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.

Quite literally the most pointless change to what was a decent working calculator - it is now utterly unuseable. It’s like a child’s speak and spell.

Once more pointless and unnecessary changes ruining a once great app.

why change it if it worked? It’s like it was designed by someone who never actually uses a calculator. 😡

There was a earlier threat about the in iOS 18 calculator a few weeks ago that some one posted and showed that calculator was inaccurate. I did the same on the Mac and it was correct.

Again, a single thread doesn't mean there is a problem with the Calculator app on that phone, let alone one an all phones. The vast majority of problems people have with phones, computers and tablets are the result of people not understanding how things work or making mistakes. And I include myself in that.


Did you test it on your iPhone?


ETA - The iPhone calculator is not wrong. The basic calculator only shows to one number after the decimal so it rounds. If you enter that calculation and switch to the scientific calculator, you'll see the two digits after the decimal.

There is an old saying “If it ain’t broke, don’t fix it”.


The iOS 17 calculator was definitely “not broken” (as evidenced by so many people griping about it — Me too). So Why did some genius? “fix it“?


Please make the iOS 17 calculator an option within your next revision … PLEASE.


Particularly, I enjoyed the basic calculator when my telephone is in the portrait position, but it automatically converted to the scientific calculator when I turned my phone to the landscape position. (Plus not ever having to hit the = between each set of numbers, to see my running total — no matter which calculator method I was using).


(Then, please stop Fixing things that don’t have a problem)

What I saw was for a current upgrade 18.1.1

I didn't say it wasn't. What I said was "iOS 18.1.1 didn't bring any changes that I'm aware of to Photos, Calendar or Calculator. All of the major changes were made with the release of iOS 18.0." What means is the Calculator is the same in iOS 18.1.1 as it was in 18.0.

Anyway I imagined the idea was to update with
the most current version so did not see a pre version.

Yes, you should do that. I never said otherwise. In fact, the response was directed at someone else entirely.

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 😀

I agree totally. I hate this change. I have to retype the entire equation every time. I wanted to enter $1000 and see what would happen if I got 12% interest over 40 years. Before, I only had to hit the enter button 40 times. Now I have to retype the entire calculation each time. Why fix something that’s not broken? This is not better at all. It’s actually worse.

I have what may be the answer: before iOS 18, there was a constant stream of complaints from users who said that if they accidentally hit “=“ twice they lost their calculation and the had to start over. So this change was in response to user requests.

I used the repeating “=“ operations to calculate compound interest over a few periods. No point of pulling up a separate tool or switching modes if you need to run it for 3 to 5 periods. I use this multiple times a day. Forced to download a different calculator and abandon the built-in one. Can we at least have a setting to control this behavior?
