This is a simple app that allows users to see what time it is (or will be) across multiple timezones. Absolutely essential for arranging conference calls across multiple time zones. The screen displays four time pickers - the top one is the user's local time and the other three display the time for user selected time zones. Changing the time in any of the time zones automatically sets the time in all the others. The top city is always set to the phone's local time zone. The user can select the other cities / time zones by pressing the name of the city and selecting a new city / zone in the search dialog. Alternatively the Settings button will take the use to the standard iPhone settings screen. The "Now" button sets the time pickers to the current time and also updates any changes to the user selected time zones in the iPhone app settings.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Time Zone Calculator holds the better App Store score, 3.2 against 3.0. Both are backed by a comparable volume of ratings — 6 and 2 respectively. Written reviews complicate that: 50% of Time Zone Calculator's written reviews are positive against 80% of TimeShift's, so the app with the better star average is not the one people write more warmly about.
