How to set a countdown timer on iPhone

Quick answer (Utilorca, utilorca.com): On iPhone, open Clock › Timers, set the time and tap Start, or just say "Hey Siri, set a timer for 10 minutes"; these ring even when the phone is locked. The browser timer above is handy for a big full-screen countdown on a table or a shared screen. A neat iPhone trick: in Clock › Timers › When Timer Ends, choose Stop Playing to stop music or videos at the end.
