TaxiCaller is a free travel and navigation app developed by TaxiCaller.com for Android devices. With this app, you can book a ride with licensed taxi companies in more than 40 countries. You can book a ride now or later, and hail cabs through the app by pressing on a car closest to you. The app allows you to type in your pickup address or drag and drop your location on the map. You can also save your favorite places for easier booking next time.

The app provides fare and time estimates before you book, and you can choose specific options for your trip, such as vehicle type and payment type. A booking confirmation pop-up appears once you've booked a ride. You can track your taxi on the map to see it moving to your location in real-time. The app also offers a trip and receipt history for past rides, and you can rate the driver and comment on your experience. Additionally, you can log in with Facebook and share your ride option.

Please note that if you don't see any vehicles available, TaxiCaller may not be in your area yet. You can email them at to let them know your city or if you have any problems booking. For more information, visit their website or follow them on Twitter or Facebook.
