In 2024, the iPad finally received its own native calculator app, marking 40 years since Apple introduced its first graphical user interface (GUI) calculator for the Macintosh in 1984. Designed by Chris Espinosa at just 22, the original calculator was a favorite of Steve Jobs, who was known for being critical of design choices. After several iterations, the calculator was approved, but only after Jobs offered harsh feedback on its color and button sizes. The design evolved through the years, with significant changes occurring in 2001 when Apple transitioned to Mac OS X, adopting a minimalist aesthetic that emphasized user-friendliness and simplicity. The LEGO set inspired by Apple’s calculator designs illustrates this evolution through four distinct stages. It starts with the black-and-white calculator from 1984 and culminates in the modern scientific calculator. The set consists of 821 pieces and is designed to appeal to fans, students, and tech historians. The designer, known as The Art Of Knowledge, incorporated interlocking plates for a tactile finish, aiming for a scale that closely matches the actual app designs. While this model is currently a fan-made concept, it can be voted into production through the LEGO Ideas platform. Apple’s design journey also reflects broader influences, particularly the impact of Dieter Rams and Braun’s design philosophy. The 2007 iPhone calculator featured a black and orange color scheme but went through various changes before adopting circular buttons in 2024. This evolution not only highlights Apple’s commitment to design but also showcases its ability to blend functionality with aesthetics over the decades.
