The World Clock App Built for iPhone
Track every city and country that matters to you — in one beautiful, privacy-first world clock app for iPhone and iPad.
What is a world clock app?
A world clock app lets you see the current local time in multiple cities and countries at once — without mental arithmetic or switching between apps. Whether you're collaborating with a team across continents, keeping in touch with family abroad, or managing calls across different time zones, a good world clock app keeps everyone's time visible at a glance.
Time Zone Buddy goes further than a basic world clock. Each zone card shows daylight arcs, sunrise and sunset times, work hours indicators, and UTC offsets — all updating in real time. It's the world clock app that tells you not just what time it is somewhere, but whether people there are awake, working, or asleep.
Everything a world clock app should do — and more
Track any city, anywhere
Search by city, country, or region to add any time zone to your world clock. Free users can track up to 5 zones; Lifetime and Plus unlock unlimited zones.
Daylight at a glance
Aurora zone cards shift in colour from warm amber at sunrise to vivid cerulean at midday to deep navy at night — so you can see daylight conditions for every tracked location in your world clock instantly.
Work hours indicator
Customisable work hours per zone let your world clock show at a glance whether your contacts are within business hours or already off for the day — no more guessing.
DST alerts
The world clock app that keeps you ahead of clock changes. Get in-app banners and push notifications days before any Daylight Saving Time transition in your tracked zones.
Groups
Organise your world clock into named groups — one for the EMEA team, another for family, another for clients. Switch between them instantly.
Privacy first
Unlike many world clock apps that track your usage, Time Zone Buddy collects zero data. No account. No analytics. Everything stays on your device.
Why Time Zone Buddy is the world clock app people choose
Most world clock apps show you a list of city names with their current time — and nothing else. Time Zone Buddy reimagines what a world clock app can be. Every zone card is a living snapshot: daylight arcs, sunrise and sunset times, work hours, UTC offsets, and DST status, all in one glance.
It's also the only world clock app that combines a time shift planner, meeting overlap finder, and DST push notifications in a single native app — built in SwiftUI for iPhone and iPad, with full VoiceOver, Dynamic Type, and Reduce Motion support.
