Wombat review
A programmable Linux calculator for precise, unit-aware work with a persistent session.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Wombat is a GNU/Linux scientific calculator built around the Numbat programming language. It is aimed at Linux users who want high-precision calculations alongside physical units, dimensional analysis, and a workspace that retains definitions between calculations. The persistent interpreter supports variables, functions, and imports, making it suitable for recurring or programmable calculations rather than only one-off arithmetic. Its desktop-focused Linux scope makes it a less natural fit for people seeking a calculator app across operating systems.
Unit handling is a defining strength: Wombat supports dimensional analysis and natural-unit conversions, and includes browsers for units, constants, and functions. Entries can be clicked to insert them into a calculation, while autocomplete suggests variables, functions, units, and constants. A scrollable, syntax-highlighted history keeps earlier calculations visible. Custom startup definitions let users load their own variables, units, and functions. Together, these capabilities favor users who work repeatedly with scientific quantities and want unit-aware context close to their calculations.
The interface is built with GTK4 and libadwaita for Linux desktops and mobile devices running GNU/Linux, with touch-friendly controls. Installation options include the Arch User Repository, Flathub, and building from source. Wombat is open source and has a free plan. Its focus is narrower than a general-purpose calculator: the described capabilities do not extend to equation solving or a broader set of calculator features. Choose it for a Linux workflow centered on units, precision, and persistent programmable calculations; consider another calculator if you need cross-platform availability or broader solving tools.
Wombat pros and cons
- Where it wins
- Dimensional analysis supports physical units and natural-unit conversions.
- A persistent interpreter retains variables, functions, and imports.
- Browsable calculation history, autocomplete, and click-to-insert references.
- Where it doesn't
- Designed for GNU/Linux rather than cross-platform calculator use.
- Calculations are centered on Numbat's programming-language interface.
- Does not cover equation solving or a broader range of calculator features.
