u can call it a safety or an emergency app. this app tracks your current position and fetches your exact address as soon as you click on its icon . just one more click on the exclamatory triangle button and you can send a 'i m in trouble' msg to your dearest person . just set a number from menu 3-dot button when u install the app for the first time.the app gets your longitude and latitude location without internet and then may track your exact address with limited internet.
as a well wisher i hope you never find a need to use it :D. but to be concerned u shud have this :p.
