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.

Mi ne eĉ vidas metodon por selekti lingvon. La listo en la reklamo ne eĉ montras esperanton! ### 3/5 — no support for UTC only locations *2026-02-02* really wish I had the ability to add UTC zulu as a reference time without having to pick a specific city ### 5/5 — Very useful! *2026-01-14, version 2.0.3* Sliding feature is the best! Would be nice to slide 24hrs instead of only 12hrs. ### 5/5 — Works great! *2026-01-14, version 2.0.2* Sliding feature is the best! Would be nice to slide 24hrs instead of only 12hrs. ### 1/5 — Not working *2025-12-23, version 2.0.2* This app is always frozen right after you buy it ### 4/5 — Not quite what I needed *2024-12-26* Needs: * 12hr/24hr time format toggle in settings (currently follows system settings) * Time slider needs to do more. - Current can only shift time up to 12 hrs in the future - Plus or minus 12 hrs is what I need. ### 5/5 — Great app *2024-05-21* Great app! I love how I can set a primary city and quickly compare other time zones to it. ### 5/5 — Easy! *2024-05-21* Horzono's interface is clean and intuitive. It's so easy to navigate and use. ### 5/5 — Great. *2024-05-20* The ability to use this app offline is just amazing. Helps a lot when I'm in areas with poor internet connectivity. ### 5/5 — Awesome app. *2024-05-20* This app is a lifesaver for scheduling my international calls.

Calls more than 30 minutes out are left alone, and when there is nothing to join, Horzono says so instead of doing nothing. • iPhone and iPad: the time-offset slider no longer stops responding to drags until you relaunch the app. • iCloud: turning sync on or off now closes the previous database before opening the new one, and no longer listens for remote changes before it is ready.

Tap one to open that location in the app. • Made for iPad — a two-column layout puts the calendar and your events beside a grid of everyone you track, and reflows to any width, Split View included. • 12- or 24-hour clock — choose the format in Settings, or keep following the system. • Group by time zone — everyone in the same zone collapses into one row, labeled CET, EST, and so on. (Horzono Plus) • Attach people to a location — add several contacts to one city and see their faces on the row and in your widgets. (Horzono Plus) • MCP server on Mac — let Claude and other AI assistants read the people you track, their local time and daylight, and find a meeting time that works for everyone.
