Parallel Space is a free tool for Android which allows you to run multiple accounts in one application at the same time, such as Facebook.
Most users maintain more than one account on a social network, such as Twitter or Facebook, or have multiple Gmail accounts. Although we are not concerned with the reasons that each user takes such actions, at least in this article, we are concerned that most applications for Android do not allow two instances of the same application to run simultaneously on the same mobile device.
You should log out of an account in an application and then log in to the same application with another account. This process is very disturbing to most users.
In fact, and especially for social media, not even one desktop with computer you can be logged into two accounts in the same application (excluding Gmail) at the same time. But this scope is easily overcome for desktop computers since you can connect with different browsers to different accounts for the same social network. In smartphones where surfing through broswer is not the best, companies have made special applications for Android that run only one social network, for example Facebook.
If you want to run multiple accounts in the same app at the same time, there are many tools that can help you. Typically these create a separate space or virtual environment to run the same application one more time, at the same time, on the same device.
