Hypatia review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Hypatia is a free, open-source, text-based RPN scientific calculator for 64-bit Windows. It is aimed at people who prefer reverse Polish notation and want to automate calculations rather than work only through individual expressions. Scientific functions and built-in unit conversions cover core calculator tasks; named variables, custom constants, and user-defined functions make repeated work easier to express. The desktop interface can also run from the Windows command line, giving it a scriptable character that suits technical solo users comfortable with text-based workflows.

Its programming features are the clearest distinction. Scripts can include loops and conditional statements, and the calculator supports iterative calculations and Monte Carlo experiments. Users can review, edit, and reuse previous inputs, read data from files, and export results. That combination can help with repeatable calculations and small computational experiments. Hypatia also documents means, medians, and standard deviations, but it is not intended for statistical analysis, so dedicated statistics software is a better fit for that work.

Hypatia is free and open source, and the published description identifies no paid tiers. Its scope is deliberately limited: it is a Windows desktop application, and it does not support matrices, vectors, or complex numbers. Those omissions matter for users whose scientific work depends on linear algebra or complex-valued calculations. Pick Hypatia if Windows and RPN suit your workflow and you want a programmable calculator with file input and output; choose a different tool if you need broader platform support, matrix or complex-number operations, or a statistics-focused environment.

Hypatia pros and cons

• Where it wins

  • Reads input files and exports results; prior inputs can be reused
• Where it doesn't
  • Windows-only, with no support for other listed platforms
  • Does not support matrices, vectors, or complex numbers
  • Not intended for statistical analysis
