The system keyboard may be better fit for the calculation .
The built-in keyboard is not a standard QWERTY keyboard.
I use Unexpected Keyboard.

Revert colour palette changes to original, as shown in the pictures. Current colour palette has the colours way too muted and close together.

First, I'd like to thank you for preserving this piece of software. I haven't seen a sane calculator app since cyanogenmod days.

The letters keyboard keeps disappearing in a frustrating way.
Example scenario: I open the app, press that arrow icon to show letters, type "x" (letters disappear), press the arrow icon again, type "+y" (letters disappear again), press the arrow icon again, and so on.
It seems that it disappears when the view changes.
I'd like it to always remember its last state. So if the letters were shown before I close the application and then reopen, it should keep them shown.

arity only makes a strip grey and then has black above it. i think it should cover everythinf and remove tbe black top. also, i think grey should be the dominant color and black should be the top strip (secondary) but this could be an option. if it were to be an option allowing users to input hexs for preferred color would be ideal. thanks

do you know how in blendwr you can click on an axis and it will bring the camera exscrly there? implementing somrthing similar to blendrrs syatem would be great. also, not locking on to the centre but allowinf movement (like how godot android does) would be awesome too

It would be nice if there were some haptic feedback on button press, otherwise it feels dull. Not sure how this is accomplished, but florisboard has it so it might be a good place to look.

Hi, thanks for reviving this gem of calculator. I have one difficulty, which I also had with the ancient original: it is pretty hard to enter something like -1*3 because Arity interprets this as ans-1*3 leading to unwanted results. My only workaround is 0-1)*3 or something like that.

Could this behavior be changed? Do you have some other workaround?

As someone who sometimes does math in conjunction with computing, not needing to convert from decimal to binary or hex would be convenient. Being able to represent numbers using octal would also be nice, though converting between that and decimal or hex is trivial.
Out of my interest in mathematical notation being able to specify how values are represented/possibly custom symbols and bases would be cool but not particularly useful outside being interesting, so that is probably not worth much effort.

I wouldn't mind doing this myself but I'm not particularly familiar java nor development for android
though I wouldn't mind trying if I had a short overview of what is relevant.

Show candidate list from predictions below the input box, that can improve a lot of input efficiency.

for example "f", show the following:

• "f("
• "f'("
• "floor("
  more...

for example "si", show the following:

• "sin("
• "sin'("
• "sind("
• "sinh("
• "sinh'("
• "sign("
  more...

Maybe related to permissions or some kind of FS inotify or inter-apps communications bus.
Maybe this is not an issue with Arity 1.29 as I didn't use the feature before : once captured a 2D function picture, the capture won't show in the gallery (Pictures/Screenshot) (latest Aves from D-Droid or native G-photo). Although, it shows in file explorer (Simple File Manager).
Once rebooted, the screenshot shows everywhere expected.
This is not a huge issue, as we can immediately find the capture in file explorer.

that's it, thanks for the good work.

The some buttons are invisible, following screenshot.
This issue started in version 1.44.
In the old version 1.42, have no this issue.

System: Android 13
App version: 1.44, 1.46

Right now, the keyboard is functional but extremely cramped. Adapting something similar to the official Google Calculator app might help with usability.

Current:

"Mockups" (aka, overlaying the Google Calculator keyboard)

Hello everyone,
Currently the app supports only radians. It would be nice to have a button or a section in the Settings for changing between radians and degrees. You could add that option in the Settings or add a button writing 'RAD' or 'DEG', like the other calculator apps for easy accessibility.

Hi,
I don't know why this one is wrong. The Arity's result is tanh^-1(2%^9) = 5.5511151E-16
But the correct result is tanh^-1(2%^9) = 5.12E-16.

Letter keyboard not available in landscape mode.

And also can i make the kayboard always is open. Without having to click on the button to exapnd it every time i open the app.

Hello,
I find your calculator very useful and use it almost every day at my university. I would like to suggest a feature that would improve readability of calculation results.
I think the result of an equation would be much more readable if it used thousands separators.

For example, instead of displaying a large number like this:
4789237894
The calculator could display it like this:
4 789 237 894
Or like this:
4'789'237'894

...making the result much more readable! Let me know what do you think about it. 😃

many of us use webscrapers like obtainium and without a .apk posted getting updates doesnt work

The delete, enter, and unfold arrow icons look a bit out of place.
Using SVG icons would be much nicer. Suggested icons:

• backspace
• enter
• unfold

Please make font on buttons larger.

Version 1.52 introduces haptic feedback and dynamic colors, however the device setting to disable haptic feedback is ignored by the app, and there seems to be no in-app user setting to disable haptic feedback, like there is for dynamic colors.

Ideally, please honor the device setting to enable or disable haptic feedback, or at least, please provide an in-app setting for people who find haptic feedback annoying.

Thanks for your time and attention.

The use of a PEMDAS order of operations is incomplete, resulting in incorrect answers to algebraic expressions that include multiplication by juxtaposition. E.g. 4÷2(3) should result in a value of 2/3, but instead is resolved to 6. Granted there is no official consensus on the order of operations in theoretical mathematics, however the vast majority of engineers and scientists are more familiar with a PEJMDAS order of operations. Whether this is simply to be corrected or given a configurable setting I leave at your discretion. On a final note, I would like to congratulate you on a truly remarkable application. You do the open source community proud.

Please add the light theme

When I press the backspace key, it only deletes one character. It would be nice to be able to erase the whole calculation or automatically erase several characters in quick succession, like on a PC (with a speed option).
