World Time Alarm Clock: TZ

Set an alarm for any city on Earth and wake on its local time. See both times at once, ring through lock, and never miss a call, meeting, or flight across zones.

World Clock Alarm is the simplest way to set an alarm for another time zone — and actually wake up on time, wherever "on time" is.

Pick a city anywhere in the world, set the alarm to its local time, and see both times side by side: the time THERE and the time HERE. No mental math. No 3 a.m. mistakes.

WHY PEOPLE USE IT • Travel & jet lag — wake on local time the moment you land • Remote & global teams — never miss a standup, handoff, or client call across zones • Family & friends abroad — call at a good hour for them, not a rude one for you • Markets & trading — catch the open in New York, London, or Tokyo • Live sports & events — set an alarm for kickoff in another country • Studying or working abroad — keep home and local schedules straight

BUILT TO ACTUALLY RING • Reliable, system-level alarms that go off even when your phone is locked or in your pocket • Full-screen wake-up with snooze, right on your lock screen • Snooze countdown at a glance on the lock screen and Dynamic Island • Automatic Daylight Saving Time — set it once, it stays correct
