A lot or a little?
Parents need to know that Google Maps is essentially a map and navigation tool based on Google Earth with some very cool bells and whistles. Along with map layers like traffic and Wikipedia, nearby services, and friend mapping, there's also solid navigation for driving, walking, riding the bus, or bicycling. Main menu button is not always available so moving around can get tricky. Check In and Latitude features could make big vacation-style family reunions a breeze. Please note that this review is based on the Android version of the app; the iOS version is similar but there are differences in functionality.
