Survival Toolkit is a multi-tool APP thought to survive in remote environments away from civilization and to ease the return to it. It not only reveals the latitude and the longitude where you are and gives GPS information of your current whereabouts but also it has a compass and a built-in rescue whistle as well as a low power consumption screen-torchlight.
With this APP, to explore unknown places it will be easier than ever. Thanks to it you will never be lost.

NOTE: The compass function will only work with devices which have the orientation sensor.
