How can I bulk install apps with Play Store or App-Brain?
This might be a new feature of newer versions of Android (I'm using 4.4), but I can easily mass install apps from the Play Store.

How to mass-install apps with the Play Store:


Open the Play Store
Go to My Apps
Go to All
Keep your finger pressed on an app that has not been installed yet for a second or so.
Now the play store goes into selection mode, you can simply select all the apps you want and press the "Install" button at the top when you
re done.
