About this app

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)

Ratings and reviews

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.

Saw your post online, this is great! Very intuitive and I love the lack of ads.

Easy, simple, effective. Great calculator app to have handy!

What’s new

* Add cube root button
* Add some new colour schemes
* Add units h, Wh, and Whr (previously could only do "W hr")
* Add haptic feedback
* fix "clear scrn" button that wasn't clearing the output display in Android
