PHONE-A-TAXI APPPHONE-A-TAXI is an exclusive app that may be used in the event of being stranded. With GPS technology, it would detect the nearest taxi rank or a bus service for whoever has subscribed to the service. To operate this app, one must telephone the taxi company in order to charter a taxi from the person's exact location, and send it straight to the passenger from the call by auto-detection of GPS. If you think something can be better added to my App idea feel free to tell me and I am open to all kind of suggestions.PHONE-A-TAXI APPPHONE-A-TAXI is an exclusive app that may be used in the event of being stranded.
