Subzzz is your personal subway alarm clock - its an app that will notify you when your next stop is coming, so you don't have to worry about missing a station anymore.
first, the app will ask the user whether they want to go uptown or down town.
after that the app will ask for your current location and find its nearest subway station.
it will then show all the subway stations which will then be the destination of the user.
After that, the user have to click what subway stop they want to go.
Press Snooze, if the user wants to go to sleep or just be reminded if his or her destination is coming.
Subzzz will automatically calculate the time from its current location to its destination.
if there is some delays, it will adjust accordingly by using some of the subway station wifi signal.
