All cities' times change automatically just by scrolling it with your finger.
Therefore, you don't need to add or subtract times any more to calculate time differences.

-You can change the time with a unit for one hour by the double-tap of Time Bar.
-Tap the name of the city to set the date and time in that location.
-Choose your favorite cities from a list of available cities in the application.

Please note that we are not liable whatsoever for any profit loss, or any other form of loss experienced by the customer from using this application.

※We don't have any time difference data in our app.
We have been inquiring about time differences of each city to iOS.
Therefore, “World Clock” shows you the time of iOS.
As a result, depending on the version of iOS you are using, the exact time may not be displayed.
If you find a time lag in our app, please confirm default "Clock" app on your iPhone.
If the time in "Clock" app is the same with the time in our “World Clock”, it means that our app is running normally.

※Abbreviated name of time zone was originally researched and added.
If you notice any mistakes, please contact us from the support site.

Exactly what I want

Works so well. Excellent app.

Very limited city choices.

Extremely limited city choices, especially internationally. Makes it very difficult to rely upon this app because a lot of times you just have to guess what city is nearby. Also a lot of major US cities you would expect to be there are not. Overall a nice interface, but the development team refuses to update their database despite numerous requests. Stating some sort of ridiculous limitation, Which in reality is no more complex than adding city pairs and time zones to a database. Don’t waste your time here, there are many others that are better.
