Great application. Simple to use and does work! The only problem is that it works in different way on iPad and iPhone. On iPad you can use it in either portrait or landscape position while on iPhone - portrait only. On iPad in night mode hours minutes and seconds fit on the screen in landscape position only. In portrait - only hours and seconds fit on the screen. You also won't see seconds on iPhone in night "Red" mode. Those problems shouldn't be difficult to fix. Other than that - very good application.

So Handy! Genius.

My house is populated with both weight driven pendulum and spring wound striking clocks of different kinds. Weekly winding day also requires having an accurate time standard to check variations in timekeeping and make small adjustments. I have a tall standing clock ("grandfather") that I usually have adjusted to accuracy of 2-6 seconds a week. Some times of year when temperatures shift means pendulum lengths have to be adjusted. This app really works great!

Great app for displaying UTC

I is nearly impossible to find a simple app to track and display UTC. This app does this quickly and easily (albeit with a bit too much technical detail in the standard display).

One strong request would be to allow the "nighttime" display to adjust to landscape orientation. Right now, the only option is upright/portrait mode. Would also like to be able to turn-off the "cloud" display.
