The main thing in this app is a double map where two different types of maps appear on one screen. If you have a big screen like an iPad, you can see its features well, but you can also use it with an iPhone. To use it, use some buttons and a pinch to pinch the screen with your fingers to check the detailed location of the destination on the map and show the surrounding situation on another map. As an example, I checked the location near Osaka Castle in Japan, and on another map, there is a screenshot showing Osaka Castle in the vicinity and the surrounding rivers. You can use it for various purposes, such as seeing what the surroundings of the destination look like, and seeing where the road ends. Please use it with some ingenuity.
