Questions About This Duration

What is a 12-minute timer best used for?
It is a strong fit for compact workouts, mobility, reading sprints and restorative breaks. Choose 15 minutes when you want setup, the main task and a short finish in one timer.
Is 12 minutes the right timer length for every task?
No. It is less suitable for maximum-effort exercise without warm-up or tasks that cannot stop cleanly. Match the timer to the task rather than choosing a duration only because it is familiar.
What timer should I use instead of 12 minutes?
Choose 15 minutes when you want setup, the main task and a short finish in one timer.
How is the remaining time calculated?
The countdown is driven by your device clock, so its display recalculates the remaining time whenever the browser is able to update. When the page is hidden the browser may slow the on-screen updates, but the finish time is calculated from the real clock. Background alarm sound is not guaranteed.
