No better app for Earth Day than Google Earth

by Kate Currin

The best way for Android owners to honor Earth Day 2011 is by downloading the classic Google Earth app.

Of course, the Google Earth app is still good for its original functions, like exploring vacation destinations before you get there to find the hotel closest to the hottest restaurants and with the shortest walk to the beach. Or, simply use it to stalk your old acquaintances. The handy voice search allows you to speak where you want to go, which is great for teaching geography to young children. Little Jimmy doesn't know where Dubai is? Let's ask the Google Earth app where it is.

Literally fly across the world with the swipe of a finger. This app is an amazing way to travel without shelling out a dime.

Android 2.2 users can also benefit from installing flash in order to use Google Earth's new balloon functions – great for watching videos in app.
