I figured a couple of bucks was worth the risk to see if this clock was useful. It is, but only barely. It hasn’t been updated in a long time, so I am not terribly upset, but others might like to know: The time zone map is the one thing that works as it should—it’s a static map with the world’s time zones laid out in varying colors. It can be viewed wrapped around the globe or flat and can be zoomed, but the level of detail does not change The sun clock is pretty to look at but inaccurate: the sun does not rise at 06:00 in Seattle in November! No matter what date I choose, it insists on showing equal, 12-hour days and nights, as though summer and winter do not ever happen. The moon phases are also inaccurate, showing a waxing crescent when I can see a 98% nearly-full moon out if my window. There is supposed to be a transparency control on one screen, but I could not get it to work on iPadOS 13. So it’s deleted from my device. Unless this gets an update, save your coffee money for something else.
