What a 7 minutes timer is good for
Boiling eggs, a short break between tasks, a warm-up, a kid's clean-up sprint, or a quick meditation.
The countdown runs against your device clock, so it stays accurate if the tab is throttled in the background. At zero it fills the screen with a Stop button, plays your chosen sound, and vibrates on phones. Prefer a clock time instead? Use wake me up in 7 minutes.
