FlickCalc Calculator for Android is a scientific calculator app that uses the same unique input method as used in the FlickKey keyboard. The calc keypad uses just six keys. To enter numbers or commands, just "flick" (press and slide) in the direction of the number or command you desire. For the center command, just tap the key.
Once you become accustomed to the flick-key input method, the method is both quicker and more accurate than pressing on of a large matrix of buttons. FlickCalc is amazing on small devices.
