What is Gapps (Google Apps)? I have some questions regarding Gapps:


What is Gapps? Is it a custom ROM?
Do I have to install it on my Android 4.4 device?
GAPPS is not a custom ROM. It means "Google Applications" and usually includes Play Store, Gmail, Google Calender, and more. If you have some of these applications, then you already have some GAPPS.

Most users will only need to install GAPPS if they have installed a custom ROM that did not have GAPPS included.
