World ClockTime Zones provides you with access to the time in cities all over the world, and you can save your favorites to a main list. Various search features make it easy to find the cities you're looking for, and the app's intuitive interface contributes to an overall positive user experience.
The first time you open World ClockTime Zones, you'll see a list of a few preloaded cities from around the world, along with the flags of their respective countries, and the current time there. Tapping any of these cities will take you to a more detailed view, which includes a little more information about the city, a link to see it on a map, and a description of how its time zone relates to UTC and your own time zone. You can add other cities to this list by tapping the + icon in the top left-hand corner of the screen and either typing a city name in the search box or scrolling through the alphabetized list.
There is also a time zone map and a time zone converter feature that you can use if you upgrade to the premium version for $1.99. And the World Clock tab displays all cities with the current time listed next to them in a searchable or scrollable list. This app works well and has a nice assortment of features, so if you need to know the time in multiple cities on a regular basis, this is a good tool to have in your arsenal.
