・Transportation was paralyzed by accident occurrence,

and I'd like to take refuge in a hill right now.
But there is no time to look a map.

・It is possible to go home safely
if the child or the elderly person have the smartphone.

・A network can be used, but I also walk for several hours.
So the communication charge is worried a map apps.

・Even if I walk while looking a map,I'm lost.
But I have sense of direction, and there is probably a problem with
a map apps.I have sense of direction certainly.

When this apps also registers a target, a network is used.
It's necessary to prepare for an accident and finish
