Description
AlexCalc is a scientific calculator with some neat features: * nicely formatted (LaTeX) equation display. This avoids the need to count brackets to make sure the equation was entered correctly. Also includes LaTeX code generation. * complex number support, in rectangular or polar form (e.g. `3 + 4i` or `1 angle 90`) * variable storage (e.g. `123 -> x` then `3*x^2 - 4*x + 5 -> y`) * units in equations, and conversion (e.g. `1 inch * 3 ft to cm^2` or `sqrt(60 acre) - 100 ft`) * can enter input by button presses, typing, or copy/pasting. Button presses are all converted to plaintext input for easy copy/pasting. * equation display is simplified upon pressing enter. This means that when entering an equation, it is usually possible to look only at the LaTeX display and not the plaintext input: but when pressing enter, it will look nice. Redundant brackets are removed, including those that are needed for plaintext input (e.g. `(a + b)/(c + d)` can become "a + b" on the numerator and "c + d" on the denominator without brackets). * light/dark themes * previous input history can be accessed and edited by pressing "up" or "down" buttons. * previous inputs/vars/recently used units preserved when the app is closed * standard scientific calculator features, such as: * trigonometric functions: sin, cos, tan, arcsin, arccos, arctan * base 10 and natural logarithmic functions: log (base 10), ln (base e) * `e`, `pi` constants, and square root function * scientific notation input (e.g. `1.23E6` is 1.23 times 10^6)
Recent changes: Fix padding between variable names and values in "vars" popup. Fix "dated yet pricey" theme output display background to retro LCD colour. Add some settings to increase output display size on small screens: - option to increase the size of the output display, and - option to hide most or all buttons, instead relying mostly on the on-screen keyboard for text input.

Easy, simple, effective. Great calculator app to have handy!
★★★★★Derp Derpington· Mar 28, 2025
Absolutely fantastic, doesn't have any fluff, and does exactly what it advertises without the advertising part. If you want something that just works, this is it.

Strangely, it works for a day and then later - it doesn't work anymore. When I want to calculate something, after I hit enter, there is no answer.
