Description
King Calculator is a free, powerful calculator designed to make calculations easy.
Its flexible expression editor lets you enter, edit, and solve calculations naturally. Move the cursor anywhere in an expression to make changes without starting over, whether you're working with basic arithmetic, fractions, percentages, or more advanced formulas. Color highlighting keeps expressions easy to read, even as they become more complex.
Switch between the simple and scientific calculator views by rotating your device. You can also enlarge the display with a single tap for easier viewing.
King Calculator works on phones and tablets of all screen sizes. Your calculation history is always available, so you can review previous results, reuse expressions, or save values to memory. Choose between two memory modes: classic Save/Clear memory, or business-calculator memory with M+, M-, and MRC buttons — the familiar style of a cash register.
The calculator also supports graphing, very large numbers, and a wide range of mathematical functions. It's completely free, with no paid features to unlock and no unnecessary permissions.
Whether you're a student, engineer, teacher, or simply need a reliable calculator every day, King Calculator has the tools you need.

[Fixed] Great calculator, however I don't know how but from a few days ago it started to have some visual bugs, mainly the settings page having white text on its white background which makes them invisible. And another is the answer preview number which has the same white text issue on bright background. Tried on my friends phone and same visual bug. Update²: the 2.3.5 seem to have fixed it, thank you for the great support.

Why you removed classic theme????? And now all my history of calculations is empty:(

Very easy to use, and it includes many functions. Issues I had earlier, Plot not working properly if function starts with a negative value and inability to read the Settings page and error messages, have been fixed. I am also an iPad user, and I wish you had a King Calculator for iPad, too.

I keep hitting either they equal button or the "ansr" buttons instead of a letter or period & the history doesn't show long line of added numbers aka my shopping list prices & total. I'm going to find nothing calculator asap.

Horrible design update. After so many years of use. I rolled back to 2.3.5 apk version. I won't update again if you don't give us the option to the old style. I don't like your colorful LGBTQ version. We need functionality. Give us the option of the old design with bigger buttons and simpler use.
