It is an android app.It will fetch your location and show in on defaut map.It will also display your address
At first time your app will get crashed. dont worry. close app and go to settings and give permission to app manually.
settings->apps->whereiam->tick permission
to get location,your net connection and gps should be on.
sometimes you may not get your location when you have poor connection.
to access this app you should have powerful net.
enjoy.....
