andoird and apple application - project HWY

Basically, A user loads the software and logs in with a simple car registration/user/pass/email registration. Once logged in gps is to take your location and other users logged in can see the users car registration or username (can be optional to show) and also their co ordinates where they have logged in just when the log in. There is to be a refresh option where user can press refresh and the map will update their location so everyone can see where they are located and the old location is removed. and logout will remove user from the list of logged in users but a log will be available for 24 hours to show they had been logged in. Also registered users can msg them selves live or leave off line messages via text. Also another tab/page where it is a live feed of a facebook page/group that will be created. If possible to allow the user to be logged in even with program closed. Only to disconnect the user when they log off. If they user has not logged of for 30 mins, they will auto be logged off. This is most of the project and maybe some slight additions/modifications along the way. Nothing hard but would like it to look a little fancy and be FAST without all the bloatware.
