Swift Calcs is described as 'The Collaborative Computational Notebook Built for Modern Engineering. Enter math as it appears on paper, get instantaneous results, and share your calculations with colleagues and clients. No special syntax, no software, no headaches, no kidding' and is an website in the education & reference category. There are more than 25 alternatives to Swift Calcs, not only websites but also apps for a variety of platforms, including Windows, Linux, Mac and Android apps. The best Swift Calcs alternative is MATLAB. It's not free, so if you're looking for a free alternative, you could try Overleaf or fxSolver. Other great sites and apps similar to Swift Calcs are Mathematica, Calcpad, Maple and SMath Studio.
