About this app

The 12-hour world clock
(aka the Rotating-cities world clock)

The best watch available today, right on your phone or tablet
- about 100% accurate (if you sync your device with a time server, which is very easy, see Settings / Date & time / Automatic date & time)
- shows the time anywhere on the globe
- and it looks good too.

Highlights:
- world time at a glance
- stylish clock skins for your Android device: simple elegant (standard and silver), Big Ben clock, religious clock (christian, islamic and buddhist), flower clock, kitties clock, zodiac clock, snakes clock
- the app that turns your Android phone into a beautiful pocket watch
(and any older unused Android phone or tablet into a beautiful desk clock)
- for now the app is in English only
- it's been on Google Play for years now and nobody has ever complained about it, so it's as safe as can be
- optionally shown on the Android lock screen (recommended; note that it's not a lock screen wallpaper, it's an app that's over the lock screen, which means you can combine it with a wallpaper of your choice)
- works best as a pocket watch if you set your device to switch off automatically after 1 - 2 minutes of inactivity (which you should do anyway to save battery time) and set the app to be shown on the lock screen
- easiest way to personalize your phone or tablet, have some variety: just go to Clock appearance and change the clock style, and you're done
- the app that will make you think of all your friends around the globe
- whoever writes a positive review + rating receives an ads-free license for when I get to introduce ads / payed version

Important note: Unfortunately, due to changes in the OS, the lock screen feature doesn't work at all in Android 10, and has issues in 9. I'll fix this at some point, the new version should be ready in september.
-----------------------------------
This app is mainly a shortcut to a site that provides a 12-hour world clock.
This is an original design for a world clock, that features some 50 city names written on a normal (analog) 12-hour clock face, based on their time at any given moment. When the hour changes, the position of the towns on the clock face changes accordingly. Thus, the position on the clock face gives the time for each city. To distinguish between AM and PM time, a simple color scheme is used.
The fact that the clock face is a regular 12-hour one is novel. Up to this app there were (and still are) 24-hour world clocks in use, but obviously they're much more cumbersome.
See the online help http://intelnav.50webs.com/help.html for a detailed explanation of how it works.
The time shown by the clock is based on the system time and the time zone settings, which are taken over from the operating system but can be corrected by the user (usually that's not necessary).
-----------------------------------
This app is especially handy for seeing the world time on smartphones and tablets. You don't need to write the name of your chosen city in order to search for it in a lengthy list. Just tap on the app and you see the clock with the world's most representative 50 cities on it. Even if your display is a bit small, you can still rather quickly choose the zone on the clock face where your town of interest is located, and enlarge it to see the names at a proper size.
Of course, sometimes you're not sure what time zone your place of interest belongs to. To make things easy, this app provides time zones support, consisting of explanations and maps.
Bottom line, once you get used to the method, you will most likely find it handier than any other world clock app, especially on a mobile device.
-----------------------------------
There are 12 clock styles, they are listed in the Highlights section above and shown in the app entry's pictures. For most of them there's a dark face and a light face version.
Probably the best way to use the site as a pocket watch on Android is to display it on the lock screen (only possible from the app).
