Horzono 3.0 is here — now in 11 languages, with calendar events and a busy-day heat map. See daylight across the world, plan meetings, and scrub time across every city.
Horzono is the fastest way to keep track of time around the world — and the only world clock that shows you daylight and night for every city at a glance.
Add the places you care about and instantly see each one's local time, the difference from your reference city, and whether it's currently day or night. Drag the time-offset slider to preview any moment across every location at once — perfect for scheduling international calls, planning meetings, and coordinating travel.
Built for iPhone, iPad, the Mac menu bar, and Apple Vision Pro. Works completely offline with more than 25,000 cities. No ads. No tracking. No subscription.
