Calculator App Issues in iOS 18

Is anyone at Apple addressing the issues with the iOS 18 calculator app on iPhone? Pressing equal after entering an equation and solving at once doesn’t allow you to calculate again without retyping everything. I use the calculator multiple times a week as a counter at work and losing this functionality is incredibly impactful.


I’ve also found that the calculator will move to scientific notation in the six figure range in vertical mode. This seems excessive, considering the old calculator would display millions without switching to scientific notation. I’m really confused why these “features” were added to the new calculator as opposed to leaving actual working features from before.

Just downloaded PCalc, per this recommendation, since it’s an app you have to pay for, I bought it(as I refuse to pay a monthly subscription for pretty much anything(like some of the third party calculators want) a one time purchase was a good option. At first I freaked out because the equal wouldn’t repeat the operation, but luckily, it’s just a setting in its gear menu, and now I once again have a functional calculator. I think it’s ridiculous that apple would throw away basic functionality, but at least I can have a useable calculator now. Thanks Idris!


the more I dig into PCalcs features the more awesome it seems. When you click the 42 button (awesome reference) it has mathematical constants for all sorts of fields. Like it’s fully functional for my purposes, but I can also just geek out with it for awhile too, and figure out things I have no direct need to for fun 😀

There are hundreds of calculators, and they all work differently from each other. So it is meaningless to say anything about “how calculators have worked for 50 years”. I’ve been using calculators for more than 50 years, from Frieden mechanical for solving engineering problems, to a Sony with a Nixie display that could do square roots, to the HP-35 (the first scientific calculator), over many others to the HP-12C, a model that was first introduced in 1981, is still in production and is regarded by many as the best calculator ever developed. I have 3 located in different workspaces, as well as an emulator on my iPhone and iPad. In addition I have several calculators both hardware and on iPhone emulations, because each has features that I want at different times. And yes, I have a calculator with a real paper tape.


So cut the nonsense on “how calculators have worked for 50 years.” And BTW, the latest Apple calculator was updated to meet the requests of many users over many years.


Here are my earliest calculators (the yellow one is the same model carried by US astronauts on Space Shuttle missions, the one on the left was used by my stepfather when he designed the human centrifuge for NASA):

The Calculator app on the Mac (or iPhone) is not fifty years old. Tim Cook, who currently helms Apple, is, in fact, part of the Baby Boom generation. Not that I subscribe to this nonsense that everyone born between certain years behaves in certain ways.
