But iPadOS still lacks a native calculator. The only computer that does?

There are a billion calculator apps on the App Store. Admittedly that requires expending 8-12 calories to tap on a button to install the app, and consumes 5 seconds of your day that could be spent on more important things.


your attitude is hilarious, considering you just defended apple touting globally that the ipad is a laptop "replacement" that has not had real mouse support until...somewhere around a month ago (accessibility mouse support at ios 13 launch is not mouse support).

until it split off into iPadOS it existed with iOS which did have a calculator.

apple that claims making apps for any device and iOS version is super simple with their xcode tools, and can have apps properly sized because of their super simple xcode tools, could not do the same thing with their calculator app for iPad?

iPad that should replace laptops could not have a calculator, while their *mobile phones* can, their desktop OS can (and does. speaking of, how about that super special catalyst software for app parity between ipad and macos? no calculator that way?) and Windows can?

but you *really* want to snark someone about how they can go get one of "a billion" calculator apps from the app store that had about 1.8 million apps total as of this year? your hyperbole is so extreme it's childish.

nice try. where's the damn calculator app?
