It sounds like a gimmick at first, but looks surprisingly useful. I'd surely install it if it was available as an app to use alongside my usual calculator, and while I cannot quite recall a situation when I needed it, it seems very plausible that I'll start finding use cases once I have it bound to some hotkey on my keyboard.
I just threw numbers into there (population x ownership percent x replacement frequency x unit cost) to estimate the annual revenue of the smartphone market and got a few percentage points away from what the internet reports is the true value.
Because there are trig functions, this would also be nice for reverse engineering of complex parts from simple measurements (feature volumes, corner angles, cross-sectional areas)
Multimodal would be nice but not necessary.
Inverse trig functions would be interesting but complicated and not necessary.
In any case, this tool is more convenient than opening Python every time I want to estimate a range of answers.

They use dart as their primary language so it should be easy to make a flutter app from it...
