Yes, this is why the default iPhone calculator app is completely useless.

These forced animations make tasks take the same amount of time regardless of how fast the hardware gets. I would love to be able to turn off all animations in iphone/ipad UIs.

Probably that's the reason there isn't one on iPad. Let that sink in. There's no calculator on a $1000+ 'Pro' device.

Let what sink in? There are plenty of better third party calculators available than the system calc on iPhone. So much of the angst and frustration comes from self-imposed rules on what is acceptable rather than calmly finding solutions.

Maybe I'm misunderstanding the problem being described, but I just tried this and it is impossible for me to type so fast in the iphone calculator app that it misses inputs. The animation completes in the background but does not block anything.

If I type "3 + 6 + 9" as fast as I can, then hit "=", I only get 18 about half the time. Sometimes I get 12, sometimes 15, occasionally something else. This is with a iPhone 11 Pro on iOS 14.4.2. It's ridiculous. I always hear the same number of clicks, though.

I must have never run into this because I don't calculate fast enough, but I just tried it and confirmed it really happens.

Somehow got the "6" key is stuck lit up, and despite having definitely registered a tap, it wasn't included in the addition.

That is extremely strange. Weighing in from an iPhone XS here on the latest iOS, I cannot understand how it is humanly possible to type the numbers fast enough they aren't picked up. I just tried to do it, pressing 3+6+9= as fast as I could, and I could not manage to get it to not detect my taps. I wonder if you have a defective screen? I have no other explanation

Just tested this a few times on an XS Max 14.4.2 and got 18 every time.

Happens to me all the time, especially when repeating the same numbers.

Well, it's already made pretty useless by not showing you what's it's calculating…

right. it's even more frustrating in light of the amazing advances in parallel processing for these devices over the years, which are essentially being ignored. at the very least, they could offload the animation to secondary threads/processes and unblock the i/o, which would allow the keypresses to be registered correctly even as you wait for the UI to catch up. instead, you're forced to wait for the animation to finish before registering the next input.

the computer should serve the whims of the user, not the other way around.

There used to be a jailbreak tweak called Accelerate that would speed up animations.

I still use an iPhone 4S, and thanks to this tweak, I don't feel like my phone is any slower than newer models. Pity I can't browse half the web though (https died due to TLS).

You can. Settings -> Accessibility -> Motion -> Reduce Motion

Workaround. It should capture the touches and send it anyway. Like on macOS for example

It's not perfect though, and it only makes the OS marginally more snappy since it replaces many animations with equally slow fades.

That setting only changes the moving animations into fades but doesn't actually make anything faster.

Animations still take the same amount of time blocking interactivity.
