Google Play Store is a popular app store, however numerous apps are not available. These apps are known as black market apps, and they provide a wide range of paid apps that are free. These apps can be downloaded from many websites and sources. But not all of them are safe to download, and some may contain viruses or malware. It is therefore important to select only those applications that are downloaded from reputable websites.

Blackmart Alpha is an example of a black-market app that offers a huge assortment of games and software that are paid. The Google Play Store does not allow it since it violates the terms of service. However, you can install it easily by allowing downloads from unknown sources on your phone.

It can be very frustrating to purchase an app only to regret it later. The apps let you test out new features and make a decision upon that.
