Are iPhone timers accurate?

Is there a timer app that stays on screen iPhone?

I'd like to keep an eye on if my oven is preheating or cooking because my family will be arriving momentarily.

I've been using the home app, but this seems to be an ongoing screen. Is there something I could do that would show how long until we would need to start cooking or how much longer it's been?

No. However, you can make an app for iOS and use Siri to trigger its launch. I use it like this: 1) open timer 2) set timer to cook and 3) then say "start cooking" or "start heating." The same works for "stop cooking/heating." 4) Once the timer app starts (after 30 seconds), it counts down and turns yellow until you say the command.

Does iPhone have a timer app?

I would like to build an app for my company that would tell us how much time we are spending in different applications.

I know the iPhone does not have this built in, but I was wondering if anyone has a link to any apps that would help me out? I am more looking for the simple timer app that you can play a sound at X minutes, X hours, etc.

There is no such thing as a "simple timer". I know this sounds dumb, but I will explain. When you want to use a timer, you need to go through steps to set a timer, stop a timer, etc. This takes time. It's important that your user understands how to use your timer feature.

Then when you think of a "timer", what do you think of? A clock with an arrow that moves around. Well, the only app that comes to mind is the Timer (iTunes) app, and it is just a basic clock that makes a sound after every interval.

It doesn't take much time to explain how to set a timer, stop a timer, etc. But it might take a while to build an app that can do that. And if you want to add other features to your timer, it gets complicated.

But, with all that being said, there are plenty of timers available for the iPhone. The easiest one is called 1-Minute, but it is more for counting out every 1 minute rather than a timer.

What is the app that sets multiple timers on iPhone?

I'd like to be able to set them all, and then be able to disable/pause them.

Is there an app for this? Or can I use multiple NSTimer objects and pause/resume them?

Look into MPTimer. You set up one or more Timers (either by creating a NSObject that conforms to the NSCalendarTimerDelegate Protocol, or a class-level implementation), and then tell MPTimer to fire it with -startAtDate:calendar:timeZone:repeats:. It sounds like you're going to need more than one timer though -- so you can create a NSCalendar object that is shared between all your timers (say, using a static dictionary).

Are iPhone timers accurate?

We found that the iPhone's "timer" doesn't seem to be that precise (a couple of seconds off). The way I tested it was to use an app timer (Clockify), which displays the timer in the status bar and makes it a pain to use the phone.

Is there a better way to find out if a device's timer is accurate? How many clock changes have you done per day, per week, per month? Why is it that Apple is so accurate at tracking time, and every other brand on the market is way off? You are saying that because the device uses NTP, that it should be way more accurate than an Android device? I guess it does have something to do with Apple using it's own servers and sending your location to their database - but that also seems pretty crazy. If you are looking to just get the number of seconds since Jan 1, 2025, using the NTP servers and then converting to Unix Epoch time in a batch process is really, really easy (using the shell script below). The main reason why people need to know their own time accurately is for military purposes. I'm not even sure how accurate it is in a civilian context. Most other things are more important than military precision.

I would think that the time being recorded in a smartphone, while it might be accurate from one day to the next, would be completely inaccurate over several months as a result of the battery running down.
