Cities lets you travel the world to see what time it was, is or will be for any city on any date or time, from the perspective of any timezone (including the one you’re currently in).
To change the date or time, simply use the date and time picker at the bottom of the screen. All the cities listed will move relative to the date and time you have set. This lets you work out things like “what time will it be in Detroit if I'm in Melbourne next Wednesday at 23:15?” or “if it’s 10 AM in Miami, what time is it in Dubai?”.
Tapping Now will return you to today at the current time.

You can have as many cities as you like listed to compare. Tap + to add a city. From the Add A City screen, start typing the name of the city you’d like to add, then tap on its name when it appears.
Tip: you can also search for country names.

In the highly unlikely event that the city you’re after isn’t in our database, you can add a custom city. To do this, tap Custom from the Add A City screen, then enter the city name, country name and timezone.
If you’d like the city to be added to Cities in the next release, then check the “Send this city to Bjango so it can be included in future versions” option. This will send us the details you’ve just entered when you tap Save.
Tap Save when you’re done.

To delete a city from the list, tap Edit then the (-) icon next to the city you’d like to delete, then Delete. Reordering cities can be done with the handle on the right hand side of the city name when in the edit mode.
Tip: you can also swipe from left to right then tap Delete to remove a city.
When you’ve finished editing, tap Done.

24-hour time — If on, Cities will use 24-hour times (13:45 etc) throughout the application. If off, Cities will use 12-hour times (1:45 PM etc).
Custom Timezone — Normally Cities will use the timezone and time you have your iPhone set to. If you’d like to use a different timezone, then enable this option and set a timezone below.
Timezone — When Custom Timezone is turned on, this timezone will be used to calculate all the other times. This means you could be in Paris, but set Timezone to New York and turn Custom Timezone on to see all city times from the perspective of New York.
