Taxi Magic is the best taxi cab app for iPhone and Android. It locates the taxis that are closest to you within seconds. You can also track how long it will take your taxi to arrive through dispatch updates and the map provided. The app even lets you pay by credit card if you are low on cash after a long night out. Best of all, it is completely free.
TalkLocal can also connect you to taxi services. Use TalkLocal to put you in touch with the best taxi companies in your area. Our mobile app for iPhone and Android is currently in beta testing, and will officially launch soon.
