Frequently Asked Questions
Will the timer ring if I switch tabs?
Yes. The time keeps running in the background and the alarm goes off at the end, even if the tab is no longer visible.
How do I count the days between two dates?
Use the "Date calculator": it gives the number of days, weeks and months between two dates, or the date you get by adding a duration.
Can I show the timer in large format?
Yes. The timers and the clock have a full-screen mode, handy in class, in meetings or for workouts.
