Horzono World Clock & Daylight

Type a city and Horzono tells you what time it is there. You don't need to know its country, its capital, or its time zone — no time-zone math, no UTC in your head, no "wait, what time is it there?"

Add the people you work with and care about, and pick their city from 25,000+ of them. Give each one a name, an emoji, a photo, or a contact, because you're tracking people, not just cities. See their local time at a glance, and whether it's day or night where they are, so you know if it's a good moment to reach them. Drag the time-offset slider to preview any moment across everyone at once — find a time that works before you schedule a call, a meeting, or a trip.

Built for iPhone, iPad, the Mac menu bar, and Apple Vision Pro — with widgets on every one of them. Works completely offline with more than 25,000 cities. No ads. No tracking. No subscription.
