An adding machine on steroids

Running tapes is just the beginning with all of the features you expect from even the most expensive mechanical devices, but, with awesome features that are possible only with this digital tape number processor.

Using this tool, you can do amazing tasks that you will never be able to do on that plastic or metal monster that is taking up desk space sitting next to your computer.

Normal view


All functions are visible. The panel shown here on the left can be shifted to the right side.

There is no limit to the number of memories. Separate arithmetic can be performed on the selected memory value.

Three types of line numbering, including none, are available on the tape.

The Subtotal and Note columns are optional.

Minimum view


The smallest view takes up the least desktop space to allow using all of the tape functionality with minimum interference with other applications.

A virtual numpad


Built for touch screens

On tablets and monitors with touch screens, the virtual numpad makes running tapes a breeze. Available in any view, the virtual numpad works the same on touch screens as the numpad does on a keyboard.
