I´m looking for an app that can give me alert of proximity for some points when i´m navigate, like warning of crossroads, places to eat and drink, etc... maybe something like we choose some points and define a distance, and when the distance to the point is smaller than the defined the gps send a alarm and the name of the point pop up on the screen.
I´m not finding it and i don´t known how to start it...
Many thanks
