Google Maps is a web mapping service developed by Google. It offers satellite imagery, aerial photography, street maps, 360° panoramic views of streets (Street View), real-time traffic conditions, and route planning for traveling by foot, car, bicycle and air (in beta), or public transportation.
To do this, open up Google Maps, tap the menu button — represented by the three horizontal lines in the top-left corner — and tap Your places. You'll see entries for Home and Work. Put your addresses in. You can now ask Google Maps to navigate to Home or Work instead of having to enter the address.
