2. Google Now Launcher
For Android at: play.google.com
If you have an android device, Google Now Launcher should be one of the first apps you download. It comes as standard on all Google Nexus devices, but can be downloaded to any Android platform running at least 4.1 Jelly Bean. The app allows you to set ‘cards’ which will display on your Google Now page, which can contain everything from news updates to local weather reports.
