The following metro rail lines are available: Midosuji, Tanimachi, Yotsubashi, Chuo, Sennichimae, Sakaisuji, Nagahori-Tsurumi-ryokuchi, Imazatosuji, Newtram Nanko Port Town, Kita Osaka Kyuko, Kintetsu Keihanna, Hankyu Kyoto, Hankyu Senri, Osaka Monorail, and Kitakyu Namboku lines. The maps have small file size footprints but with many levels of zoom and can work offline without connecting to the Internet. Users can click the train station box labels to open Google Maps or Google StreetView, where they can use all the functions of the Google apps to visualize the surrounding area and/or perform routing for directions. There is also an offline function to calculate the best way to travel from a station to another station with a direction breakdown and timings (which may vary from the actual travelling time).
