Time Zone Pro: World Clock

Time Zone Pro puts every city you care about on one screen, and moves them all with one finger.

Drag the slider on any card and every clock follows. "What time is it there if I call at 6?" takes a second instead of mental maths.

WHY TIME ZONE PRO
• One slider, every city. Drag any card's 24-hour scale and all your clocks move together.
• Read the day at a glance. Day cards are bright, night cards are dark, and each city shows whether it's before work, working, after work, night or the weekend.
• Numbers that feel alive. Digits change smoothly as you scrub, with a gentle tick every half hour.
• Arrange it your way. Long-press to wiggle the cards and drag them into the order you want.
• Accurate everywhere. Daylight saving time, half-hour and 45-minute offsets, and date changes are handled for you.
• Private by design. No account, no ads, no tracking and no location permission. Everything stays on your phone.
