Very useful and beautiful

I’m glad that I discovered this about two weeks ago. It is very useful to quickly verify Times world-wide before I want to contact friends, it may be too early or too late.

Too many people are ruthless and easily use hurtful words when they don’t like things. I am sure they are in the minority.

Many have their sounds on I enjoy the neon multi colors. It soothes the artistic right side of the brain. It is so useful to just spin it quickly and find my previous pin. I like the quick zoom in out. It has an interesting night/shade transition. I like the option to show the country boundaries. Of the two maps, I favor the vertical latitude color slices over the blue ocean.

Suggested improvement/requirements:

1. Play with the font size and colors to give us a clearer view to read the names, County, and temperature. Perhaps let us cycle through options and please include one that has ALL the characters black or white, that might work best.

2. The third row of information on a pin is too small to read on my iPhone 6. Yes you can zoom, but when you select the zoom for the name and time, the third line is too small. Make them the same size If you keep the same rectangle width, have the third line go into a fourth line.

3. Perhaps give us the option to turn off the background color to the names/times rectangle board that is supposed to improve the view of the selected point, but that color doesn’t look good and it detracts. That may lesson the cluttered look.

4. Give us a few more brighter color options with the world color latitude slices. For me the are on the darker side of the spectrum. I throng a beige may be good, and others that at just more cheerful.

5. Adding a slider for sensitivity increase or decrease when using the thumb to rotate would help.

6. Consider grouping all the user interface menu together for a cleaner look.

Thanks. You have a great idea. I know that with future updates it will continue to be so useful. I’ll increase stars when a couple of additions are made. You already have a 10/10 app. Just like the picture rings, this model helps us see so much in an instant.

Wish you and your team (maybe it’s just you!) and the world safety.

Pretty cool app

Pretty fun interface too, once you take the time to understand it. I really like the design concept of showing selected times on a globe. For quick reference, it is probably not the most efficient time application, but the logic of presenting times on a rotatable, resizable earth globe hooked me.

This is 20% finished

I am the average modern person with friends all over the world, in 10 different time zones and business in 4. This is not the app I want to use for easily checking who is awake. Developer: 请你看纽约地铁地图为了解怎么表示非常复杂的内容但是都很容易立刻明白。这是你的唯一目的:表示无论什么细节与全球时区有关,并且仅显示某用户感兴趣的内容。我对法国三流城市一切无所谓,在哪儿没有任何联系。如果只有我的朋友的居住城市名次和标记图示、并在城市名次下面应该放当前当地几点,天气和温度,依我看,该下面信息的字体大小只好与城市名词相比更小,60%左右。以外该信息一点也没有。在分享信息来说,请你避免中国的大风风格啊!越少越好!只有放熟悉城市,就能小化你的软件窗户又随手设计非常美丽的小部件。当然可能保持旋转地球仪在小化版。请你联系我。
