Screenshot shows Inside Maps website not the app itself
Have you ever been frustrated that Google Maps doesn't have indoor maps for shopping malls and airports? If so then you need to download (for free) Inside Maps for your iPhone or Android phone.
When you open Inside Maps on your mobile phone you are presented with a Google Map with markers showing the Inside Maps available for malls and airports near your current location. If you select one of the markers you can then download the Inside Map for the chosen mall or airport.
All the maps are produced by Inside Maps themselves and are interactive and searchable.
