Standard Calculator StdCalc is a simple yet powerful calculator designed to be more functional than the default calculator installed on your Android device. It is developed by Roaming Squirrel and falls under the category of Utilities & Tools. The calculator features a variety of modes and includes a tip calculator and a loan calculator, both of which can be accessed from the menu.

The main calculator features include decimal mode, fractions mode, running total of each calculation shown as it is entered, and full text of the calculation displayed as it is entered. Additionally, the output text can be set to scroll either horizontally (the default) or vertically. The full text of each calculation is stored in the history, and the results of each calculation can be reclaimed from the history and reused in future calculations. There is also a range of color schemes to suit different moods.
