Set an alarm

Pick a time and get an on-screen and audio alert when it arrives. Handy for coordinating a call in someone else's time zone.

Set minutes and seconds, then count down to zero with a clear on-screen display and alert sound.

Start, stop, and lap — a clean stopwatch with a running list of lap times.

Find the best meeting time across your team's time zones.
