NumWorks
NumWorks is a French calculator manufacturer that has produced two models of calculator. Both calculators are source-available graphing calculators and have their hardware and software designs available under a Creative Commons license.[4] Its first calculator, the N0100, was released on August 29, 2017 in France and the United States and is geared towards high school classrooms and students.[5] The calculators use Python as their programming language, rather than a proprietary language (e.g. TI-BASIC used by Texas Instruments calculators).

Development
Romain Goyet, the CEO of NumWorks, started the company in 2015. Before starting NumWorks, he was a software engineer at Apple who also contributed to open-source projects such as Linux.[6]
Features
The calculator was specifically designed to be modded using 3D printing, 3D models, firmware operating system source code, schematics, and board layout details available to the public under a Creative Commons License.[6] The software on the calculator is updated on a monthly cycle.[1] Updates can be downloaded to the calculator from its website using WebUSB or by building the operating system from its direct source.
The NumWorks calculator also includes an "exam mode" which removes all Python programs, resets all apps, and disables certain features. It can be disabled by plugging the calculator into a power source and selecting disable on the popup that appears.
On March 22, 2019, NumWorks released an app for iOS and Android.[7] It features the same functionality as the physical calculator except it does not have data persistence.
