A nifty little trick from Dr. Drang that gives you, functionally, multiple timers on iOS and HomePod:
In iOS, the timer function is in the Clock app, and there’s only one. There’s no way to have two timers running simultaneously and no way to give your timer a name that lets you know what it’s for.
But you do have Reminders. They have names and can be set to alarm not only at an absolute time, but also at a relative time:
“Hey Siri, remind me to check the casserole in 20 minutes.”
For this to work on HomePod, you’ll have to enable personal requests, which is kind of lame. But at least there’s a simple workaround with a relatively natural syntax.
