Overview
The homescreen app is the main UI for the phone. It is shown as soon as the phone is unlocked and is primarily used to launch other apps. It also houses the everything.me component, which is a tool for finding and launching mobile websites and web apps.
Architecture
Components
The Homescreen App is implement as an certified packaged Web App and is installed to the phone as part of the Gaia repository. The source code for the keyboard can be found here: http://mxr.mozilla.org/gaia/source/apps/homescreen/
Everything.me is essentially a separate app which is included in the homescreen since they need to share data and be closely integrated from a UI perspective.
