The world clock app built for iPhone.

Track as many time zones as you need, see daylight and work hours at a glance, find the perfect meeting window across continents, and get notified before every clock change — all on your device, with no personal data collected.

Daylight-aware zone cards in light mode shifting colour with the daylight in each city

Time zones that come alive.

Zone cards shift from warm amber at sunrise to vivid cerulean at midday — and deep navy at night. In real time, for every zone you're watching.

Plan any time, from anywhere.

Drag the time-shift bar ±12 hours, pick a future date, and instantly see the clock in every zone. No calculator, no guessing.

Meeting Overlap results ranking the best meeting window across time zones

The perfect meeting window, found.

Meeting Overlap ranks every possible overlap window by how many people it works for. Share the result as a clean image — no app required on their end.

Never miss a clock change.

DST alerts appear in-app the week before a transition, with optional push notifications at 7 days out, the business day before, and the morning it happens.

iPhone Home Screen with Time Zone Buddy Single Zone and Multi-City widgets shaded by live daylight

The world, on your Home Screen.

The free Single Zone widget keeps any city's live time on your Home Screen in small or medium size, with the same daylight-aware shading as the app — the medium size adds a day timeline and an at-a-glance work-hours status. Lifetime and Plus add Lock Screen clocks and a live Meeting Hub widget showing who's working right now across all your zones.

Right where you need it.

Long-press the app icon to plan a meeting, add a zone, or jump straight to alerts. Ask Siri or use the Shortcuts app: “Plan a meeting in Time Zone Buddy.”

Spotlight indexes every zone you've saved with its country flag, region, UTC offset, and both abbreviations — search EST, EDT, AEST, or AEDT any time of year and the right zone surfaces. Tap to open it instantly.

Built for Apple, end to end.

A native SwiftUI app for iPhone and iPad. Liquid Glass surfaces, App Intents, Siri, Spotlight, Quick Actions, the Share Sheet, iCloud Sync, full VoiceOver and Dynamic Type support, and Reduce Motion respect — it feels like Apple shipped it.

Frequently asked questions

Up to 5 time zones, the full daylight-aware zone card display (including daylight, sunrise/sunset, and work hours), the time-shift planner, and the free Single Zone Home Screen widget (small & medium). Ads are shown on the home and detail screens. Groups, Meeting Overlap, Lock Screen & Meeting Hub widgets, DST alerts, public holidays, notifications, and exports require Lifetime or Plus.
Yes. The Lifetime option ($39.99 AUD) unlocks everything except iCloud Sync with a single purchase. No subscription, no renewal. You keep all current features forever on iOS and iPadOS.
iCloud Sync is an active, continuously running service — it keeps your zones and groups in sync across your supported Apple devices. Because it requires ongoing maintenance, it's the one feature that honestly belongs with a subscription. Everything else is a one-time unlock.
iCloud Sync (your zones appear instantly on every supported Apple device you own), Family Sharing with the Annual plan (up to 5 family members), and early access to new features. If iCloud Sync or Family Sharing matters to you, Plus Annual is the right choice. If you prefer owning your software outright, Lifetime is the better deal.
Yes — the Annual plan includes Family Sharing for up to 5 family members via App Store Family Sharing. The Monthly plan does not include Family Sharing. Lifetime does not include Family Sharing.
Yes. Your time zones, groups, and settings never leave your device — there are no accounts and no servers of our own. The app uses only anonymous, aggregate analytics (via Firebase) to understand which features are used; it is never linked to your identity and never sold. If you enable iCloud Sync (Plus only), your data is stored in your personal iCloud account — not ours. We never see it.
When a tracked timezone has an upcoming daylight saving change within 7 days, a banner appears at the top of the Home screen (Lifetime/Plus only). If you enable notifications, you'll receive push alerts at 7 days before, the business day before, the morning of the change, and the day after — all scheduled on-device.
Meeting Overlap finds the best time window to meet across any number of timezones. It calculates which time slots overlap with the work hours of the most people in your tracked zones, ranks them, and shows local times for each zone. Share the result as a clean image or text. Requires Lifetime or Plus.
Yes. Three App Shortcuts ship with the app and appear automatically in Siri, Spotlight, and the Shortcuts app: “Plan a meeting in Time Zone Buddy”, “Add a time zone in Time Zone Buddy”, and “Show alerts in Time Zone Buddy”. Long-pressing the Home Screen icon exposes the same three Quick Actions. Saved zones are indexed in Spotlight with their country flag, region, UTC offset, and both standard and DST abbreviations — search EST, EDT, AEST, or AEDT any time of year and the right zone surfaces. Tap a result to open the zone instantly.
Open Time Zone Buddy → Settings → Restore Purchases. Your Lifetime or Plus subscription will be restored automatically using your Apple ID.
Yes. The Single Zone widget is free and comes in small and medium sizes — it shows any saved city’s live time with the same daylight-aware shading as the app, and the medium size adds a day timeline and a work-hours status line with the next start or finish time. Lifetime and Plus add Lock Screen clocks (circular, inline, and rectangular accessory widgets) and the Meeting Hub widget (small, medium, and large) that shows who’s in work hours right now across all your zones, who’s coming online soon, and who’s off duty. Tap any widget to jump straight into the app. Widgets read your data on-device through a private App Group — nothing leaves your device.
