Numi is not limited to simple calculations, it can solve expressions of any complexity, with parentheses, mathematical operations and high accuracy (up to 38 mantissa digits).
- Units: Numi supports currency, length, area, volume, time, temperature, css and data size conversion. It also allows to use dates in arithmetics.
- Variables & tokens: Numi allows to reuse calculations by using variables. By using special variables (tokens) like sum or average, it is possible to automatically calculate the sum or average value for all previous results
Percentages. Numi allows to calculate not just a percent of a value, but different percentage situation, like 5% of what is 20 cm or 15% on $20
- Time zones: You can easily convert time between time zones and get current time in different locations like Seoul time or now in Germany.
- Numeral systems: It is possible to use numbers in binary, octal or hexadecimal form using appropriate prefix: 0b, 0o and 0x. You can change output as well.
- CSS: You can make some CSS computations and conversions.
- Math functions: Numi support variety of math functions, like sin, cos, exponent, root, log, factorial, rounding and many others.
In order to extend Numi functionality you can use Numi plugin kit to develop and distribute your own plugins.

Said about Numi as an alternative
It has similar "natural" describing for calculations. Spreadsheet-like functions, instant answers, variables, conversions etc. It's all here. Like a (powerful) sub-set of Calca.

My favorite, despite small glitches in complex formulas and a stalled development.
A handy calculator that lives on my Mac menubar. It's ok but there are some pretty annoying issues:
When you type * for multiplication, it auto-translates it to a graphical X. However, if you type the character x/X because it's subliminally suggesting to you, it doesn't' recognize it as multiplication.
You can't type any label with a number in a line without it being confused if it's part of the calculation. So if I type ESP32 as a name, 32 becomes part of the math.
But its handiness is very helpful. I prefer Soulvr for calucation and conversion, etc. but it doesn't live in the menubar, which is a drawback.
