TZ Tracker

Timezone Tracker keeps every city you care about on one screen, shows you the current time in each, and lets you set alarms in any of their time zones. Add a city and it appears in your list straight away. Tap any clock to set a time and every other city moves with it, so you can see that 9am Wednesday in New York is already Wednesday night in Tokyo without counting on your fingers. There's a slider if you'd rather scrub through the day than tap, and a Go Live button that snaps everything back to the current moment when you're done. ALARMS Set an alarm for 8am London time while you're sitting on the other side of the world, and it fires at the right moment no matter what your own clock says. One-time or daily. They still go off when the app is closed. WEATHER Each city's card shows the weather it's actually having: current temperature and conditions under an animated sky that runs from dawn to night on that city's own clock. If it's raining in London, it rains on the card. Snow, lightning, fog, and wind-blown leaves too. EVERYTHING ELSE • Search thousands of cities by name, country, state, or timezone abbreviation, with an online lookup for the obscure ones • Daylight saving is handled automatically, so the offsets are always right • Country flags and day/night skies, so you can tell at a glance where it's the middle of the night • 12-hour or 24-hour display, applied across the whole app • Card view or compact list, whichever suits you • Swipe to remove a city you no longer need • Light and dark themes for quick glances at any hour • Clocks and alarms work offline once installed. Weather tops itself up when you're online Useful if you're running meetings with a team spread across continents, calling family abroad, planning a trip, or just wondering whether it's a reasonable hour to text someone in Berlin. PRIVACY There's no sign-up and nothing to create an account for. Your saved cities and alarms are stored on your device and go nowhere else. Weather comes from the open Open-Meteo service, fetched anonymously with your saved cities' coordinates, never your device's location.
