MicroCalc is a spreadsheet implemented in J2ME

MicroCalc is a spreadsheet implemented in J2ME (Java 2 Mobile Edition), this version of Java language is used on devices with small hardware footprint, such as mobile phones and PDAs.
MicroCalc interface is similar to the desktop spreadsheet software such as MS Excel, with certain limitations regarding small screen size of handheld devices and general limitations in available resources, such as heap memory size (this limits the amount of data that can be placed on a sheet), and application code size.
