Designing calculator apps

It is extremely weird that the calculator apps, even the default ones baked into desktop operating systems, embrace the UI and UX of those little cheap-o plastic physical calculators. I like what Florens Verschelde’s Math teacher had to say:

I had a Math teacher who would ban pocket calculators that didn’t show both your input and its result at the same time. If a calculator couldn’t show this:

38 ÷ 1.2
=    31.666666666667

You couldn’t use it.

The article ends up being in praise of Soulver, which I agree is a nice modern take on the idea of calculations.

I wish it was on Setapp, as I’d probably use it. But I don’t do enough regular mathin’ to go for the full price (today, anyway).
