Show HN: All desktop calculators are wrong, so I had to build my own

Qalculate!

My favourite desktop calculator so far is Qalculate![0] for similar reasons, and I basically never have the keypad shown. It uses libqalculate, which also provides a console version of the same library. It's incredible and I love it. [0] https://qalculate.github.io/.

40 Hadiths

There's been a lot of suggestions for alternative desktop calculator programs that try to remedy some of the issues outlined. I've had similar experiences/annoyances with calculator apps, most of which to copy handheld calculators but without the satisfaction of buttons yet the power of a programming repl/solver. I've currently settled on MathLab's Graphing Calculator[0] which has very similar design elements for any larger scale calculations. My second choice if the calculation requires estimates or units is obviously Wolfram Alpha, but the need for connectivity, lack of calculation history and speed leaves it lacking as a quick calculation tool.

Soulver 3 for Mac

I'm surprised no one has mentioned Soulver yet (https://soulver.app/). I have used it for years -- it looks like it has pretty similar functionality to this but (IMO) with a more native-feeling UI. I love it. I don't think it supports as wide a range of math, but it does seem to pass the accuracy test given in the article (sin(exp(37))). It also lets you assign variables which I find handy. On the other hand, the propagation of uncertainty in Chalk is very cool.

Insect

I recommend https://insect.sh (you can install it through NPM to use it locally). Does simple maths well, does functions, does units, does conversions... Pretty cool shell calculator.

Frink

I really like speedcrunch also, another really cool calculator that is more of a language is Frink https://frinklang.org/.

Numi App

I haven't seen Soulver, but it looks very similiar to the one I use on Mac, called Numi. On Android, I use an app called CalcNote which works in a similiar way. Neither does graphing, but you can do common formulas and functions like cos/sin/rad. I use numi for simple calculations, and find it fantastic when I'm trying to figure out project stuff. A recent use is entering wall dimensions to figure out square footage and compare different building materials. I often leave most of my old calculations in numi like a long-lived numerical memory. https://numi.app/ https://play.google.com/store/apps/details?id=com.burton999.notecal.pro.

Free42

Have you seen Free42, "...a re-implementation of the HP-42S Scientific Programmable Calculator and HP-82240 Printer?" [0] It is available for Android, iOS, Windows, macOS, and Linux. (At one point there was even a version available on Windows Phone 8.) Perhaps it checks your boxes of good RPN calculator, available on all platforms. I don't know how much an HP-42S feels like a 41C. In any event, thank you for ralc. I've off and on been searching for a nice web-based RPN calculator. [0] https://thomasokken.com/free42/.
