The calculator app reimagined for engineers, scientists, and students. Not only does it handle complex numbers and incorporate numerical error bounds, but it also boasts an intuitive and sleek interface that seamlessly presents scientific formulas. This tool goes beyond the standard, featuring a design crafted for swift, intuitive, and concise usage. Stripped to its core functionality, it ensures a clutter-free experience without any superfluous components.

Intrigued? There's more to come. Future updates will allow you to create custom functions, assign variables, use preset constants, and obtain multiple results for non-unique functions (e.g.: sqrt(-1) = {-i, i}). Moreover, we're working to enhance performance, broaden multiplatform compatibility, and more. Engineer's Calculator: your essential tool for engineering calculations.
