JCalc is an extended calculator application. When you open the app, you will get a splashscreen of a Dalmatian (yes, the dog…it’s totally random). From here you will see a Calculator. When you enter a function into the calculator, it will display it on the screen above the calculator. However, once the function scroll off the screen you can not see them anymore. It would be great if you could scroll the display screen. You can see the rest of the calculator options by scrolling your finger up/down on the calculator. This is a simple but functional application. JCalc is available through the BigBoss source.
