AlexCalc vs Digital Calculator
Side-by-side comparison of two open source alternatives
AlexCalc
AlexCalc is a scientific calculator with some neat features (note: also available as a web app at https://alexbarry.github.io/AlexCalc/ ): 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)
Digital Calculator
A neumorphic themed digital calculator which has keyboard support (external bluetooth keyboard) and a few useful shortcuts for quick and easy access. It also has a dedicated dark theme (set based on system theme) for better accessibility. It is also supported by devices with the floating window feature and it also has a landscape mode.
