Looks great, works well, but . . .
In the preferences, you can select any set of cities you wish, and arrange those cities in any order you like.
In screensaver preferences, you can set it to "Explore my cities". But when it "explores", it visits them in some random order that it generates itself, spinning the globe back and forth - in both directions. I tried to solve that by arranging my cities in an east to west order, but screensaver mode ignores my preferred order of cities to bounce around in no apparent order at all. I find the result dizzying, distracting and disconcerting.
This app features a lovely rendering of earth; its purpose is to report on weather conditions. Programming it in a manner that plays fast and loose with the physics seems counter to its function, and undermines its credibility.
Correct those small design errors, and it would earn 5 stars, especially given the low price.
