AllyClock

AllyClock turns your iPhone or iPad into the clock it deserves to be: a big, beautiful, fullscreen time display that looks great on a desk, a nightstand, or a shelf. Two faces, both live and adjustable: FULLSCREEN The time in large, thin digits with seconds ticking quietly beside them. Weekday, date, and time zone sit underneath on a clean baseline. Toggle seconds, weekday, zone, GMT offset, and the flag to make it yours. WORLD CARDS The cities you care about, each on its own card: flag, local time, date, and GMT offset. Add up to twelve cities, break them into rows, and scale the time and date independently. DESIGNED TO DISAPPEAR Controls fade away after a moment, leaving only the time. Tap anywhere to bring them back. Every change applies live: close a panel any way you like and your changes stick. MADE FOR LANDSCAPE AllyClock is built for iPhone and iPad in landscape, with a companion web version at allyclock.netlify.app.
