Shadowline: World Time Zones
Meeting planner & Jet Lag tool
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Shadowline turns time zones into something you can actually see.
Track the cities that matter to you, then read them at a glance — as elegant clock faces, or on a single 24-hour dial where every city sits on one ring so you instantly see who's awake, who's asleep, and the hours you overlap.
FEATURES
• World clocks — Add any city on Earth and see its time, day or night, and offset from you. Reorder, rename, and theme each one.
• 24-hour dial — All your cities on one circular timeline. Drag to scrub through the day and find a time that works everywhere.
• Meeting planner — Swipe through upcoming hours and watch every city update together. Found a slot? Add it straight to your calendar.
• JetLag IQ — Heading somewhere new? Get a simple, science-based plan to shift your body clock and land ready.
• Day & night map — A live world map with the real sunlight terminator, plus sunrise, sunset, and moon phase.
• Widgets — Put your favorite cities and the dial on your Home and Lock Screen in styles that match your look.
Everything runs entirely on your device. No account, no ads, no tracking — your cities and settings never leave your phone.
SHADOWLINE PRO
Free to use with up to three cities. Unlock Shadowline Pro once — a single $2.49 purchase, no subscription — for unlimited cities, every widget style, and import/export. Yours forever.
