As Applanet, Blackmart is one of the best stores to download Android apps for free. Although the discharge is usually slower than in Applanet, downloads are usually more stable.
Blackmart Alpha allows you to download for free any payment application that is available on its servers. This has an excellent user interface that lets you search and find applications. Also the store is in Spanish language so that navigation within it will be much more comfortable.
Applanet continues to have more applications, however, Blackmart has nothing to envy. As the official Google application Play, automatic installation is included, so you just have to put you to download the application and then you can use it.
Blackmart also has filters that allows you to sort applications by name, size, price, date and value and offers the possibility to uninstall applications and make a backup of them.
