Meridiem is a world clock built for people who live across time zones — remote teams, long-distance relationships, frequent travelers, and anyone who needs to know what time it is somewhere else, at a glance. See the whole picture on a living 3D globe that tracks day and night in real time, with every city you follow pinned right where it belongs. Switch to Timeline to compare hours side by side, and let Golden Hour do the math for you — it automatically finds the best overlapping window to call, meet, or message someone in a different time zone. FEATURES - Interactive 3D globe with a real-time day/night terminator - Golden Hour: automatically finds the best time to connect across every city you track - Add any city in seconds, with smart matches for lesser-known places (search "Alaska" and Adak shows up; search "Guadalajara" and Mexico City appears, since they share a zone) - Fully customizable list — reorder or remove any city, including the ones Meridiem starts you with - A clean, calm, distraction-free design PRIVATE BY DESIGN Meridiem doesn't ask for your location, doesn't require an account, and doesn't connect to the internet at all. "You" is simply your iPhone's own time zone setting. There's no tracking, no analytics, and nothing about you ever leaves your device. Whether you're just curious what time it is in Tokyo right now, keeping up with family abroad, or coordinating with a team across three continents, Meridiem makes time zones feel simple again.
