Simple and intuitive operation GPS navigation iOS app. It is the concept of SkyWalking.

Such as mountain climbing, trail running, even in the mountainous area that can not be connected to the net, if in advance to create the offline map data, display the current position and altitude without having to worry about the network connection, you can display your present location, altitude, direction, route and destination on the map.

SkyWalking, by overlay display the tile image on top of the base map, you can take advantage of the map from a new perspective.
For example, by overlaying the aerial image of the 1950s, and bird's-eye view of the previous situation, it can be compared to the current map. By overlaying the aerial images taken at the time of eruption or disaster occurs, you can increase the knowledge on disaster prevention.

Get your act as a GPS log, can be displayed on the map in real time. To share friends and GPS logs exported to GPX format, it can also be displayed on the map to import GPX of other people to SkyWalking. It helps prevent distress and road hesitation in climbing.

It corresponds to FlyOver that has become available since iOS 9. Popular cities such as Tokyo, New York or such as the European Alps or Yosemite National Park, let's try the bird's-eye view of the attractions in the Sky mode. You can enjoy a sense of realism, such as was the bird.

For in GPS logging app continues to operate GPS is also in the background, so you consume the battery, please note.
