Time Zone Alarm: UTC & World

Working across time zones? Set the alarm on the other city's clock — a 9:00 meeting in New York, the London open, a UTC on-call window — and your phone rings on time.

Time Zone Alarm sets an alarm on another city's clock. Pick the city, pick the time there, and your phone rings at the right moment here. No mental math, no missed meeting.

It is an alarm app first: every alarm is pegged to a time zone you choose, and it shows both times side by side — the time THERE and the time HERE — so you can see exactly when it will ring.

REMOTE WORK & MEETINGS ACROSS TIME ZONES Wake for a meeting scheduled in another office's time. Set 09:00 New York, 14:00 London, or 10:00 Singapore, repeat it on weekdays, and stop converting time zones in your head before every standup, handoff, or client call.

MARKETS & TRADING Catch the open from anywhere. 09:30 New York for the opening bell, 08:00 London, 09:00 Tokyo — set it once on weekdays and it fires on the market's clock, not yours.

UTC & ON-CALL Servers run on UTC. Put your on-call window, maintenance slot, or scheduled deploy on the zone it was actually planned in, and check it at a glance: every alarm shows its UTC offset, so what you set is what you meant.

FAMILY & FRIENDS ABROAD Ring yourself at a good hour for them, not a rude one for you — a weekly call home, a birthday, a school run six zones away.
