Calc4m.m1 is a powerful non graphing scientific calculator with an unwieldy name.

What I like about this calculator is that every entry or operation takes only a single keypress. That makes it fast and easy to use for basic arithmetic  as well as complex math.

The available keys are shown right on the screen so you don’t have to remember them. Each of the standard cell phone keys has two functions which are shown graphically on the screen.  The function in the top left corner is activated by a short keypress, the function in the bottom right corner is a activated by a long keypress.

So to calculate 4 + 5 you press the 4 key, then do a long press on the 1 (+)  key, press the 5 key and then press the # (=)  key.

The up and down arrow keys switch between six screens of offering different types of operations including, trig functions, number base conversions, four memory registers and various unit conversion like liters to quarts, fahrenheit to Celsius, lbs to kg and  mph to fps

Other keys:  Left = undo; Right = redo; long press call = jump to basic artithnmatic screen.
