Calq: A Quick Calculator At Your Fingertips


I don’t know about how everybody else work, but I am the kind of person who always need to do quick calculations. From a simple “how much is the change” or “how much should I pay for everything” to something like “how much IDR (Indonesian Rupiah – my country currency) should I pay for this USD (US dollar)”. I have my calculator app in my cellphone for everything I need to count while I am on the road; but in front of my computer – Mac or Windows, I use Calq.

There are already too many calculator applications out there with extra bells and whistles. Why choose this one?

Well, because it’s quick, cute and simple.

Quick calculation with Calq

The idea behind Calq is to have a calculator handy when you need to do some basic calculations quickly. You bring it out, do the calculation and go back to whatever you are doing. Calq will quietly disappear out of your way.

To use it effectively, you need to add Calq as a startup item in your account preferences. Don’t worry of bloating your startup process because this one is so small that you barely feel its existence.


After tweaking with several preferences at the first time startup (including the chosen hotkey combination and the position of the display), Calq will sit quietly in the background and not show itself anymore until you summon it.


Whenever you have the urge to calculate, just press the hotkey. The one on my Mac is set to Option + Command + C, but you can set it to anything you want. A small transparent window will appear and you can use the computer keyboard to put the numbers there. This small window will stay up as long as there’s keyboard activity. If you don’t type anything for a few seconds Calq will hide itself until you activate it again. Calq will also hide itself immediately if you activate another application.

There you have it. My personal choice of practical calculator app. If you have other favorite alternatives, I’m all ears. Use the comment below.
