We have developed a highly realistic Curta simulator that allows users to fully reproduce and follow the calculations performed by this unique mechanical computing machine. The simulator supports all four basic arithmetic operations—addition, subtraction, multiplication, and division—while replicating the original operating experience as authentically as possible.

All controls of the Curta have been faithfully recreated in detail: the decimal selector, clearing lever, crank, and setting sliders function exactly like those of the original machine. This makes it possible to calculate with the simulator just as you would with a real Curta—ideal for technology enthusiasts, collectors, and anyone interested in gaining a deeper understanding of this historic calculating device.

We offer the Curta simulator as a Windows download for CHF 10.–. After successful payment, the customer will receive a Windows download link via Dropbox or WeTransfer.

Immerse yourself in the fascinating world of mechanical computation—conveniently and anytime on your own computer.
