How to make iPhone/Siri start timing? I want to start a stopwatch to time how long something takes. There are many posts on count down timers (a.k.a egg timer) but none cover a way to start a count-up timer (a.k.a stopwatch) using Siri voice command.
I suspect not, based on all answers to this related question don’t answer the core question of automation + count up.

I prefer to not jailbreak the OS
Native solution is preferred
I’m open to third party apps if needed
I’m open to python or other scripting language or framework if that is “the only way”

Is there any way to achieve this, perhaps via scriptable?
To start a countdown timer, simply say: &quot;Hey Siri, set a timer for [hours][minutes][seconds]&quot;
Example: Hey Siri, set a timer for three hours, 12 minutes and 52 seconds.
The upper limit on timers is 24 hours, and you can have only one timer running on iPhone (HomePod allows multiple named count down timers now).

You can ask Siri how much time is left on the timer by asking Hey Siri, how much time is left on the timer?
You can stop the timer by saying Hey Siri, stop the timer.

There's no native way for Siri to start a stopwatch / count up timer, unfortunately, except through the UI.
