The Time Zone App That Does It All
Convert times across every city, plan meetings across continents, and never miss a Daylight Saving Time change — all in one time zone app for iPhone and iPad.
What makes a great time zone app?
A time zone converter lets you answer one simple question: "If it's 3 pm here, what time is it there?" Most time zone apps stop there. Time Zone Buddy goes much further — it shows you not just the converted time, but whether it's daylight, whether people are working, and how the time difference shifts on a future date when DST changes.
Think of it as a time zone app, a time zone converter, a meeting planner, and a DST tracker — all rolled into one beautifully designed, privacy-first app for Apple devices.
Time zone conversion, the smart way
Time Shift Planner
Drag the time-shift bar ±12 hours, pick any future date, and instantly see the converted time in every tracked zone simultaneously. The fastest time zone converter on iPhone.
Meeting Overlap Finder
The time zone app that finds the best meeting window for you. Meeting Overlap ranks every possible time slot by how many team members' work hours it covers, then shows local times for every zone — shareable as an image.
DST-aware conversion
Your time zone converter automatically accounts for Daylight Saving Time transitions on any date you pick. No more manual adjustments when the clocks change.
All zones, all at once
Unlike web-based time zone converters that only handle two zones at a time, this time zone app shows you converted times for every city you track — in a single screen.
Spotlight & Siri integration
Search EST, AEST, or any timezone abbreviation in Spotlight and Time Zone Buddy surfaces the right zone instantly. Ask Siri to plan a meeting — no app switching required.
No data collected
Your time zone conversions stay on your device. No account required, no analytics, no servers. The time zone app that respects your privacy completely.
Who uses this time zone app?
Remote & distributed teams
Plan standups and reviews without the mental overhead of time zone maths. Use the Meeting Overlap finder to identify windows that actually work for Sydney, London, and New York simultaneously.
Frequent travellers
Keep your home time zone alongside your destination. Drag the time-shift bar to see what time it'll be back home when you land, or whether it's too late to call.
Families living apart
Know at a glance whether your family overseas is asleep, at work, or free for a video call — without doing the arithmetic every time.
Anyone who hates DST surprises
DST alerts warn you up to 7 days before any clock change in your tracked zones, so a meeting you scheduled months ago doesn't suddenly shift by an hour.
