ZoneVsZone

ZoneVsZone is a handy way to visualize 24 hours of time in different time zones.

It's usually easy to figure out what time it is right now in a different time zone, and lots of clocks do that.
But it can get confusing when you're thinking 4, 6, 14 hour ahead, particularly when trying to remember if it will be AM or PM then.

ZoneVsZone gives you a handy way to see a full 24 hours of one time zone against another time zone. Running your finger up and down the time list enlarges each hour making things easier to read.

Time zones default to UTC and your local zone. Tap the Info button to get to settings, allowing you to choose the time zone for the left and right side of the clock. You can also set 12 vs. 24 hour time display.
You can also change the text and background colors. Version 1.2.1 adds a setting to speak the time as you tap or swipe.
Version 1.2.2 adds font picking, customize your view!
