store webpages and used that to build an alternative interface? Hopefully with more advanced features and better discoverability? (It's fine if the site direct back to the original store page for the actual installation.)
Please note that I'm not asking for alternatives such as apkmirror.com or f-droid.org. They have a different focus and software library from the official stores. I want the apps from the official stores, just better presented.
