We have collected here some useful links to help you find out if Calca is good.
Check the traffic stats of Calca on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Calca on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Calca's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Calca on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

This is remarkably similar to Calca.app, which I still use occasionally. http://calca.io/ I love that yours is web based! Can see it being much more reusable in a number of use-cases. Calca was originally MacOS/iOS, but has since been ported to Windows. I think that the notation in Calca to use a `=>` to display results maybe adds a bit more clarity to the math expressions, but your display style seems to work... - Source: Hacker News / about 2 years ago
This looks fantastic. I will definitely give it a spin. I've been tracking what I call "computational scratchpad" apps for a while now but haven't found one that fits my environment/workflow yet. Maybe Heynote will. Here are some others that I've looked at: * https://soulver.app Granddad of them all, Mac-only, proprietary, expensive * https://numi.app Mac-only, proprietary, semi-expensive. Has a Github and claims... - Source: Hacker News / over 2 years ago
This is all in calca syntax so you can download that for free and copy-paste this whole post into it and change the numbers for your car or electric rates. Calca is like a spreadsheet met a text editor, it's great. I don't work for Calca it's just a great tool. Source: over 2 years ago
Soulver. Useful to do calculations. I often find it useful while coding. Calca is even more powerful (you can almost program in it), but a lot less polished. Source: about 3 years ago
The flip side to this is that Julia is a very capable general purpose engineering calculator and simulator. For example, calculating friction in hvac ductwork, voltage drop in long electrical circuits, solar gains for windows or solar panels facing various directions, cost/benefit analyses of thicker or thinner roof insulation and so on... These are all 1 to 10 lines of code so there isn't a big porting cost in... - Source: Hacker News / over 3 years ago
There are a bunch of these shared here over time. https://bbodi.github.io/notecalc3/notecalc https://dedo.io/ https://numbr.dev/ https://github.com/iaredreich/calcutext https://calca.io/. - Source: Hacker News / over 3 years ago
Neat! I remember a Mac app with a similar concept from ages ago: http://calca.io/ Glad to see something like it for the web! - Source: Hacker News / over 3 years ago
Thanks, yeah there are more similar plugins (I didn't know sniprun), the idea came from calca, which is great, but it lacks linux support. What I was missing from similar plugins was persistence, I mainly use it for small calculations for electronics, which I then include in the repository and I wanted for the results to stay there.

Have you tried Calca? https://calca.io/ It works really great on mobile too (even their website is not updated it works fine on latest OSs). - Source: Hacker News / almost 4 years ago
This seems to be a shadow of Calca. https://calca.io. - Source: Hacker News / almost 4 years ago
I've found that the Calca[โ ] format hits a nice sweet spot between using an ordinary calculator and running a spreadsheet. [โ ]: http://calca.io It's particularly suited to calculations I'm doing by fetching various numbers from websites, and for the most part it 'composes' by just copypasting a calca into another one. Basically where the numbers mean something, aren't stable / I don't know them all when I start,... - Source: Hacker News / almost 4 years ago
Looks nice! Making the result blocks non-text is handy. Any plans to open source this or sell a desktop version? I've long been a fan of http://calca.io but it doesn't run on Linux. There's some other versions out there but they tend to be flaky. - Source: Hacker News / almost 4 years ago
For calculator languages, I think there are several choices. Depends a bit on what you know, and what you need... Frink (https://frinklang.org/) has been around for ages, and is rooted in physical unit conversions Calca (http://calca.io/) has come up a handful of times. It looks pretty reasonable R, if that's your flavor Anything with a REPL. Though the OP suggests these are cumbersome, I'd counter argue that... - Source: Hacker News / about 4 years ago
If youโre a bit technical Iโd strongly advice giving Calca a go. I use it for alll kinda of stuff from basic math to testing out programming logic. Source: about 4 years ago
It might be overkill, but Calca is excellent and handles units well (among other things). Source: over 4 years ago
Http://calca.io is a decent alternative thatโs available on Windows and still maintained on mobile. - Source: Hacker News / almost 5 years ago
Iโve used Numi, Soulver, and Calca. For day-to-day use Numi feels the most enjoyable to me; however, when I need something more heavy duty, Calca canโt be beat http://calca.io/. Source: about 5 years ago
Another good one is http://calca.io, very like Soulver but also has simple graphing, runs on mac, iOS and Windows. - Source: Hacker News / over 5 years ago
My favorite is still Calca (http://calca.io) - it hasn't been updated for a while, the developer has been working on other things, but it still works for me. - Source: Hacker News / over 5 years ago
