On the cli my favorite calculator of all time is Qalc. It's fucking amazing.
You can be like "1 km to mi" and it will give it to you.
For some reason the screenshots show the gui but imo the cli is where it's at
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.
much thanks to @gary_host_laptop for the logo design :)

2 plus 2 is 4 minus 1. That's 3. Quick maths.
How many lights do you see?
Also nice GeoGebra, OpenSource from Austria (EU), online, Android, iPhone
Not FOSS but great, OmniCalculator from Poland (EU), online, free, a collection of 3718 calculators for every task.
I use this one. It isn't FOSS, but it's a one-time purchase to remove ads. It has a lot of added features, like algebra and unit conversions, and requires no permissions.
The last time I wanted to do something for privacy, someone laughed at me saying "They don't want to make a google mail because google spies on us". Eh I wish you could read all this shit but you're old and you don't care about privacy ig
Why does a calculator need my fucking email address? We're not pen pals, just do this arithmetic.
Data can’t be deleted
The developer doesn’t provide a way for you to request that your data be deleted
Not big fans of the GDRP I assume 😂
I mean, there are a gazilion of calculator apps around?
I have a good experience with CalcYou.
I've personally found the behavior of 'clear', spacing of buttons, and lack of customization capable of fixing those to be rather annoying. They're the same complaints I have with Fossify's calculator app. I'm currently using OpenCalc since they don't have those issues.
I don't understand. If I am using Android already, how does calculator make privacy worse? Calculations are not exactly revealing.
And if I am using graphene, why would I consider using any Google app?
Graphene is basically android too. If you install lineage without gapps for example, I think you'll have great privacy. About the second, I don't know..

Lineage or Graphene, yes?
I just bought a second Pixel 4a and can therefore now afford the slight bricking risk to install Graphene or Lineage.
Lineage and grpahene do different things. Research and find the right for yourself. And instead of lineage you could find a crdroid on if you for example want more customization
Thanks I've uninstalled Google's calculator and installed OpenCalc
Welcome to 2025 where we discuss FOSS Calculators that don't collect your data... how did we get here again?
Nowadays even calculators have terms of service and a privacy policy that is longer than many novels. Some probably have forced arbitration also.
rofi-calc
is awesome. It's so convenient to just press a keyboard shortcut you have defined and instantly being able to type or paste your equation, no having to wait for a complicated GUI to load, no clicking required. You can just pop it in whenever you need. Also it does unit conversions, instead of a math equation you can just type 10 inches to cm
or 10 eur to usd
or 100 celsius to fahrenheit
or 100 to binary
which is a huge time saver.

Besides, it's rofi and rofi rules 😎
I didn't know about this! I already use rofi for a few different things, so I'm going to get rofi-calc working too, it'll fit perfectly into my workflow. Thanks!
Rofi is cool but don't forget about qalculate (the backend)
wow, great program! I've been using bc for some simple calculations before, but this just replaced it!
Congratulations, Google, you can spy on math now.

I've been looking for a calculator app for years now that fits what I need I need it for and have yet to find a good one. There was a good one a few years ago called function-something which allowed you to create your own mathematic expressions and it was super awesome, but it's been discontinued... :(
EDIT: To those asking, I've essentially tried the first 50 that show up under "calculator" in Google Play. If you posted it, I've very likely tried it and found it lacking.
yetCalc?
I don't know if it's on the play store.
I'll give it a go.
RealCalc is nice - it emulates a scientific calculator, and doesn't ask for any permissions.
That's the one I use. I even paid for mine since I like it so much.
did you try calculator++? on fdroid. it has a lots of operations, a function plotter and a floating window mode
There's also Arity. It isn't the best interface, but it has functions, variables, and graphs.
I was also using Unitto for unit conversions, but apparently the creator doesn't want forks or for f-droid to host it, so I'm looking for another one.
If you have ever used an HP RPN calculator (which are clearly the best calculators), there is Droid48, which emulates the HP 48GX.
Desmos scientific calculator isn't open source but it is what I end up using most of the time. It just does float stuff though, it can't handle something like (10^100+1)-10^100
It also doesn't support nearly as many features as the graphing calculator does, for some reason. But it formats everything very nicely and you can copy and paste as latex
What's wrong with GrapheneOS calc app?
It's "com.android.calculator2" which suggests it's the AOSP calculator or a close fork of it.
I have no issues with it. It calculates. That's all I need it to do.
It's terrible to use, and it has no themes, so using it at night is a death sentence for your eyes.
Fair point
What is u calculating in the middle of the night tho 🤣
How many hours of sleep I'll be losing /s
