Google Earth app its my review is average app. There are two Google Earth app one is use totly free and second is buy $399. I am useing free Google Earth aap is very slow loading map to compare with Google map. Google Earth have some interesting features just like use 3d view and street view but some also have disadvantages like u don’t have go to one place to another place step by step road travel view and information. And also its functions is so complicated it is not use simple way. It is not useful in emergency time.
