GrapeCal is an application seemingly used to calibrate the touch screen of a device. It requires device specific firmware as well as other requirements in order to be able to run. The GUI itself is quite plain, with a list stating which files are present and which files are not, as well as a settings and quit button. Inside settings, you can adjust the "verbose level" from levels 1 to 3, as well as enable or disable serial output and production mode.
