Engineers have depended on Excel, which is prone to mistakes, for vital calculations.

Alternatives like Mathcad are cumbersome and less productive.

Blockpad, with spreadsheets and math documents together, avoids mistakes and saves time.

Blockpad is familiar

It works like word processors, spreadsheets, and drawing software you already know.

Clear and productive
