Aptoide is a download store for android apps like google play. The market has hundreds of apps ready to download.
To find a specific application, all you have to do is type the name of the search bar you want and select the version you want to download.
The page for each application contains the technical information and the user-defined description that it shares.
However, the most important thing to know before downloading is the comment and evaluation section of each application.

If you do not get a result from your search, do not forget that you can go to the 'Stores' tab and unofficially access the list of others shared.
