Mobile Metro Guide contains a minimap of the city with two levels of zoom, an exhaustive list of metro stations grouped on lines and a list of the most important 15-20 attractions marked on map. The application includes a route planner for metro trips. Because all the data are stored in the terminal there is no need for a GPRS or GSM connection in order to use Mobile Metro Guide. It can be used anywhere anytime disregarding the signal strength or roaming availability.
