App Highlight: Caligator is a Beautiful Calculator & Converter

You will find lots of useful applications for Linux, however, not all of them focus primarily on the user experience.

Sure, the user interface may end up being something nice and simple but not necessarily pleasing to look at.

For the very same reason, I wanted to have a calculator and converter app on Linux similar to Numi (which is available only for macOS). I know we already have a superb calculator app like Qalculate but I am not a fan of its simple looking (read boring) interface.

Recently, I came across something very similar – ‘Caligator‘ made by Team XenoX.

It’s Not Your Typical Calculator

When compared to traditional calculator apps – this is something different. It lets you calculate or convert by simply typing on it (as you can see in the image above).

Just like you type in to search for something on Google (or on privacy-oriented Google alternatives), the user has to just type the instruction naturally to get the output.

Not just limited to the ability to understand instructions for conversions, it also displays the output as you type. So, you do not have to wait and press another button to get the result.

Feature Overview

For now, you can perform any kind of arithmetic calculations and convert things like Currency, Length, Weight, and more.

You can choose between a dark or light theme. However, for now, the app might get stuck when you try to change the theme. Atleast, I’m facing this issue right now on Pop!_OS 19.04.

They would fix the issue in the next update probably.

In addition to what’s possible, the developers have planned (as per the official announcement) the following features for the next update:

  • Font size preferences
  • Export options
  • Click to copy
  • More themes

Getting Caligator on Linux

You can directly head on to find its GitHub releases page and download the asset suitable for you.

For Linux, they have three file formats available: AppImage, Deb files and source code.

I suggest downloading the AppImage file. You just have to give it execute permission and then you can run Caligator on any Linux distribution.

In addition to Linux, you can also try it on your Mac/Windows machine.

Wrapping Up

Caligator is still under development so you may encounter bugs. If you do, please open a bug report for the developers on their GitHub repository.

While this may be in its early stage of development now, it is definitely an impressive project which should incorporate interesting features in the near future.

I remember that elementary OS also has a similar application called NaSC. You may want to check it out as well.

  • Good idea maybe once is is comprehensively complete. It still is too early I think. For Ubuntu 18.04, the drop-down the change the theme didn’t even so much as drop down and it froze the app.

    I typed in:

    4.25in to mm

    And it did nothing, but it could do

    4in to mm

    Will check it out again in a few months and see where they get with it.

  • Sounds pretty nifty! I have been using “ConvertAll” for unit conversion, and It’s very intuitive and powerful, and can convert from/to just about anything!

    I use a few different calculators, and although I am not a fan of most Gnome apps, I do like the “Gnome calculator”, due to the fact that it keeps a running history, so that if you need a result or value from a previous calculation, you can just scroll to it and click on it to enter it where you need to, or copy paste it.
