Based on actual old calculators that were in use before the invention of micro chips and vacuum tubes, these old calculators were commonly found on desks in the early 1900′s. In these machines, addition and subtraction were performed in a single operation, as on a conventional adding machine, but multiplication and division were accomplished by repeated mechanical additions and subtractions.

Now you can get your hands on one of these old calculators. We guarantee that you’ve never used a calculator as unique as the Old Calculator app.

FEATURES: moving switches, mechanical sounds, and animated buttons.
