Earlier quoted context omitted.

If you're using OS X, try using Spotlight or Alfred directly (Keypirinha[0] is a reasonable Windows alternative) - just type in `1 + 2` and you get the answer without launching a special app. There are plugins for conversions as well. [0]. https://keypirinha.com/

Spotlight correctly interprets numerical expressions, but it also treats them as search queries for the entire filesystem, resulting in an expensive retrieval process after every keystroke. It's the most convenient, so I use it anyways, but the end result is that cpu starts to overheat for a query as simple as 1 + 2.

I turn everything except calculator (and settings menu) off, so this problem goes away.

I never really want to use spotlight to browse to some random directory or file on my filesystem, for me it's strictly for calculator and opening the Bluetooth settings...

What is it with people calling their applications "beautiful"? What's so beautiful about this?

Clean and unobtrusive design, with a focus in typography, layout, ample whitespace, and a color palette that provides context and visual information without being gaudy and flashy.

With that said, it looks exactly like it could be a random CLI application running in an Oh My Zsh theme. Not much differentiation there.

EDIT: I feel like this app could be created in a few hours by wrapping a context-aware unit/currency conversion library with Rich Python [0].

I would totally use this if it were an extension to Emacs. I keep lots of calculation results in text files, and edit them in emacs, but I don't want to use a totally separate app whenever I want to enter and calculate some math within a text file.

A lot of people mentioning Soulver as a great alternative. But after running into limitations with Soulver, I eventually discovered Magic Calculator, and I fell in love. It allows for more precise calculations, and it's way cheaper at $4: https://apps.apple.com/us/app/magic-calculator/id421993158?m...

Soulver is a similar app for macOS, iOS, and iPadOS with shared documents in iCloud Drive. Check it out if you’re looking for something like this to go!

Would love to see a web version

You want your calculator to be a web page?

Check out calc (M-x calc RET). Full RPN calculator built into emacs, with matrix and symbolic solving capabilities. Best calculator I have ever used.

What is wrong with “bc” ;-) half joking, anybody else who uses bc? I am by no means an expert, just using the regular add/multiply and sometimes a variable. This looks way better though.

It's my go-to calc too but I always start 'bc -l' in case I need decimals.

I also just type bc -l in one of my iterm windows. Usually that gets me my answer quicker than launching an app or worse, using a browser.

I find that calculators remain weirdly unergonomic on most Operating Systems. There are so many times where I want to do some quick math but feel hobbled by the insistence of calculator software writers to ape physical calculator design -- Numi seems like a cool step in the right direction

I used to have an amazing calculator in Windows XP/7 called powertoy calc. It was so simple to use and had amazing powerful features too. Huge help while I was in engineering college.
